Detailed Documentation

This document presents valuable programs designed to calculate GPS accuracy factors such as Geometric Dilution of Precision (GDOP) and Position Dilution of Precision (PDOP). The implementations include matrix-based algorithms that process satellite constellation geometry to determine positioning accuracy metrics. Notably, the collection contains a high-precision point positioning program developed in Japan, which features advanced error modeling and kinematic positioning capabilities. These executable programs incorporate key functions for coordinate transformation, variance-covariance matrix computations, and satellite elevation masking. We recommend running these implementations to experience their robust performance in enhancing positioning accuracy and workflow efficiency.
