The clearest signal so far is a Chinese reaction wheel imported through a Russian company which received approximately $1.42 million from Bureau 1440 in 2025\. Other links run through China-origin equipment, Western technology routed through Chinese suppliers and frequent travel by Bureau 1440 personnel to Chinese commercial-space and satellite-manufacturing centers. The links strongly suggest China is helping to keep several difficult parts of Rassvet’s production chain open while sanctions restrict Russia’s access to Western space electronics and engineering equipment. Why does this matter for Ukraine? Because Moscow can begin drone tests well before it finishes a global satellite network. [Russia’s Rassvet Satellites Will Threaten Ukraine with Better Drone StrikesRussia is doubling down on building an independent satellite network, Rassvet, for more lethal drone strikes against Ukraine. Despite several delays, scoped testing has already begun, leaving Kyiv with less time to spin a solution than it might have bargained for.![](https://storage.ghost.io/c/e6/62/e662d7a6-04ff-4444-9a82-4a7463552003/content/images/icon/Screenshot-2025-10-18-at-3.27.49---PM-1-7e768f4d-c6ba-4e4b-a8e6-5ed05809b976.png)DroneSenseDrone Sense![](https://storage.ghost.io/c/e6/62/e662d7a6-04ff-4444-9a82-4a7463552003/content/images/thumbnail/Screenshot-2026-09-25-at-10.03.28---AM-1-e82e2e60-622c-465a-9ccc-34831443643f.png)](https://www.dronesense.ai/can-russias-rassvet-satellites-threaten-ukraine-with-better-drone-strikes/) ****Read How Russia's Rassvet Satellites Can Improve Its Drone Strikes** A limited number of working spacecraft and airborne terminals could support occasional target or route updates for long-range Gerans, while continuous coverage would later make live video and operator control more dependable on medium-range strike drones. > *China’s role could be decisive if its components, production tools and terminal electronics prevent delays to Russia’s first Rassvet-connected drone missions.* ### **Rassvet Can Affect Drone Missions Before It Is Complete** [Russia has launched 32 production Rassvet satellites](https://uisc.eu/blog/from%5Fplans%5Fto%5Forbit%5Fthe%5Ffirst%5Ftest%5Fof%5Frussias%5Frassvet/?ref=dronesense.ai) across 2 batches, but their deployment remains uneven. Only part of the first batch had gathered around the observed 510 km formation by early September, while most of the second batch was still raising orbit. > That remains far below the 156 spacecraft planned for the end of 2026\. However, the tactical threshold for selected drone missions is lower than the threshold for uninterrupted broadband coverage. A long-range drone could continue along a programmed route when no satellite is available, then reconnect during a communications window to transmit telemetry or imagery and receive revised instructions. Russia could consequently begin with localized trials over areas where satellite passes, gateways and military activity overlap. For drones hunting vehicles or other moving targets, the requirement becomes harder. Sustained video, timely steering commands and handovers between satellites would place greater demands on network continuity and the airborne terminal. *But each additional working spacecraft increases the number and duration of connection opportunities available for testing.* This makes the supply chain operationally relevant well before Russia reaches its formal constellation target. Components that help complete another satellite batch or shrink a terminal for airborne use could also bring forward the first missions. ### **Chinese Reaction Wheels are in Rassvet’s Production Chain** ## How Chinese Supply Reaches Rassvet Select a route to isolate the evidence and its effect on Russia's path to satellite-connected drone missions. All evidence Chinese hardware Routed via China Routed via Türkiye Relationship signals Origin→Route into Russia→Rassvet dependency→Effect on drone deployment **Shanghai Modern Aerotech**SMA-D-6 reaction wheel → **Materik**Russian importer paid approximately $1.42 million by Bureau 1440 → **Recurring flight hardware**Satellite attitude and pointing control → **More usable spacecraft**More connection windows for selected drone missions **Western manufacturers**Rohde & Schwarz, Keysight and TOPTICA equipment → **Chinese suppliers**Commercial rerouting channel → **Factory and test capacity**RF, antenna and optical integration → **Faster qualification**Satellite batches and terminals reach deployment sooner **Western manufacturers**Controlled engineering and test equipment → **Turkish suppliers**Parallel commercial route → **Production resilience**Alternative access to factory tools → **Less disruption from sanctions**Russian output becomes harder to delay through one route **Chinese space centers**Commercial satellite and manufacturing clusters → **Approximately 90 employees**Bureau 1440 personnel during 2025 → **Supplier and technical access**Qualification, inspection and integration are plausible functions → **Shorter learning cycle**Fewer delays between imported inputs and working systems **All evidence:** Chinese support affects Rassvet through recurring flight hardware, reusable factory equipment and a broader technical relationship. These routes shorten different parts of the path to drone integration. Chinese-origin hardware Western equipment via China Western equipment via Türkiye Relationship signal DroneSense.ai [Bureau 1440 paid Materik approximately $1.42 million in 2025](https://newsukraine.rbc.ua/analytics/russia-develops-its-own-starlink-who-s-behind-1787306421.html?ref=dronesense.ai), with almost the entire amount denominated in yuan. Materik imported SMA-D-6 reaction wheels made by Shanghai Modern Aerotech, a company that [specializes in satellite attitude and orbit-control equipment](https://modern-aerotech.com/productinfo/19507.html?ref=dronesense.ai). > Chinese SMA-D-6 reaction wheels likely entered Rassvet’s satellite-production chain through Materik. Reaction wheels rotate a spacecraft without consuming propellant, allowing it to control its orientation. For Rassvet, this helps keep solar panels exposed to sunlight and directs antennas or laser terminals toward the correct satellite or ground point. So, the imported hardware supports more than basic flight. Rassvet’s planned laser links and electronically steered communications architecture both depend on controlled pointing. A shortage in attitude-control hardware could consequently hold up an otherwise completed satellite. The Chinese SMA-D-6 also closely resembles the German [Vectronic Aerospace VRW-D-6](https://www.vectronic-aerospace.com/reaction-wheels/?ref=dronesense.ai) in its product designation and published specifications. This suggests a second possible role for China: manufacturing an alternative based on an established Western component family after Russia lost direct access to the original European supplier. > *The reaction-wheel channel shows how one Chinese component can decide whether Russia completes another satellite, even when final assembly remains domestic.* The undisclosed shipment quantity prevents estimating how many spacecraft this channel could support. But the transaction connects a Bureau 1440-funded Russian intermediary to a named Chinese producer of specialized satellite hardware during the shift to Rassvet batch production. ### **The Larger Chinese Role Sits Inside the Factory** The [wider production network includes more than 1,300 entities](https://newsukraine.rbc.ua/analytics/russia-develops-its-own-starlink-who-s-behind-1787306421.html?ref=dronesense.ai), with 150 receiving over RUB 10 million from Bureau 1440 and 21 receiving more than RUB 100 million during 2025\. These numbers show the scale of procurement. Not every supplier is equally important, though. > Supplier criticality still depends on whether a company provides hardware or equipment capable of delaying a satellite. What needs to be differentiated is hardware consumed by every spacecraft and equipment that allows the factory to build and test them. Reaction wheels, processors, memory, sensors, RF components and power electronics are recurring inputs. If every satellite needs them (*as it appears in this case*), Russian output remains tied to the rate at which they can be imported, substituted and qualified. Spectrum analyzers, optical test systems and other engineering equipment work differently, because a single acquisition can still support the development and acceptance of many satellites, gateways and user terminals. [Bureau 1440 made nearly $68 million in foreign-currency payments for imported goods during 2025](https://newsukraine.rbc.ua/analytics/russia-develops-its-own-starlink-who-s-behind-1787306421.html?ref=dronesense.ai). Customs findings traced Rohde & Schwarz, Keysight and TOPTICA equipment through Chinese and Turkish suppliers. These companies produce tools relevant to RF links, antennas, optical systems and communications testing. That creates a layered dependence. China can supply its own spacecraft components, while also keeping Russia connected to Western equipment that remains difficult to reproduce domestically. The largest identified Bureau 1440 payment recipient illustrates the scale involved. Pallada received approximately RUB 1.6 billion during 2025, while most goods in its wider imports originated in China. The product mix supplied to Rassvet remains unclear, but the combination of a large Bureau 1440 payment and heavy China-origin procurement makes Pallada a likely route for equipment used in the program. ### **Production Scale Depends on the Type of Chinese Support** ## What the China Evidence Establishes The evidence separates recurring spacecraft hardware from reusable factory support and wider relationship signals. | Evidence | Route | Rassvet input | Effect on Russian capability | Assessment | | ---------------------------------------------------------------------------------- | ---------------------------- | --------------------------------------------------------- | ----------------------------------------------------------------------------- | ---------------------------- | | Materik imported SMA-D-6 reaction wheels and received Bureau 1440 payments | China → Russia | Recurring satellite flight hardware | Supports spacecraft pointing and usable communications links | Component-level link | | Most goods in Pallada's wider imports originated in China | China → Russia | Product mix supplied to Rassvet remains unidentified | Large payment and China-heavy procurement identify a route worth prioritizing | Indicative intermediary link | | Rohde & Schwarz, Keysight and TOPTICA equipment acquired through Chinese suppliers | West → China → Russia | RF, antenna and optical test equipment | Reusable tools support integration and qualification across several batches | Identified rerouting channel | | Controlled Western engineering equipment acquired through Turkish suppliers | West → Türkiye → Russia | Factory and test equipment | Creates a parallel route when Chinese or direct channels are disrupted | Identified alternative route | | Approximately 90 Bureau 1440 staff travelled to Chinese space centers during 2025 | Russia ↔ China | Supplier access, inspection, training or integration work | Could shorten qualification and troubleshooting cycles | Strong relationship signal | | Russian space-sector agreements to buy Chinese spacecraft electronics | China → Russian space sector | Onboard electronic components | Shows an established national route for replacing sanctioned inputs | Sector-level context | DroneSense.ai #### **(A) Russia Supplies the Structure** Bureau 1440 has localized parts of the chain. Its subsidiary Labs 1440 [launched automated solar-panel production](https://1440.space/en/?ref=dronesense.ai), while Russian entities provide software, spacecraft integration, plasma propulsion, launch services and ground infrastructure. Domestic final assembly can still depend on imported machinery and components. A satellite assembled in Russia can use a Chinese reaction wheel, Western test equipment acquired through China and Russian software running on imported electronics. That model could support limited deployment if the required parts arrive consistently enough for spacecraft to pass testing and leave the factory. #### **(B) Chinese Hardware Keeps Satellite Batches Moving** Russia’s broader space sector has already acknowledged this gap. In January 2023, then-Roscosmos head Yuri Borisov said [Russia had reached agreements to purchase Chinese electronic components for spacecraft](https://interfax.com/newsroom/top-stories/87214/?ref=dronesense.ai) after Western sanctions restricted access to microelectronics. Russian officials later estimated that full replacement of foreign onboard satellite equipment could take as long as 5 years, or even longer. Finished reaction wheels, processors, sensors and power electronics can help Russia complete satellites already moving through assembly. Their impact repeats across every production batch because each new spacecraft consumes another set. #### **(C) Factory Equipment Compounds Across Future Batches** Production machinery, spares and technical support affect the rate at which those components become functioning satellites. Their value compounds because one installed system can support assembly, testing or qualification across several batches. China consequently has 3 routes for reducing Russia’s delay: - Supplying finished spacecraft components that Russia cannot produce at the required rate. - Providing production machinery, spares and technical support that increase factory output. - Acting as a commercial route to Western equipment and component families. The effect of each route is different. Finished components support the next batch, while production machinery and test capacity can affect every batch that follows. > *For Russia’s deployment schedule, the decisive Chinese contribution is likely the one that raises monthly output rather than the one with the largest payment value.* A dependency-weighted view of the 1,300-company network would likely concentrate influence among a small number of suppliers providing recurring flight hardware or factory equipment. ### **The Airborne Terminal Might be the Key Bottleneck** Placing Rassvet on a drone also requires a terminal that the aircraft can carry and power. Bureau 1440’s publicly displayed terminal measures up to 60 × 60 cm and weighs no more than 15 kg. It uses an electronically steered antenna intended to acquire and maintain contact with moving satellites. That size is better suited to a large aircraft, ship or command vehicle. Integration on a disposable long-range drone would place tighter limits on mass, electrical demand, cooling, antenna visibility and cost. China’s electronics industry could help Russia reduce this gap through phased-array components, RF front ends, amplifiers, processors, power-management systems and terminal-production machinery. Russia can also obscure this dependence by installing imported chips or modules on a Russian-designed circuit board and selling the completed terminal as domestically developed. The terminal supply chain is less visible than the satellite supply chain and could set the pace for the first drone missions. Russia can reserve a small number of expensive airborne terminals for selected platforms well before producing them at national scale. Economics would shape that choice. A reusable reconnaissance aircraft can return with its terminal, while an expendable Geran consumes the communications equipment during every successful strike. Russia is likely to initially prioritize higher-value long-range drones, reconnaissance platforms or medium-range aircraft operating against mobile targets, where in-flight control provides enough operational value to justify losing the terminal. ### **China Has Reasons to Support Rassvet, and Reasons to Limit It** Russian demand gives Chinese component manufacturers a market for reaction wheels, sensors, electronics and production equipment. Beijing also gains when Moscow becomes less dependent on American communications infrastructure which can be withdrawn during a conflict. At the same time, China is building its own satellite internet capacity. The [Qianfan constellation reached 256 spacecraft in September 2026](https://wap.miit.gov.cn/xwfb/gxdt/sjdt/art/2026/art%5Fb100b46264bc4c45bd2ba95dcb260771.html?ref=dronesense.ai), giving Chinese companies direct experience in batch manufacturing, flat-panel satellite integration and repeated launches. Rassvet could eventually compete with Chinese constellations for customers, spectrum and political influence across Central Asia, Africa and other markets where both countries seek communications partnerships. *That makes selective industrial support more likely than unrestricted transfer of a complete Chinese satellite design.* [Bureau 1440 personnel travelled to China almost every month during 2025](https://newsukraine.rbc.ua/analytics/russia-develops-its-own-starlink-who-s-behind-1787306421.html?ref=dronesense.ai), with approximately 90 employees involved in visits to major commercial-space and satellite-manufacturing centers. Such frequency suggests a relationship extending beyond an isolated component purchase, and could include supplier qualification, equipment inspection, technical training or integration work. So, a commercial-industrial relationship is more plausible than a formal state-to-state Rassvet program. However, the boundary between both is difficult to draw in the Chinese space sector, where state investment, municipal support, research institutes and commercial manufacturers often operate within the same industrial clusters. ### **Chinese Access can Compress Development Without Eliminating Risk** Chinese equipment can help Bureau 1440 avoid waiting for a complete Russian replacement for every sanctioned component. > Access to existing reaction wheels, electronics and production tools also reduces the number of subsystems Russia must develop from the beginning. But replacement creates its own work. New components must fit the satellite’s electrical, mechanical and software architecture, survive vibration and thermal testing, and perform reliably in orbit. Changing suppliers during the transition from prototypes to serial production can create delays even when the replacement hardware is available. Russia could accept some of that risk to increase output. Commercial or industrial electronics can be supported through shielding, redundancy, error correction, watchdog resets and fault-tolerant software. Shorter spacecraft lives could also become acceptable if the factory and launch system can replace failed satellites quickly. Rassvet’s early orbital behavior makes reliability worth monitoring. One production satellite re-entered, several spacecraft raised their orbits slowly and parts of the second batch remained far below the first formation in early September. The causes remain unresolved across testing, phasing, propulsion, power or individual spacecraft performance. Usable capacity comes after Russia qualifies the design, launches it, raises the spacecraft into the required formation and keeps it functioning long enough to deliver service. ### **Rassvet Would Shift the Jamming Problem** If China helps Russia maintain satellite and terminal production, the tactical result would be a new route for communicating with drones beyond terrestrial radio range. For long-range Gerans, intermittent Rassvet access could allow operators to receive status information and change a target or route after launch. The drone could continue autonomously between connections, using its separate navigation systems to remain on course. For medium-range drones operating against vehicles, continuous service could support live video and steering commands beyond the range of ground relays. Russia could also reduce dependence on mesh networks which need suitable geometry and surviving airborne nodes to move data across the formation. A sovereign service would remove Ukraine’s ability to ask SpaceX to disconnect unauthorized Russian terminals through its access controls. It could also force Ukrainian electronic warfare to identify and suppress another communications architecture while Russian drones continue switching between autonomous flight, terrestrial links, mesh relays and satellite connections. Navigation would remain a separate vulnerability because Rassvet carries communications rather than positioning data. Ukraine could continue attacking the GNSS receiver, while separately trying to interfere with the satellite uplink or downlink. Narrow beams and electronically steered antennas can make that harder than suppressing a common line-of-sight control signal, particularly before the waveform, frequencies and terminal behavior are understood. Airborne terminals could also create characteristic emissions which can be detected, classified and eventually targeted. Other pressure points would remain across gateways, ground infrastructure, software, satellite handovers and recurring component supplies. Physical interception will continue to matter because disrupting the control link may still leave an autonomous drone flying toward preloaded coordinates. > *Rassvet could reduce Ukraine’s leverage over the control link and spread the defensive burden across communications, navigation, electronic warfare and kinetic interception.* ### **China Could Shorten the Gap Ukraine Has to Close** > The central risk is that Chinese access removes enough production obstacles for Russia to begin airborne trials. Chinese reaction wheels likely support the spacecraft chain directly. China-origin imports and Western equipment routed through Chinese suppliers can support integration and testing. The larger electronics ecosystem could also help Russia develop terminals compact enough for selected uncrewed aircraft. This could allow Moscow to introduce satellite connectivity selectively before it achieves uninterrupted coverage or mass terminal production. Ukraine would then need to identify the emissions, understand the protocol, test interference and distribute protection while still addressing radar gaps, mesh-connected drones and autonomous navigation. Supply-chain pressure could delay the Russian side of that timeline, particularly if recurring flight hardware or terminal components are concentrated in a small number of channels. Yet sanctions against a manufacturer will have limited effect when substitutes, intermediaries and stockpiles remain available. Ukraine’s response will consequently have to work across both ends of the system: delaying the industrial chain which produces Rassvet hardware while preparing electronic and kinetic defenses against the drones that receive it. > *China’s role matters because it could shorten the interval between Russia’s incomplete constellation and its first satellite-connected drone strikes. The damage caused during that interval will depend on whether Ukraine prepares before the terminal appears on an aircraft.* ### **What To Watch For** - **Repeat orders for flight hardware:** Another shipment of Chinese reaction wheels or a new Chinese component supplier would indicate recurring dependence across Rassvet production batches. - **Production-line imports:** Chinese equipment appearing inside Bureau 1440’s assembly or qualification process will likely suggest that the relationship is helping Russia increase monthly satellite output. - **An airborne Rassvet terminal:** A verified installation on a Russian drone or sustained flight test would provide the clearest signal that this supply chain is reaching combat integration. #### Sources: [****\[1\] Ukrainian International Strategy Center. “From Plans to Orbit: The First Test of Russia’s Rassvet.”**](https://uisc.eu/blog/from%5Fplans%5Fto%5Forbit%5Fthe%5Ffirst%5Ftest%5Fof%5Frussias%5Frassvet/?ref=dronesense.ai) [****\[2\] RBC-Ukraine. “Russia develops its own Starlink: Who’s behind Rassvet and where it could fail.”**](https://newsukraine.rbc.ua/analytics/russia-develops-its-own-starlink-who-s-behind-1787306421.html?ref=dronesense.ai) [****\[3\] Shanghai Modern Aerotech. “SMA-D-6.”**](https://modern-aerotech.com/productinfo/19507.html?ref=dronesense.ai) [****\[4\] Vectronic Aerospace. “Reaction Wheels: VRW-D-6.”**](https://www.vectronic-aerospace.com/reaction-wheels/?ref=dronesense.ai) [****\[5\] Bureau 1440\. “Rassvet Low-Earth-Orbit Satellite Communications System.”**](https://1440.space/en/?ref=dronesense.ai) [****\[6\] Interfax. “Roscosmos head: China supplying electronic components to Russian space sector.”**](https://interfax.com/newsroom/top-stories/87214/?ref=dronesense.ai) [****\[7\] Interfax. “Roscosmos needs five years for full import substitution of satellite equipment.”**](https://www.interfax.ru/russia/886464?ref=dronesense.ai) [****\[8\] Ministry of Industry and Information Technology of China. “Qianfan networking launch increases constellation to 256 satellites.”**](https://wap.miit.gov.cn/xwfb/gxdt/sjdt/art/2026/art%5Fb100b46264bc4c45bd2ba95dcb260771.html?ref=dronesense.ai) [****\[9\] Ukrainska Pravda. “Russia lost access to Starlink and is building a replacement.”**](https://www.pravda.com.ua/eng/articles/2026/08/08/8047858/?ref=dronesense.ai) [****\[10\] Interfax. “Russia to begin serial satellite assembly in 2027.”**](https://interfax.com/newsroom/top-stories/104800/?ref=dronesense.ai)
