5.6 Gbps optical intersatellite communication link
A 5.6 Gbps optical communication link has been verified in-orbit. The intersatellite link uses homodyne BPSK (binary phase shift keying) and allows to transmit data with a duplex data rate of 5.6Expand
Homodyne BPSK-based optical inter-satellite communication links
A 5.625 Gbps LEO-LEO laser communication link, established between the German satellite TerraSAR-X and the US satellite NFIRE, shall demonstrate the performance and advantages of laser communication.Summer 2007, Tesat will verify laser communication terminals based on homodyne BPSK in-orbit. Expand
High stability, fast tunable single frequency laser source for space based lidar applications
This paper describes the design and performance of the TESAT Reference Laser Head, acting as the frequency reference for the ALADIN Transmit Assembly (TXA) for the ESA AEOLUS satellite. FirstExpand
142 km, 5.625 Gbps free-space optical link based on homodyne BPSK modulation
A free-space optical link based on homodyne BPSK (binary phase shift keying) has been established between two of the Canary islands, La Palma and Tenerife, to transmit 5.625 Gpbs across 142 km. ThisExpand
In-orbit verification of optical inter-satellite communication links based on homodyne BPSK
Laser communication terminals based on homodyne BPSK are under in-orbit verification in LEO-to-ground and duplex LEO-LEO 5.65 Gbps links. With the LEO-to-ground link beacon-less acquisition has beenExpand

We present an overview of the inter-satellite optical terminal technical evolution since the beginning of ESA and German Space Agency Studies in the seventies up to the current LEO constellation optical inter-Satellite link terminals as developed by Bosch. Expand
Optical inter-satellite links based on homodyne BPSK modulation: heritage, status, and outlook
For a number of reasons homodyne BPSK (binary phase shift keying) is superior to all other optical modulation schemes. Since BPSK has been verified as a reliable technique for space applications,Expand
Space qualified ultra stable laser source
We present for the first time an optical transmitter based on a miniature monolithic monolithic Nd:YAG laser, which covers the whole range of space applications. Expand
Highly-coherent optical terminal design status and outlook
After 30 years of development coherent satellite laser terminals will verified in orbit in 2006. General design constraints for space communication optical terminals are reviewed and the design andExpand
