An Architecture Design of Navigation Solution Using Signal Information from Global Navigation Satellite System

Abstract:

This research endeavor probes into the implementation of navigation solution using the signals of Global Navigation Satellite System (GNSS) from the Garmin GPS-25 OEM board after getting the raw data in the NMEA format. The position information obtained by the receiver is compared with the navigation algorithm implemented in MATLAB. The Ionospheric, Tropospheric and relativistic clock errors are incorporated to achieve the required accuracy. The Least square iterative algorithm is applied to get the position information. The geometric, position and time dilution of precisions; GDOP, PDOP and TDOP respectively are also compared and analyzed. The GNSS structure, the signal in space, the sources of positioning errors, the pre-processing techniques and data formats are also presented to complete the problem. The analytical treatment validates the problem solution too.
