Paper Abstract
Starting in late 2007 and continuing through the present, NFIRE (Near-Field Infrared Experiment), a
Missile Defense Agency (MDA) experimental satellite and TerraSAR-X, a German commercial SAR
satellite have been conducting mutual crosslink experiments utilizing a secondary laser communication
payload built by Tesat-Spacecom. The narrow laser beam-widths and high relative inter-spacecraft
velocities for the two low-earth-orbiting satellites imply strict pointing control and dynamics aboard both
vehicles. The satellites have achieved rapid communication acquisition times and maintained
communication for hundreds of seconds before losing line of sight to the counter satellite due to earth
blockage. Through post-mission analysis and other related telemetry we will show results for pointing
accuracy, disturbance environments and pre-engagement prediction requirements that support successful
and reliable operations.
