| Abstract: | This paper analyzes the GDOP’s geometric operations process of Loran C single-chain hyperbola line of position.Using MATLAB,it simulates GDOP distribution in the South China Sea from region 15 ° N,108 ° E to region 23 ° N,116 ° E.Simulation results show that "Chang He-II" system in the South China Sea positioning error is small,but in the region from(15 ° N,108° E) to(23 ° N,110 ° E) near the sea GDOP value larger.This explains the reason that chains geometry distribution in the region near the coastline could lead to positioning failure. |
