| Abstract: | This paper is based on the measured data of the Loran C typical cover range and combined with the principles of Loran C positioning, timing, and operation situation. Through the theoretical analysis and statistical calculation, timing and positioning differences between the GPS and Loran C receivers and between different types of Loran C receivers at the same point under the same conditions are quantified; the main factors restricting Loran C timing accuracy are analysed and summed up;some opinions and suggestions to solve the problem are put forward to provide the reference and support for effectively improving the positioning and timing accuracy of Loran C system. |
