Starting in late 2007 and continuing through the present, NFIRE (near-field infrared experiment), a Missile Defense Agency (MDA) experimental satellite and TerraSAR-X (TSX), a commercial SAR satellite partially funded by the German Space Agency (DLR), have been conducting mutual crosslink experiments utilizing a secondary laser communication payload built by Tesat-Spacecom and also funded by the DLR. In addition, both satellites have conducted link tests to the ground using a ground terminal built by Tesat as well as 1-μm receivers at various observatories. The satellites have routinely spatially acquired each other in 4 seconds and maintained communication for hundreds of seconds before being blocked by the earth. More stressing inter-satellite links are currently under test in addition to space-to-ground links from more ideal locations (better atmosphere and weather). (5 pages)
