The ship’s onboard Ku communications antenna SCX3R100
-
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;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;3. Industrial-grade
components are adopted to ensure the reliability of components;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;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.
