The German Flying Laptop satellite, launched on 14 July 2017 on a Soyuz launch vehicle from Baikonur Cosmodrome in Kazakhstan, [1] hosts the OSIRISv1 laser communications experiment. [2] The satellite has a total mass of 110 kg. [3] It operates at a 600 kilometres (370 mi) Sun-synchronous orbit with an inclination of 97.6 degrees. [4]
The satellite is part of the Stuttgart Small Satellite Program, a program led by the German Space Agency.
Optical communications tests have been carried out with ground stations in Japan, Europe, and Canada, [5] with a data rate of up to 200 Mbit/s, from orbit to ground only.
The two fixed lasers of OSIRISv1 are aimed at ground stations by 'body pointing', attitude control of the entire satellite, using four reaction wheels. [3] The reaction wheels can be desaturated using three internal magnetorquers. [3]
Flying Laptop carries a de-orbit mechanism called DOM2500 developed by Tohoku University and manufactured by Nakashimada Engineering Works, Ltd., which upon activation will unfurl a sail to increase atmospheric drag. [6] [7] The device will be used at the end of the satellite mission. [8]
