Embodiment 1

[0051] Such as figure 1 As shown, it is a flow chart of the satellite tracking method of the mobile antenna carrier in this embodiment; the satellite tracking method includes:

[0052] S1. Acquiring motion posture data and current geographic location information of the mobile antenna carrier;

[0053] Wherein, the mobile antenna carrier is a mobile carrier including a ship with an antenna, and the antenna is a double reflector antenna, including a main reflector and a secondary reflector. The motion attitude data includes the angular velocity and inclination angle values ​​of the mobile antenna carrier on the three direction axes, and the current geographic location information includes the current longitude and latitude of the mobile antenna carrier. The angular velocity and inclination angle values ​​of the mobile antenna carrier on the three direction axes also represent the angular velocity and inclination angle values ​​of the antenna on the three direction axes. The thr...

Embodiment 2

[0074] This embodiment provides a satellite tracking device for a mobile antenna carrier, the antenna includes a main reflector 201 and a secondary reflector 202, combined with Figure 6 As shown, the device includes:

[0075] Inertial navigation system 60, which is used to acquire the motion attitude data of the mobile antenna carrier; GPS module 70, which is used to acquire the current geographic location information of the mobile antenna carrier;

[0076] A controller 10, which is used to calculate the elevation angle, azimuth angle and polarization angle of the antenna 20 according to the motion attitude data and the current geographic location information, and angle output-drive signal;

[0077] Adjust the motor unit 30, which is used to control the rotation of the antenna 20 according to the driving signal, so that the antenna 20 locks the direction of the satellite;

[0078] Brushless motor 40, which is used to control the rotation of the sub-reflector 202; frequency ...

Embodiment 3

[0095] Like the satellite tracking device described above, the difference of this embodiment is that the controller 10 takes the phase reference signal as a reference, superimposes the satellite signal strength value and performs multi-point calculation to obtain the antenna 20 The main reflector 201 deviates from the angle of the satellite, and outputs an adjustment signal according to the angle, including:

Abstract

The invention provides a satellite tracking method and device for a mobile antenna carrier. The antenna comprises a primary reflecting surface and a secondary reflecting surface. The method comprisesthe following steps: obtaining moving posture data and current geographical location information of the mobile antenna carrier; calculating an angle of pitch, an azimuthal angle and a polarizing angleof the antenna according to the moving posture data and the current geographical location information; controlling the antenna to rotate according to the angle of pitch, the azimuthal angle and the polarizing angle so that the antenna locks the direction of the satellite; controlling the secondary reflecting surface to rotate, obtaining a satellite signal strength value and collecting a phase reference signal generated when the secondary reflecting surface rotates for one circle; with the phase standard signal as the standard, superposing the satellite signal strength value for multi-point calculation and obtaining an angle of the primary reflecting surface deviating from the satellite; controlling the primary reflecting surface to perform angle adjustment according to the angle until thesatellite signal strength value remains unchanged. The satellite tracking method greatly improves the reliability and stability of the antenna locking the satellite.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a satellite tracking method and device for a mobile antenna carrier. Background technique [0002] With the expansion of maritime business, ships have become an important living place for sea workers. In order to provide TV and communication signals for sea workers, ship-borne satellite antennas are indispensable. Facing the harsh external environment on the sea and the violent shaking of the ship caused by the impact of waves, it is difficult for the ship-borne satellite antenna to lock the satellite stably and accurately in real time, and it is difficult to ensure that the satellite signal will not disappear. Contents of the invention [0003] In view of this, the present invention aims to propose a satellite tracking method for a mobile antenna carrier to solve the problem that it is difficult for a ship-borne satellite antenna to lock satellites stably and a...
