The invention provides a method, a system, a medium and equipment for autonomously initializing an orbit determination filter during orbit adjustment of a satellite. The method comprises the following steps: step 1, performing adjacent acceleration difference out-of-range event identification in unit time; step 2, carrying out burr identification and disposal on an out-of-range event; and step 3, identifying and disposing a thruster ignition or flameout event. According to the method, the function of autonomously initializing the filter at the thruster ignition moment and the thruster flameout moment is achieved, and it is guaranteed that a navigation receiver can rapidly output high-precision positioning data and orbit determination data during satellite orbit adjustment.
本发明提供了一种卫星调轨时定轨滤波器自主初始化方法、系统、介质及设备,包括:步骤1:进行单位时间内的相邻加速度差超范围事件识别;步骤2:进行超范围事件的毛刺识别与处置;步骤3:进行推力器点火或推力器熄火事件识别与处置。本发明实现了推力器点火时刻和推力器熄火时刻自主对滤波器初始化的功能,保证了卫星调轨时导航接收机可以快速输出高精度的定位数据和定轨数据。
