Abstract

This study explores a new navigation method using multi-path solar panel-reflected solar oscillations. Considering the solar panels of BeiDou-3 M1–M24 and GPS satellites as examples, the simulations show that the mean position error of FY-1 using solar panel-reflected solar oscillations is only 20.61 m in 30 days. Compared with the existing autonomous navigation methods for the Earth satellites, the newly proposed method has two advantages. (1) It has the highest navigation accuracy. (2) It does not require any additional accurate geomagnetic map, gravity gradient map, or refraction model. While the proposed method requires at least two atomic frequency discriminators to obtain the measurements and its accuracy is affected by the geometric relationship between the Earth satellite, reflected satellite, and Sun, which are the inherent drawbacks of the method. It is notable that the influence of the relativistic effects on the measurement accuracy needs further research.

利用太阳电池板反射的太阳振荡为地球卫星提供多路径导航方法
本研究探索了一种利用多路径太阳电池板反射太阳振荡的新型导航方法。以北斗三号 M1-M24 卫星和 GPS 卫星的太阳电池板为例,模拟结果表明,利用太阳电池板反射太阳振荡的 FY-1 号卫星在 30 天内的平均位置误差仅为 20.61 米。与现有的地球卫星自主导航方法相比,新提出的方法有两个优点。(1) 导航精度最高。(2) 它不需要任何额外的精确地磁图、重力梯度图或折射模型。而提出的方法需要至少两个原子频率鉴别器才能获得测量结果,且其精度会受到地球卫星、反射卫星和太阳之间几何关系的影响,这些都是该方法的固有缺点。值得注意的是,相对论效应对测量精度的影响还需要进一步研究。
