A GPS Reseiver for Space Applications

Kurzfassung

This report presents the development of a cost effective GPS reiceiver for space applications conducted at DLR`s German Space Operations Center (GSOC). Building up on the existing GPS Orion receiver design by Mitel Semiconductor multiple units for sounding rockets and satellite usage have been built up. Developments specific to the space application comprise software modifications to ensure signal acquisition and precise navigation under hight dynamics as wess as hardware modifications for integrating the receiver into exsting bus systems. Aside from hardware-in-the-loop simulations for a lab-based receiver validation, first flight results obtained during sounding rocket missions are described. In addition, current missions in which the receiver will be utilized are presented and future development lines are described.
