Abstract

There has been a burgeoning of activity involving the establishment and operation of permanent GPS stations. The variety of applications is broad, from geodetic reference sites in support of IGS initiatives, to national base stations for real-time differential GPS, “integrity monitoring” and datum maintenance, and even local GPS base stations providing data to surveyors and other users. The level of sophistication of such permanent stations also varies, from systems capable of automatic data collection, transmission and sometimes processing, to relatively simple configurations. All applications, however, share a concern for GPS data “quality”. The detection of cycle slips, data “spikes”, multipath disturbances, and bad data sequences of GPS measurements is a major problem for many applications, even more so in the case of real-time applications.

Some quality control (QC) strategies may be implemented either on a single receiver basis or using GPS network data. This paper discusses the issue of QC for permanent GPS receivers, and comments on aspects of QC which require investigation.
