A method to compute location in GNSS denied area

This paper discusses a method to compute the location of the receiver in the area where the signal from the Global Navigation Satellite System (GNSS) such as GPS and GLONASS does not reach or weak. These areas are called GNSS denied environment. The method in takes the initial location obtained from GNSS system as seed to further compute the location of the receiver using interpolated and extrapolated positions using dead reckoning module (DRM). This paper further discusses the design of such a locating device which uses both data obtained from GNSS and DRM to compute the position information where GNSS signals are not available or weak.
