Necmettin Erbakan University Continuously Operating Reference Station

Abstract

The Continuously Operating Reference Stations (CORS) are geodetic grade Global Navigation Satellite System (GNSS) receivers with permanently installed antennas, that are collecting GNSS data 24/7. Today the CORS, has vital importance in the GNSS community, whether for civilian users or researchers. Global CORS networks were established such as International GNSS Service’s network. Also, most of the countries are established their own CORS networks e.g. Turkish CORS-TR. With the CORS networks, access to GNSS data for different purposes has become easier. In addition, for educational or some other research purposes it can be necessary to establish a CORS station. For this purpose, a CORS station was established at the rooftop of Necmettin Erbakan University. NEU-CORS station can track GPS, GLONASS, Galileo, BDS and SBAS satellites. The collected data is archived in the standard formats, and a real-time data stream via the Internet is provided. In this study, NEU-CORS station was introduced. The specification of the reference receiver, antenna and data formats are explained in detail. However, sample data is presented to examine the SNR (Signal to Noise Ratio), multipath and satellite visibility.
