摘要:
针对于目前地磁传感器测量精度较低,将其信息直接用于飞行器再入段定高误差较大的问题,提出了一种在线预测进行定高的方法。该方法在已知定高点的地磁强度条件下,利用再入段过程中的测量数据进行建模并实时预测到指定高度的时间。以目前常用的商用地磁传感器HMC2003的特征参数进行Monte-Carlo试验仿真。
Abstract:
Against the big error of height determination for the reentry vehicle because of the information provided by low precision geomagnetic sensor,a novel real-time prediction method is proposed.This method uses the output of a geomagnetic sensor during the reentry of the aircraft to build a model and makes a real-time prediction of the time when the aircraft reaches the expected height.Monte-Carlo simulation is conducted using the characteristic parameters of a commercial geomagnetic sensor HMC2003.
