摘要
以罗兰C覆盖范围内典型区域实测得到的数据为基础,结合罗兰C定位、定时工作原理,通过理论分析和统计计算,量化了相同条件下同一点GPS与罗兰C接收设备、不同种类罗兰C接收设备之间的定时定位差异,剖析归纳出制约罗兰C定时精度提高的主要因素,并提出了解决问题的意见、建议,为有效提升我国罗兰C系统的定时定位精度提供参考与支撑。
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.
