The Results of Software Joint Processing of Signals from Global and Regional Navigation Satellite Systems

Resumo

The paper considers joint software processing of signals from global (GLONASS, GPS, BeiDou, Galileo) and regional (IRNSS) navigation satellite systems. A general block diagram of the prototype multiconstellation software-defined radio (SDR) is presented; its capabilities to process signals from navigation systems are discussed. The developed SDR allows for separate and combined navigation solutions using signals received in Russia’s North-West from 30 satellites of 5 different navigation systems. The accuracy of these solutions and the DOP values are analyzed.
