Kepler Network (optical data relay)
A constellation of laser-linked relay satellites that carries data for other spacecraft, letting them downlink quickly instead of waiting for a pass over a ground station.
Why it matters
Most satellites can only send data when they are over a ground station, which can delay images and sensor readings by hours. A relay network in orbit means faster delivery for weather, defense and disaster response users.
How the technology works
Kepler's satellites link to each other and to customer spacecraft with optical (laser) terminals designed to work with Space Development Agency systems, and carry onboard computing. Data hops across the network and comes down through more than 10 optical ground stations.
Kepler plans a next tranche from 2028 with terminals rated up to 100 Gbps.
