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.
