摘要
航天测控中,需要避免过于复杂的运算过程,提高计算速度时,常常运用一些近似公式。分析了近似公式的作用、来源,以及在航天测控中的一些应用情况。提出了一种航天测量船实战使用的简化的大气折射修正公式,并对事后使用的精确公式进行了对比分析,结果表明,运用简化的大气折射修正公式处理后的数据在定轨精度上满足要求,同时满足了实时数据处理对计算速度的要求。
The approximate formula is often adopted to enhance the computation speed and avoid the complicated calculation. We briefly discussed the source and applications of the related approximate formulae in space-tracking engineering. At last,a new method of a simplified formula about atmospheric refraction correction used on TTC ship was proposed,and then we compared it with an accurate formula used on accurate handling. The result shows that the accuracy of initial orbit based on simplified formula is satisfied and the speed of compute is satisfied.
