GNSS Remote Sensing with Small Satellites

A constellation of small satellites (here MicroGEM) can exploit GNSS signals with innovative techniques to significantly improve the remote sensing of the System Earth.
Lupe

A major motivation for the small satellite activities at GFZ was the extremely successful GPS radio occultation experiment aboard the CHAMP satellite [1]. Later, the application of GNSS-R within future generation Tsunami Early warning systems was investigate in more details as part of the GITEWS project [2]. Based on these investigations in total three feasibility studies for the definition of small satellite projects with scientific GNSS payload were performed: MicroGEM [3], NanoGEM [4], and NanoX [5]. Additional objective of these missions is geodetic co-location usingthree different space geodetic techniques (GNSS. VLBI and SLR).

GFZ is recently involved in small satellite project for GNSS-Reflectometry of the RUAG company in cooperation with the European Space Agency ESA (PRETTY, [6]).
