Measurement of Tracking Accuracy of Antenna Using Precise Geostationary Satellite Orbit
The conventional method to measure the tracking accuracy of antenna is based on the boresight tower. But the accuracy of this method is not very high because the result is easy to be disturbed by reflecting electromagnetic wave from ground, surrounding buildings and terrains under low elevation in measuring. And a boresight tower and a lot of corresponding equipments are needed in this method. It costs both time and money. This paper presents a new method of using precise geostationary satellite orbit to measure the tracking accuracy. It is easy to operate. Moreover, the accuracy of this method is higher than the conventional one. The feasibility of the new method is validated in comparison with the conventional one, so it can be used in the construction and maintenance of ground stations.
