Characterization and Performance Assessment of BeiDou-2 and BeiDou-3 Satellite Group Delays [PDF]

open access: yesNAVIGATION: Journal of the Institute of Navigation, 2022
Based on one year of data, a comprehensive assessment of broadcast group delays and differential code biases (DCBs) from network solutions is presented for all open BeiDou signals. Daily DCB estimates exhibit a precision of 0.1 ns, which also places a limit on long-term variations of the satellite group delays.

Validation of BeiDou Observations [PDF]

open access: yesJournal of Applied Geodesy, 2014
AbstractThis study presents validation of BeiDou measurements in un-differenced standalone mode and experimental results of its application for real data. A reparameterized form of the unknowns in a geometry-free observation model was used. Observations from each satellite are independently screened using a local modeling approach.
