An I2C interface is used for sensor communications. Ethernet with UDP on a custom developed three layered frame organisation of sensor data serves as a link to the main system on board of an aeroplane. For backing up the acquired data, all frames are locally stored on an SD Card. To have the possibility of easily checking the current system status, an LCD module and a push-button provide a minimal user interface.}, language = {en} } @inproceedings{ZentgrafBergeChassetetal.2010, author = {Zentgraf, Peter and Berge, S. and Chasset, C. and Filippi, H. and Gottzein, E. and Guti{\´e}rrez-Ca{\~n}as, I. and Hartrampf, M. and Krauss, P.

The expected benefits of using the GPS receiver for Small GEO are explained. The feasibility of using GPS for position determination is investigated by simulation using a MosaicGNSS receiver, which was stimulated by a Spirent RF signal generator. A procedure, how to evaluate flight data on ground is outlined. Success criteria of the experiment and the minimal size of the downlink stream required and reserved for the receiver TM are presented.}, language = {en} }
