Shipborne broadband satellite communication antennas are communication devices tailored for ships to connect land and sea, and sea and sea. The antenna adopts a three-axis stabilization structure and has built-in high-precision tilt sensors, magnetoresistive sensors, and gyroscope sensors, which can monitor changes in external angles in real time and make real-time attitude adjustments to ensure that the antenna automatically searches for and tracks satellites, maintaining uninterrupted communication even in harsh sea conditions.
