Abstract
Due to high cost and difficult to achieve real-time monitoring of receivers with the existing RTD technology, this paper proposes the inverse real-time pseudo-range differential technology (IRTD) based on CORS, which adds data center server between receiver and CORS system, transferring differential calculating from receiver to data center server. Data center server receives raw pseudo-range sent back by the receiver and RTCM data broadcast by CORS system, gets positioning result through parallel algorithms and returns location information to the receiver for displaying. Experiments show that without increasing data traffic, IRTD can solve the work area control problem, maintain secrecy of local coordinate parameters, realize real-time monitoring of multi-terminal, which can hardly be solved by the traditional RTD technology. And with a better accuracy, IRTD has a wide application prospect in rapidly obtaining and updating urban spatial information.
