Abstract :
The ionospheric error is an important error source for GPS user. In order to eliminate this error, using a good method for correcting ionospheric error is necessary. In this paper, the author analyzed the virtue and flaw of these correction methods, used a method of dual-frequency pseudo range and carrier phase measurement to eliminate the ionospheric error of observation path, estimated the accuracy of dual-frequency correction methods and applicable scope, and verified the dual-frequency ionospheric error correction methods is feasible and effective.
