Flying Laptop is a small satellite and amateur radio satellite that was developed at the Institute for Space Systems at the University of Stuttgart from 2004 and launched on July 14, 2017.

mission

Flying Laptop has four mission objectives: training, technology testing, earth observation and building infrastructure.

Flying Laptop was developed and manufactured by doctoral students at the University of Stuttgart. Students were involved in the project through courses, internships and theses. Essential elements of the satellite bus are new developments within the framework of industrial cooperations that are to be tested in space as part of the Flying Laptop Mission. Large parts of the payload were developed at the Institute for Space Systems and are also to be tested. Flying Laptop has two camera systems in different spectral ranges for earth observation and vegetation analysis. In addition to a control center and a ground station with an S-band antenna system, a clean room was built at the Institute for Space Systems in which the satellite was integrated.

system

Flying Laptop is a three-axis stabilized satellite with a mass of approx. 120 kg and a volume of 60 × 70 × 85 cm. Three solar panels, two of which can be unfolded, are installed to generate energy. Communication takes place in the commercial S-band , payload data is transmitted in the non-commercial amateur radio range of the 13-centimeter band . In addition to optical payloads, a receiver for the Automatic Identification System (AIS) and a laser downlink experiment are installed.

In the first phase of the flight, three ground stations of the German Aerospace Center are in contact with the satellite: Weilheim in Bavaria , Inuvik in Canada and GARS-O'Higgins in Antarctica . Later on, the IRS ground station in Stuttgart was mainly in contact with the satellite. In addition, a ground station at the Geo Research Center Potsdam in Ny-Ålesund on Spitsbergen is used to receive additional satellite data.

Mission history

The launch took place on July 14, 2017 from Baikonur in Kazakhstan . The first telemetry data was received in Germany that same evening. After successful commissioning in orbit, the first image recorded by the satellite was received on the ground five days after the launch. The data collected by the Flying Laptop are now being recorded and evaluated in routine operation. All satellite systems are working stably and a large number of mission objectives could be achieved in the first year of operation.
