[0045] 1. An inertial / GNSS / satellite beacon combined moving antenna stable tracking method, the implementation process is as follows figure 1 As shown, specifically including the following steps:
[0046] ①The angular rate information of the base measured by the inertial system Obtain the angular rate information in the antenna coordinate system through coordinate conversion among them:
[0047] ω ‾ a = C b a X ω ‾ b - - - ( 1 )
[0048]
[0049] θ a , Γ a , They are the pitch angle, roll angle, and azimuth angle of the base coordinate system relative to the antenna coordinate system;
[0050] ② will As the command angle, the first-level stable tracking control is performed on the antenna, where ω ‾ a = ω a x ω a y ω a z T , ω a x , ω a y , ω a z They are the angular velocity of the pitch axis, polarization axis, and azimuth axis of the antenna c...
