Research on Multi Satellite Failure Detection and Recognition Method of Satellite Navigation RAIMt observation values of receiver itself. This article first makes a comparative analysis to the conventional and recently proposed RAIM fault detection and identification methods, and then points out that the conventional fault identification methods have such weakness as low fault detection probabi

Ionospheric Threat Model Methodology for China Area enough measurement in a limited areas monitored by the network. The spatial threat model is constructed to restrict the ionospheric behavior under these under-sample scenarios for a more stringent bound. In this work two ionospheric spatial threat model, namely ‘blob’ and ‘wall’ models are construc

Real-Time Cycle Slip Detection and Repair Algorithm for SBAS Airborne Receivery SBAS augments GPS L1 signal, such as WAAS and EGNOS, providing APV-I service. Receiver uses GIVD to correct ionosphere delay, in which way the impact of ionosphere storm cannot be eliminated. Thus, SBAS performance is limited. Dual frequency SBAS receiver directly mitigates ionosphere delay. Howev

Study on Space-Based All Source Navigation Technologyvigation used satellite navigation signal to obtain the position and time reference to generate the navigation signal, and then broadcast through the microwave downlink. It is a new scheme and the cost is relative low. In the paper, the payload carrying platform, signal receiving, building and maint
