Paper Abstract

This paper describes an earth orbiting Deep Space Relay Satellite System (DSRSS) based on optical coherent detection communication for the user spacecraft to DSRS link. The optical coherent detection DSRSS is considered as a possible augmentation to the Deep Space Network (DSN), after the 70 meter antennas are upgraded to Ka Band near the turn of the century. While significant development is required and technical complexity issues remain, the coherent optical system appears capable of achieving the desired order of magnitude improvement relative to the Ka Band DSN. For example, the coherent optical system provides a capability of 670 kbps at Pluto (40 A.U.), a 10.4 dB improvement over the upgraded DSN.
