Validation of BeiDou Observations [PDF]
Journal 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.

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

OSA Patient Monitoring Based on the Beidou System [PDF]
Frontiers in Public Health, 2021 This paper presents an OSA patient interactive monitoring system based on the Beidou system. This system allows OSA patients to get timely rescue when they become sleepy outside. Because the Beidou position marker has an interactive function, it can reduce the anxiety of the patient while waiting for the rescue.
