1. The built-in high-precision inertial navigation module in the shipboard satellite communication antenna measures the attitude of the ship in real time. The attitude stability algorithm with independent intellectual property rights is operated by DSP, which ensures that the antenna aims at the target satellite in real time under any circumstance;3. Industrial-grade components are adopted to ensure the reliability of components;5. In terms of production process, after long-term high-temperature and low-temperature aging test, the cable is close to the quality of military products.
4. In terms of software algorithm, it has built-in space coordinate transformation module, PID stability module and other core modules, whose control frequency is greater than 200Hz;
2. The mechanical structure of the three axis stabilized platform, to ensure the high level of star control precision (pointing to the accuracy of + / – 0.2 °) and mechanical reliability;
