Key Takeaways
- NEC Corporation is developing a satellite to test technologies for future optical communication satellite constellations aimed at improving data transmission.
- The satellite, set to launch in fiscal year 2027, will demonstrate advancements in radiation-hardened optical transceivers, high-speed network routing, and mmWave communications.
- Collaboration with Apex Technology aims to accelerate satellite development and production efficiency in the burgeoning field of space communications.
Overview of the Project
NEC Corporation has announced plans to develop a small technology demonstration satellite that will verify essential technologies for future optical communication satellite constellations. This satellite will focus on areas such as optical communication, high-speed network routing, and high-capacity mmWave band communications. The design phase for the satellite’s payload is complete, and production is set to begin, with an expected launch during fiscal year 2027.
Optical communication is becoming increasingly favored for satellite-to-satellite interactions, distinguishing itself from conventional radio methods. This modern approach aims to minimize communication interference and enhance data transmission capabilities. With the rise of satellite constellations consisting of many small satellites, the need for shorter development times and reduced costs has become imperative. Therefore, using proven, general-purpose technologies is vital.
For satellite constellations to function effectively, particularly as high-speed, dynamically moving mesh networks, substantial computational power is necessary for routing processes that enable low-latency communications. This has led to the need for applications specifically designed for space environments, which differ substantially from terrestrial network designs.
To address these challenges, NEC’s planned technology demonstration satellite will execute several critical in-orbit demonstrations, offering insights that ground-based tests cannot provide.
Key Demonstrations
The technology demonstration satellite will showcase three main technologies:
-
Radiation-Hardened Optical Transceivers: NEC will evaluate the performance of commercial optical transceivers designed to withstand space radiation, aimed at ensuring high-capacity transmission capabilities on small satellites.
-
High-Speed Network Routing Technology: The demonstration will utilize a Versal(TM) Adaptive SoC device from AMD for testing high-speed data routing via optical satellite constellations. Additionally, the application development methodology will incorporate NEC’s satellite technology with generative AI to enhance future satellite projects.
-
Next-Generation mmWave Communications: To prepare for future high-capacity transmissions, NEC will demonstrate mmWave Q/V-band transceiver equipment, which will also establish communications with ground stations to gather data on radio wave propagation.
The satellite framework will employ the compact Aries satellite bus, an existing product from U.S.-based Apex Technology, intended to streamline development and mitigate risks associated with satellite manufacturing.
The partnership between NEC and Apex Technology emphasizes NEC’s aspirations to lead in optical communication technologies within space infrastructure. Ian Cinnamon, CEO of Apex Technology, highlighted that this collaboration aims to accelerate satellite deployment while enhancing the industry’s capabilities for mass production.
Yasushi Yokoyama, General Manager of NEC’s Satellite Constellation Department, stated that the company is committed to creating social value through the effective use of space technologies. This initiative aligns with broader projects supported by the Economic Security Critical Technology Development Program and the Space Strategy Fund Project, aimed at advancing technologies for optical communication satellite constellations.
As the project moves forward, NEC is dedicated to pursuing technological developments to establish a new digital infrastructure in space, reinforcing its position in this essential area of innovation.
