GPS and EAR/GEANS Software Support.
Abstract
The Air Force Avionics Laboratory is sponsoring development of both the Generalized Development Model (GDM) of GPS User equipment, and the EAR/GEANS radar/inertial navigator. This report documents results of analysis and software support for both of these programs. GPS-related analysis has been performed in the area of GDM software support, particularly, stability analysis of alternate designs for rate-aiding of non-coherent mode of GPS receiver; vertical channel analysis and simulation; improved GPS/Inertial Simulator model implementation; and integrated GPS/strapdown performance studies. EAR/GEANS-related analysis has been performed in the areas of Error Isolation Filter (EIF) development planning; vertical channel error modeling; error modeling for GEANS space-stable baro-inertial navigator; EAR radar measurement modeling; EAR/GEANS flight test data recording; gravity perturbation modeling; EAR/GEANS Error Isolation Filter synthesis; onboard feedback correction compensation in the EIF; and EIF optimal filter/smoother mechanization equations selection.
