Abstract Aiming at overcoming the difficulties of using TCAR method to fix ambiguity of Beidou triple-frequency long-baselines, we propose a sliding window method to fix the ambiguity of EWL, WL and NL. In long baselines, according to the experimental analysis of the relationship between window size and ambiguity successful rate, the ambiguity successful rate is mainly affected by ionospheric and tropospheric delays. Therefore, we use the sliding window method to fix EWL and WL ambiguities, the GIF-TCAR method to calculate NL ambiguity, at the same time using the sliding window method to fix NL ambiguity. The results indicate that this method can be used in BDS triple-frequency processing for real-time navigation and positioning.
