Description
At the KEK Tsukuba Campus, seven GS10 GNSS receivers have been installed at the delivery building and the auxiliary utility building, which are located along the SuperKEKB ring road, to collect positioning observation data continuously since 2012.
Previously, specialised analysis software was used to calculate receiver positions from this data; however, due to license expiration, a large volume of observation data had accumulated without being processed into positional information. To address this, the open-source GNSS analysis software RTKLIB was employed to compute positions from the unprocessed data and convert it into an analysable format.
This report presents an evaluation of the accuracy and validity of positional data obtained through data conversion and positioning analysis using RTKLIB, based on observations collected by the seven GNSS receivers installed at the facility.
