Detection and Correction of Antenna Phase Center Error of GPS
Zhu Hua · 2012
The GPS antenna phase center error is an important error sourse that affecting the precision of GPS.Consequently,in high-precision GPS location measurement,the antenna should be oriented and the model should be used to correct the antenna phase center.The relative detection method of specification was provided,which was used to detect the horizontal component and vertical component of antenna phase center offsets.The shortcomings of this method were analyzed.According to these shortcomings,a new method was put forward.The case proved the method had a high accuracy and reliability and it could be used to detect the horizontal component in the wild.
