Research on Measurement Technology of Length and Area Based on COMPASS Positioning

摘要

This paper studies the Compass Positioning and WI-FI positioning etc. for single point positioning and measurement of distance between two points in the error range. As a reference, GPS measurement data with accurate positioning is shown else. On this basis, calculation rules of the area measurement by which the Compass system of irregular region mining point positions into regular polygon approximation is explored, and then the rule method is used to calculate the cumulative area measurement for complex and irregular terrain. It can be shown with irregular area. The experimental data and the measurement results show that the relative error of Bei-dou Positioning length, within distance between 100-200m, is less than 5%, and area measurement error of the regular shape is within 3%.
