Embodiment Construction
[0019] The present invention is described in further detail below in conjunction with accompanying drawing:
[0020] refer to figure 1 , the adaptive integrated navigation antenna beam control method of the mobile communication satellite communication system of the present invention comprises the following steps:
[0021] 1) Establish the system equation of the satellite communication system in motion, the state quantity x of the integrated navigation attitude estimation system is selected as the position error δr of the carrier, the velocity error δv of the carrier and the attitude angle error ψ of the carrier, that is, x=[ δr, δv, ψ] T , then the system equation of the integrated navigation attitude estimation system is: x · = F x + G u , In the formula: F = F ...
