“…General information on the LCT Inter Satellite Link (ISL) technology and its ISL acquisition procedure can be found in [7]. When using this technology for downlinks, the diffraction limited acquisition scan process of the space terminal is hindered by the atmospheric fading and beam wander.…”

The increasing resolution of earth observation sensors will require much higher data rates for the data downlink in future than is feasible with conventional RF-technology. This applies for earth observation satellites as well as for aeronautic observation platforms, such as aircraft or stratospheric high altitude platforms. The most promising solution for this data downlink bottleneck is the application of optical free space transmission technologies. DLR has built diverse atmospheric flight terminals and performed several trials of optical downlinks from space (together with partnering organizations) as well as from atmospheric carriers in recent years. Here we present and compare results of such communication system trials.

“…1 shows the integration of the LCT on the NFIRE satellite. After commissioning phase, the first successful ISL in terms of bidirectional communication was established on February 21 st 2008 [4,5]. Today the LCTs are operated on a routine basis with 97 successfully performed bidirectional communication links and numerous additional experimental links.…”

“…Satellite optical coherent technologies have been validated by the German in-orbit validation laser communication terminals, which were designed for low earth orbit (LEO) to optical ground station (OGS) links (5.625 Gbps) [6], as well as LEO-LEO links [4,5]. Both the German LEO-geosynchronous earth orbit (GEO) link (1.8 Gbps) [7] and the American laser communications relay demonstration (LCRD) (2.88 Gbps) [8] are based on coherent receiving technologies.…”
