A Probe into Channel Delay Measurement Program of GPS Monitoring Receiver Based on Online Delay Self-correcting
2021
One of the important factors affecting the monitoring receiver ranging accuracy of GPS monitoring receiver is the channel delay error, and the effect of the variation in especially high latitude environment temperature on channel delay must be taken into consideration. A statistical analysis is carried out on the data of receiver channel delay which varies with environment temperature by using the online delay self-correcting method in the Paper. From the results, it is clear that the receiver channel delay varies with temperature regularly, and the receiver’s ranging accuracy can be effectively improved by modifying the channel delay of the receiver according to the environment temperature.
