Static Test with GPS, Glonass and EGNOS Receivers

Risultato della ricerca: Articlepeer review


In this work the author show the results of testing conducted in last few years within the network of University of Palermo called UNIPA NRTK GNSS. The University of Palermo, in order to carry out scientific tests on the use of CORS networks for real time positioning, have realized a network of reference stations. The network was set up during a National Research Scientific Project entitled: "Networks of permanent GPS stations for survey in real time control and use of emergency" and was the first made in Sicily for scientific GNSS-NRTK research but is also used for topographic and cartographic applications. The goal of the work is to verify the reliability of the network infrastructure (successful tests, failed initialization time, satellite configurations) and the repeatability assessment of the accuracy of measurements positioning. Reliability and repeatability was evaluated considering the possibility of receiving the correction in VRS, FKP or EGNOS mode in surveys conducted in different areas and in different days. Accuracy was determined by comparing the coordinates of some points calculated in post-processing and NRTK or EGNOS surveys. Some test-areas with different characteristics are chosen to valuate reliability and accuracy. In selected test-areas we have been considered 35 vertex, including some of IGM95 network and other to local network. The static measurements were performed on different days than those of the surveys NRTK and was carry out with 40 hours of occupation time, with different geometric configuration.
