Although it's not the normal way, GPS positioning can also be helped using Doppler measurements: http://gpsworld.com/gnss-systemalgorithms-methodsinnovation-doppler-aided-positioning-11601/ My intro contains a little bit of Doppler history. -- Richard Langley P.S. My instrument onboard the Canadian CASSIOPE research satellite contains 5 GPS receivers. We can get very good orbital positions (a few metres in real time and much better than that using post-processed data). ----------------------------------------------------------------------------- | Richard B.
