Feasibility of Code-Level Altimetry Using Coastal BeiDou Reflection (BeiDou-R) Setups [PDF]

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2015
With the development of the Chinese BeiDou satellite navigation system, the applications of BeiDou-reflected (BeiDou-R) signals will play a key role in Global Navigation Satellite System-reflected (GNSS-R) signals. In this paper, we describe the theory of code-level ocean surface altimetry using BeiDou-R signals.

Yaw Attitude Modeling for BeiDou I06 and BeiDou-3 Satellites

GPS Solutions, 2018
The estimated yaw angles of the BeiDou I06 satellite demonstrated that the satellite experienced midnight- or noon-turn maneuvers when the sun elevation angle above the orbital plane (β angle) was in the range of [− 3°, + 3°] and the orbital angle was in the range of approximately [− 6°, 6°] or [174°, 186°].

Accuracy and reliability of BeiDou clocks

Journal of Applied Geodesy, 2023
Abstract The subject of this paper is the analysis of the stability of BeiDou system clocks; currently only signals from two blocks, BSD-2 and BDS-3, are available. For elaboration, 30 s clock corrections from the 2014 to 2020 period for 37 satellites were used (9 IGSO, 28 MEO).

Simulation Analysis of Positioning Performance of BeiDou-2 and Integrated BeiDou-2/GPS

2010 International Conference on Communications and Mobile Computing, 2010
A new method has been proposed for assessing availability of satellite navigation system. Software has been compiled to simulate BeiDou-2 (BD-2) constellation with 12 satellites and GPS constellation. Based on 27 stations of Crustal Moment Observation Network of China, satellite visibility, dilution of precision (DOP), and availability of BD-2, GPS and
