Many satellites in LEO use a GNSS-based navigation system, taking advantage of the GNSS constellations in MEO to enhance navigation capabilities. The thesis work focused on developing the software enabling GNSS-based navigation for Hemeria's future small satellites operating in LEO. Real time algorithms were developed to perform on board accurate frame conversions based on the International Earth Rotation and Reference Systems Service 2010 convention. The implementation was tested and independently cross-validated using space mechanics libraries and data from Observatory of Weights and Measures of Paris. The method was based on the Earth Orientation Parameters, and the balance between autonomy and accuracy was assessed. In pursuit of an aff...
