Abstract
In Taiwan, there are more than one hundred GPS tracking stations maintained by Ministry of the Interior (MOI), Academia Sinica, Central Weather Bureau and Central Geological Survey. In the future, they may take place of the GPS controlling points after given a legal status. Therefore, the data quality of the tracking stations has become more and more important. This paper addresses the feasibility of establishing a system for monitoring GPS receivers.
In this study, many data quality indexes were adapted and the relationships of the indexes and the positioning precision were found. The frequency stability of GPS receiver is the most important index, the cycle slip is the second index, and the multipath is the third index. According to the results, the auto-analytical system of GPS data quality was established and the MOI’s tracking stations were monitored. When the receiver get some problems or there is a change of the station’s environment, we hope to find and resolve the problems earlier to ensure the high data quality of the tracking stations.
