Flying Laptop

From Wikipedia, the free encyclopedia

The GermanFlying Laptopsatellite, launched on 14 July 2017 on aSoyuz-2.1alaunch vehicle fromBaikonur CosmodromeinKazakhstan,[1]hosts theOSIRISv1laser communications experiment.[2]The satellite has a total mass of 110 kg.[3]It operates at a 600 kilometres (370 mi)Sun-synchronous orbitwith an inclination of 97.6 degrees.[4]

The satellite is part of the Stuttgart Small Satellite Program, a program led by theGerman 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 controlof the entire satellite, using fourreaction wheels.[3]The reaction wheels can be desaturated using three internalmagnetorquers.[3]

Flying Laptop carries a de-orbit mechanism called DOM2500 developed byTohoku Universityand 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]
