| 摘 要： | 为满足测量船高精度测控模式下对电波折射修正精度的需求,针对测量船采用的高斯分层积分法具有较高精度、但存在计算复杂且不具有实时性的缺陷,提出了一种电波折射误差修正的新方法,将距离折射表示成天顶距离误差和仰角因子的函数关系,解决了测量船实时电波折射误差修正精度差的问题,满足了测量船数据处理的精度需求。

| Abstract: | The Gaussian quadrature method based on atmospheric sphere sublayer model used by TT＆C ship is accurate, but it is too complex to be used in real - time calculation. To satisfy radio wave refractive correction accuracy requirements under the mode of high -precision TT＆C, a new radio wave refractive correction method is proposed, which can calculate the range refractive error by multiplying zenith path delay and elevation formula. This method solves the problem that radio wave refractive correction accuracy is unsatisfied with real - time calculation, which can be used for space tracking ship＇ s data processing as needed. |
