The antenna has a built-in high-precision inertial navigation module to measure the attitude of the ship. The attitude stability algorithm with independent intellectual property rights is operated by DSP, which ensures that the antenna can be aimed at the target satellite in real time in any situation.
When searching for a satellite, the elevation Angle of the target satellite is calculated according to the geographical position obtained by GPS, and the target is searched directly on the basis of triaxial stability, so the target can be acquired quickly.
In the aspect of target recognition, in order to improve the reliability of satellite signal recognition, a signal plus beacon recognition method is specially designed.
Mechanical aspects, using the mechanical structure of the triaxial stability, ensure the control accuracy, stable platform of pointing accuracy of + / - 0.2 °).
In terms of electronic components, industrial-grade components are adopted to ensure the reliability of components (military-grade components can also be provided).
In terms of software, it adopts high-speed DSP calculation, built-in coordinate transformation module, PID stability module and other core modules, and its control frequency is greater than 500Hz.
The reliability of electrical components is guaranteed by long time high and low temperature aging test.
