    • Abstract
  • Doppler and phase-rates are used to evaluate velocities.The different characters of the two methods are put forward.A new method of detection of cycle slips-double differentiated phase-rate bias is shown.The results indicate that the accuracy of velocity deduced from raw Doppler observations is 20~70 mm/s and that from derived Doppler can be 1~3 mm/s.
