OSIRISv1 is the first generation of terminals in the OSIRIS family.
With OSIRISv1, the Institute of Communications and Navigation has developed a compact laser terminal with a maximum data rate of 200 Mbit/s. With a total weight of only 1.3 kg, it can be deployed on almost all small satellites. A coarse alignment unit was not incorporated into the terminal. The laser beam control is therefore based purely on the position control of the satellite, or in other words, the satellite controls the laser beam with its position control to the optical ground station.
OSIRISv1 was launched in July 2017 along with the small satellite Flying Laptop of the University of Stuttgart into an orbit at the height of approximately 600 km and has been available for experiments since then.
