The Navigation Precision Analysis of the Measurement Ship of Shelter Condition

Abstract:

Based on the Analysis of pseudo-range positioning principle and the precision evaluating method, the navigation antenna shelter models of GPS and COMPASS in measurement ship are established. And then the varieties of the geometry dilutions of precision are analyzed in condition of the different shelters. Results show that the geometry dilutions of precision increases due to the large-scaling shelter, the requirement of overlay can’t be satisfied in some region. The overlay ratio of the navigation system will be increased via improving the height of the navigation Antenna location. The overlay of the COMPASS is forecasted and analyzed in shelter condition in order to provide evidences for the measurement ship navigation and follow-up application of COMPASS.
