Adapting 100G Optical Comm to Unique NASA Small Satellite DSM Applications

We proposed to expand the bandwidth of free space optical (FSO) communications tonbsp;100G for lunar and Lagrange points while using available low-cost and low size, weight, and power (SWaP) technologies. We propose to develop 100G space laser transceiver technology that specifically address the unique properties of these longer-range missions and bridging the gap between terrestrial and Geo, Lunar and L1/L2 mission applications. This is in contract to LEO efforts where the range is 1000km.This program will develop Cubes, Small and Large Satellite, mission ready, TRL 6 technology ready for program infusion in an ultra-compact 1 kg, lt; 1 U CubeSat form factor with the expected reliability for long duration missions. The program leveraging cost effective terrestrial fibercom 100G,nbsp;photonic integrated circuits, coherent modules for long-range space-based free space optical (FSO) links.Our link budget indicates that 100G-200G is feasible with a ground station telescope of 1-6nbsp;meters in diameter, with smaller 10-20 cm satellite telescopes.The proposed technology is supports GEO downlink, GEO-GEO, Lunar, and potentially L1 andnbsp;L2 ranges with sufficient ground station receiver aperture.Supports NASA Scan office roadmap for 100G everywhere in space.Support very long-range utilizing NASArsquo;s Optical and RF combo Telescope and antenna system currently under development. The telescope diameter is 5-10 meter telescope being developed by NASA for DSN applications.High bandwidth is a key enabler to expand NASA human spaceflight operations, telerobotic, astronaut HD video and SMD science for Lunar missions.Enables NASA Heliophysics vision for affordable, sun sensing SmallSat constellations at L1, L2 for space weather, astronaut safety missions and SMD heliophysics science.Technical approach leverages terrestrial fibercom photonic integrated circuit (PIC) providing advanced technology at low cost for space.Ready for program insertion in 2025.
