The Phoenix GPS Receiver - A Practical Example of the Successful Application of a COTS-Based Navigation Sensor in Different Space Missions

Dies ist die aktuellste Version dieses Eintrags.

Kurzfassung

Most Earth-orbiting satellite missions planned and realized over the last two decades have at any point considered to employ a GNSS receiver in the satellite bus or even as scientific instrument for atmospheric research or Earth observation. Unfortunately, for the majority of these projects, a fully space-qualified GNSS receiver is out of reach due to the extremely high costs typically associated with hardware specifically designed and qualified for space use. For projects with a more confined budget choosing a COTS-based version of the desired device or instrument is often the only viable alternative. Motivated by this considerations, as well as the need for affordable GPS technology in internal rocket and satellite projects, DLR's space flight technology group has commenced to explore, develop and test COTS-based GPS sensors about 20 years ago in the late 1990s. As an outcome of this work, among others, the Phoenix GPS receiver for space applications has been developed, qualified and successfully flown in numerous space missions. Moreover, the receiver has also been made available to various external small- and mid-scale space projects, including LEO satellites, satellite launchers and sounding rockets. In this talk, the Phoenix GPS receiver will be introduced to the audience. An overview about the conducted space qualification program will be provided. Finally, a summary of the so far obtained flight results and gathered experience will be presented.
