Calculating Station Bias for Uncalibrated GNSS Stations using Close-Range Calibrated GNSS Station Data

Global Navigation Satellite Systems (GNSS) provide continuous navigation data to study the ionosphere's everchanging characteristics and effects on radio communication. Satellite hardware biases are readily available and remain consistent across the globe. However, station bias is specific to the station location and hardware, and it is not readily accessible for uncalibrated stations. In this work, a new technique has been proposed that uses data from a close-range calibrated station to calculate the station bias for a non-calibrated GNSS station. Initial findings show promising and accurate results, where the station bias is within a range of 1ns to 1.22ns compared to the station bias calculated by other previously existing techniques (Ma and Maruyama 2003). Our technique's accuracy allows us to reliably calculate TEC for SHJ1 or any uncalibrated station around the globe.
