摘要
由于星载设备的运算量、存储量的限制,在保证所需精度的前提下,根据卫星轨道的具体特点,尽可能地简化轨道改进、预报和摄动计算公式,对此提出基于GPS的星载简化解析法,采用一阶分析摄动理论和部分田谐项摄动。通过实例,证明该方法可在满足一定精度的情况下降低定轨方案的复杂度,具有一定的工程应用参考价值。
It should simplify the formula of satellite orbit improvement, forecasting and the perturbation calculation with the precondition of assuring required accuracy, due to constrains of onboard operating and storing. A simplified analytical of method based on GPS is proposed. The perturbation model only includes first analytical theory and parts of tesseral harmonics in this method. The real example shows that the method can decrease complexity of orbit determination meeting the need of accuracy, thus values to engineering application.
