Effect of Atmosphere on Satellite Navigation Signal Delay and Correction Method |
|
() |
Abstract: |
The effect of the ionosphere and troposphere on satellite navigation signal delay is presented. The relative positioning and delay model correction algorithm for correcting the atmosphere effect are discussed. The method of dual - frequency observation correcting ionosphere delay error is analyzed in detail. |
Key words: satellite navigation system ionosphere troposphere relative positioning model correction dual - frequency observation |
