Relative Pseudo-distance Deviation DCB

Signal deviation is a systematic error which must be controlled and compensated precisely for satellite navigation ionospheric and precise positioning applications. CAS Center has constructed a series of methods for unified processing and accurate determination of multi-mode GNSS signals applicable to Beidou and compatible with other navigation satellite systems, which avoids the dependence of common methods on a large number of global reference stations or prior ionospheric information, and can achieve results with comparable or even better accuracy by using fewer reference stations. The relative formal deviation DCB and absolute formal deviation OSB products processed by CAS have been routinely submitted to the most authoritative international IGS organization.
