“…3). The displayed tacking stations belong to the international GNSS Monitoring and Assessment System (iGMAS) network (Jiao et al, 2011) and the IGS Multi-GNSS Experiment (MGEX) network (Montenbruck et al, 2014). The three-dimensional coordinates of the IGS tracking stations had been obtained from the IGS published coordinate solution.…”

“…The experiments were performed at the international GNSS Monitoring and Assessment System (iGMAS) [21] sites: SHA1 (Shanghai, China, 31°5.98′ N, 121°12.03′ E) and KUN1 (Kunming, China, 25°1.80′ N, 102°47.47′ E). The sites were equipped with Unicore UB4B0I multi-frequency multi-GNSS receivers and NOV750 choke-ring antennas.…”

Code multipath is an unmanaged error source in precise global navigation satellite system (GNSS) observation processing that limits GNSS positioning accuracy. A new technique for mitigating multipath by installing a wave-absorbing shield is presented in this paper. The wave-absorbing shield was designed according to a GNSS requirement of received signals and collected measurements to achieve good performance. The wave-absorbing shield was installed at the KUN1 and SHA1 sites of the international GNSS Monitoring and Assessment System (iGMAS). Code and carrier phase measurements of three constellations were collected on the dates of the respective installations plus and minus one week. Experiments were performed in which the multipath of the measurements obtained at different elevations was mitigated to different extents after applying the wave-absorbing shield. The results of an analysis and comparison show that the multipath was mitigated by approximately 17%–36% on all available frequencies of BeiDou Navigation Satellite System (BDS), Global Positioning System (GPS), and Global Navigation Satellite System (GLONASS) satellites. The three-dimensional accuracies of BDS, GPS, and GLONASS single-point positioning (SPP) were, respectively, improved by 1.07, 0.63 and 0.49 m for the KUN1 site, and by 0.72, 0.79 and 0.73 m for the SHA1 site. Results indicate that the multipath of the original observations was mitigated by using the wave-absorbing shield.
