Real‐time precise orbit determination for FY‐3C and FY‐3D based on BDS and GPS onboard observation
IET Radar, Sonar &Navigation, Volume 17, Issue 8, Page 1213-1229, August 2023., 2023 (1) The real‐time precise orbit determination (POD) for low earth orbit (LEO) satellites based on spaceborne global positioning system (GPS) and BDS‐2 observations are executed. (2) Code multipath piece‐wise linear (PWL) error model of BDS‐2 satellites is constructed and applied to real‐time LEO POD.

Signal‐in‐Space and Positioning Performance of BDS Open Augmentation Service
Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 As a typical augmentation satellite system for centimeter‐level positioning, PPP (Precise Point Positioning) service based on PPP‐B2b signal of China’s new generation BeiDou system (BDS‐3) was released for Asia‐Pacific area on July, 2020. This paper first introduces the recovery theory of PPP‐B2b SSR (State Space Representation) messages and then ...

Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 As the signals of Galileo and the global BDS‐3 navigation satellite system have been accessible, positioning users can use quad‐frequency even five‐frequency signals nowadays. With multifrequency signals, one can form some useful combinations to improve the positioning performance, e.g., the widely used extra‐wide‐lane (EWL)/wide‐lane (WL) in triple ...

Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 Precise point positioning (PPP) is used in many fields. However, pseudorange multipath delay is an important error that restricts its accuracy. Pseudorange multipath delay can be considered as the combination of effective information and observation noise; it can be modeled after removing the observation noise.
