European Spaceborne Dual Frequency GPS Receiver for Science and Earth Observation

M. Sust, A. Carlström, A. Garcia-Rodriguez

Abstract:	Global navigation satellite system receivers can be used as spaceborne earth observation instruments with the most prominent applications being precise orbit determination and radio occultation. For this type of missions a high precision dual-frequency GPS receiver has been developed and qualified. A high level of integration has been achieved by using application specific integrated circuits for radio-frequency signal processing, analog-to-digital conversion and channel processing. Innovative receiver software, executed on a LEON processor, facilitates application specific tailoring of the receiver hardware. Flexibility is also offered by a compact low multi-path antenna concept, allowing for interconnecting several antenna elements to support beam-forming. The measured receiver performance agrees with theory and is well within the allocated budgets.
