Abstract This paper studies the realization of the Beidou wide-area differential real-time ionospheric delay grid correction algorithm in China, and the short-term establishment of the ionospheric delay grid for the Beidou system. Results of BDS-only, GPS-only, and BDS/GPS combined ionospheric delay grid corrections are analyzed and compared. Results show that BDS-only and GPS-only ionospheric delay grid corrections performance are equivalent in the region, with sufficient effective grid point coverage, and the BDS/GPS combined ionospheric delay grid corrections have higher accuracy and improve the positioning accuracy of single frequency user.
