| Abstract | The article presents a case study of cycle slips detection in dou- ble differenced L1 carrier phase observations collected with two low-cost single frequency GPS receivers operating in both static and kinematic mode. The receivers deliver half-cycle carrier phase observations. Cycle slips are identified using expected Doppler shift. Expected Doppler shift is computed from the positions and the velocities of the satellites and the receivers. A static and a kinematic experiment are carried out. In the static experiment both GPS receivers are stationary while data are collected, whereas one receiver is mounted on a moving car in the kinematic experiment. In the static experiment, cycle slips with a magnitude of 0.5 cycle are easily detected. In this case the positions of the receivers are estimated from col- lected code observations, and the velocities of the receivers are zeros as they are stationary. In the kinematic experiment, the positions of the receivers are again esti- mated from code observations, and the velocities of the receivers are esti- mated from collected Doppler shift observations. The accuracy of the esti- mated velocities is so poor that the expected Doppler shift does not make it possible to detect cycle slips with a magnitude of 0.5 cycle. Cycle slips must have magnitudes of several cycles in order to be safely identified. Computer simulations indicate that the velocities should have a standard deviations of 0.05 m/s or less in order to detect 0.5 cycle slips. |
