JAESat is a joint micro-satellite project between Queensland University of Technology QUT, Australian Space Research Institute ASRI and other national and international partners, i.e. Australian Cooperative Research Centre for Satellite Systems CRCSS, Kayser-Threde GmbH, Aerospace Concepts and Auspace which contribute to this project. The JAESat project is conducted under the leadership of the Queensland University of Technology. The main objectives of the JAESat mission are the design and development of a micro satellite in order to educate and train students and also to generate a platform in space for technology demonstration and conduction of research on a low cost basis. The main research objectives of JAESat are the in-orbit test and validation of the SPARx receiver and its performance, the performance of the on-board Orbit Determination OD concept, the test of an integrated GPS-Star Sensor system concept for a 3-axis Attitude Determination AD and its related algorithms and also various aspects of Relative Navigation. The aspects of atmospheric research will not be addressed within this article. This article will describe the overall JAESat concept and concentrate on the QUT space applications receiver SPARx and related GPS software concepts for OD and AD. The test environment for the development of GNSS space applications will be outlined and finally simulations and respective results including GPS hardware in the loop will be presented and discussed.
