There are many reasons why cycle slips occur. Common reasons include:
- (1) Satellite signal interruption, such as being blocked by high-rise buildings, mountains, trees, bridges, etc., causing satellite signals to be temporarily interrupted.
- (2) The signal-to-noise ratio of the satellite signal is too low, such as the satellite altitude angle is too low, the ionosphere changes drastically, or the multipath effect is too large, etc.
- (3) The receiver is in relative motion. For example, during RTK measurement, it is severely interfered by external factors, causing the satellite signal to temporarily lose lock.
- (4) Receiver or satellite
