Abstract

The next generation GNSS radio occultation instrument under development at RUAG Space will take advantage of the new signals of Galileo, GPS, GLONASS, and Compass. The measurement performance is improved as compared to the present instrument generation that operates on the MetOp satellites. A tracking algorithm has been developed which ensures that all signal information throughout the atmosphere is made available for ground processing with a minimum of losses. Simulation results are presented for a demanding case of a rising occultation.
