[0043] Before using the foldable portable flat-panel satellite communication alignment adjustment device, the user conducts a comprehensive inspection of the satellite terminal to ensure that the satellite terminal is normal and the battery 12 has sufficient power. The user places the satellite terminal flat on the ground or other supports. After the movable legs 18 are placed on the ground or other supports, the user presses down with the weight of the satellite terminal itself, and the limit lock hook 17 slides from the outside to the inside in the sliding limit card slot 15. When the limit lock hook 17 slides to the rear end of the sliding limit card slot 15, the sliding limit card slot 15 limits the limit lock hook 17, limits the angle of the movable legs 18, and automatically locks and fixes the rotating bracket 2, which greatly enhances the stability of the satellite terminal.

According to the longitude and latitude data of the satellite in the processor module database, the processor module calculates and obtains the three angle values ​​of polarization, pitch and azimuth, and the processor module transmits the calculated data. To the sensor module, under the auxiliary work of the auxiliary star module, the driving motor in the polarization transmission mechanism 23 is controlled to rotate, and the polarization shaft drives the pitch bracket 20 to rotate according to the measured polarization angle. At the same time, the planetary reducer stepper motor in the pitch transmission mechanism 24 is controlled to rotate, and the output spline shaft drives the pitch bracket 20 to rotate according to the measured pitch angle. At the same time, the driving motor in the azimuth transmission mechanism 25 is controlled to rotate, and the azimuth shaft drives the fixed seat 13 and the satellite terminal fixed on the fixed seat 13 to rotate as a whole according to the measured azimuth angle. After reaching the measured angle value, the rotation stops, and the antenna surface assembly 3 is aligned with the satellite, and the automatic satellite search is successful;

The flat-panel satellite communication alignment adjustment device is a device for adjusting the satellite. The communication equipment transmits the collected voice, video, data and other information to the modem through a wireless router and a voice gateway. The modem converts the voice, video, data and other information into digital signals. The up-conversion power amplifier performs frequency conversion. After the signal is amplified to sufficient power, the flat-panel satellite antenna sends it through the satellite. The flat-panel satellite antenna receives the digital signal sent by the satellite, amplifies the signal through a low-noise down-converter, and transmits it to the modem. The modem converts the digital signal into an analog signal, which is transmitted to the communication equipment through a voice gateway and a wireless router. When the work of the foldable portable flat-panel satellite communication alignment adjustment device is completed and the satellite terminal finishes work and is stored, the satellite terminal is lifted, the movable leg 18 is quickly retracted, and the positioning ball screw 26 automatically fixes the movable leg 18. Specific embodiment 2:

[0046] When the LCD display screen 5 of the foldable portable flat-panel satellite communication alignment device shows that the battery 12 is low on power, the user takes out the charging controller, inserts the charging head of the charging controller into the power interface 11 of the satellite terminal, and uses AC power to charge the battery 12.
