All right reserved.As the new modernize Global Navigation Satellite System (GNSS), BeiDou Navigation Satellite System (BDS), with its unique constellation, is expected to enhance the positioning performance in Asian-Pacific, especially in Indonesia region. To assess the data quality and positioning performance of BeiDou in respect with GPS (Global Positioning System), an experimental network has established in Bandung, Indonesia using COMNAV T300 GNSS receivers. This research investigates the satellite visibilities, multipath, Signal to Noise Ratio (SNR), and positioning performance. Here are the results of the conducted experiment. It is shown that in every epoch, at least ten satellites are visible. The SNR for B1, B2, and B3 vary from 40 to 50 dB Hz, the multipath variation of GEOs (Geostationary Earth Orbit Satellites) varies within ~1 m, while the multipath variation of IGSOs (Inclined Geosynchronous Orbit Satellites) and MEOs (Medium Earth Orbit Satellites) vary larger than GEOs’. In addition, BeiDou system improves the precision on absolute positioning, as well as the relative positioning. However, there was a west shifting tendencies of BDS estimated position in respect with GPS positioning on the absolute positioning.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]BeiDou,Beidou navigation satellite systems,Data quality,Geostationary earth orbit satellites,Global Navigation Satellite Systems,GNSS,Gps (global positioning system),Position Performance[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]BeiDou,Data quality,GNSS,GPS,Position Performance[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]Authors would like thank to Geotronix Indonesia for providing COMNAV T300 GNSS receivers which are used in this research.
