Abstract:	Addition of new GNSS constellations in space evolved a new concept of multi-GNSS receivers to replace single GNSS receivers. Multi-GNSS receivers can improve accuracy of user’s position with better robustness against ionosphere scintillations, multipath and interference from jammers. However, the performance multi-GNSS receivers badly effected during moving under high dynamic scenarios such as under dense trees or in urban canyons with high rise buildings and narrow roads with multiple flyovers and trees. In these environmental conditions, receivers can hardly navigate precise position due to loss of signal power or complete loss of signals. In this paper, we proposed and investigated a deeply coupled INS/multi-GNSS architecture. We validated the performance of proposed architecture by means of tests under different conditions and real time scenarios. Results are analyzed for the navigation solution availability and tracking performance in accordance by integrated and without integration. Improvements in navigation accuracy justify the superiority of proposed integrated architecture over standalone system.
