Optical Communications



Sinclair Interplanetary is currently working on optical communications for small spacecraft.

 Optical CrosslinksThese are symmetric full-duplex crosslinks that can move 100 Mbps between two satellites 250 km apart. 

Crosslink Datasheet
 Optical DownlinksThe satellite downlink incorporates a star tracker for guidance, which can also be used as a general ADCS sensor for the spacecraft.  It has a data rate of 1 Gbps at 1000 km slant range.

The ground station is a 22" Newtonian telescope, incorporating coarse and fine star guidance cameras.

For safety and regulatory simplicity there is no uplink or beacon laser in the ground segment.
