| Abstract: | The influence of low elevation satellite signals on the resolution accuracy was analysed by use of the Bernese software to calculate tropospheric refraction error and the positioning of the elevation error under different satellite elevation angles.It is concluded that with cutoff elevation angle of 5 degree the good accuracy can be reached. |

| Keywords: | low GPS satellite elevation mask angle troposphere delay estimation elevation positioning accuracy |
