1 March 2006 Mars laser communication demonstration: what it would have been
Author Affiliations +
The Mars Laser Communications Demonstration Project completed a preliminary system design for sending data at 1-30 Mbps from a spacecraft orbiting Mars. The flight transceiver diameter was 30.6 cm, transmitting 5 W average laser power at 1064 nm and using 32- and 64-ary pulse position modulation (PPM). A ground network comprised of two receive terminals (5-m and 1.6-m effective diameter) and two transmit terminals for sending 1076 nm lasers would have been used to communicate with the transceiver.
