Methods of location using GNSS simulators and devices thereof

摘要

A method, GNSS simulator, and non-transitory computer readable medium for providing a simulated global navigation satellite system (GNSS) signal. The method includes receiving, by a GNSS simulator, a precision timing signal and one or more items of ephemeris data from a GNSS receiver based on a decoded GNSS signal received by the GNSS receiver. The precision timing signal and the one or more items of GNSS ephemeris data are received in a digital format over a communication network. A simulated GNSS signal is generated, by the GNSS simulator, based on the received precision timing signal and one or more items of ephemeris data. The simulated GNSS signal is transmitted, by the GNSS simulator, over a coverage area. A GNSS system for providing a simulated GNSS signal is also disclosed.
