DoD space agency funds development of laser terminal that connects to multiple satellite at once:
The Space Development Agency [SDA] awarded BridgeComm and Space Micro a $1.7 million contract to demonstrate point-to-multipoint communications
Each of the satellites in the Pentagon’s planned mesh network of communications satellites could have as many as many as four laser links so they can talk to other satellites, airplanes, ships and ground stations.
Optical inter-satellite links are critical to the success of the Space Development Agency’s low Earth orbit constellation — known as Transport Layer — that will be used to route data traffic. Lasers provide much higher transmission data rates than traditional radio-frequency communications but are also far more expensive.
SDA recently awarded nearly $1.8 billion in contracts for 126 satellites for the Transport Layer. By some estimates, about $500 million of that total would be for optical terminals, said Michael Abad-Santos, senior vice president of business development and strategy at BridgeComm, a Denver-based optical communications startup.
The company developed a so-called “one-to-many” optical communications technology for point-to-multipoint transmissions. This technology could help reduce the cost of building constellations by requiring fewer terminals, Abad-Santos said.
