Satellite communication

Mobile communication (Satellite Communication on the Move) refers to the system that realizes satellite communication on mobile carriers (such as vehicles, ships, aircraft, etc.). Since the mobile carrier is in a state of constant motion, the communication antenna can be aligned with the satellite in real time to ensure the stability of the communication link. Inertial navigation plays a key role in this process. With the rapid development of the low-orbit satellite communication industry, the market demand for satellite communication terminals is gradually increasing.

In the system, accurate carrier attitude information is the basis of antenna alignment with satellite. For example, in the process of vehicle driving, the road bumps, vehicle steering and acceleration movements will lead to the body posture changes. The inertial navigation system can monitor these attitude changes in real time and provide the attitude data to the antenna control system. According to these attitude information, the antenna control system adjusts the antenna azimuth angle, pitch angle and polarization angle parameters, so that the antenna can track the satellite in real time and maintain the stability of the communication link.
