Additional Thoughts and Findings on Satellite Induced GNSS Phase Shifts, Receiver Tracking and the Impact on RINEX and RTCM

The modernization of existing GNSS and upcoming new GNSS changes the conditions for applications using phase measurements significantly. The changes do not only originate from additional satellites, but also from the variety of different frequencies and different signals available from the GNSS systems. In parallel, the receiver development is progressing and simultaneous tracking provides already multiple phase measurements on the same carrier frequency.
