A Closed-form Localization Method Utilizing Pseudorange Measurements from Two Non-synchronized Positioning Systems [PDF]
, 2020 In a time-of-arrival (TOA) or pseudorange based positioning system, user location is obtained by observing multiple anchor nodes (AN) at known positions. Utilizing more than one positioning systems, e.g., combining Global Positioning System (GPS) and BeiDou Navigation Satellite System (BDS), brings better positioning accuracy.

Feasibility of Code-Level Altimetry Using Coastal BeiDou Reflection (BeiDou-R) Setups
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.
