Product overview

The SATPRO GA300 brings satellite communications to small and medium general aviation aircraft, including crewed and uncrewed platforms. It enables real-time video return, IP voice calls, broadband internet access and data return during flight. Applications include forest fire prevention, power-line inspection, border reconnaissance and geographic surveying. Its waveguide horn array antenna uses automatically adjusted linear polarization, with continuous 360° azimuth rotation, 0°–90° elevation travel and at least 180° of polarization travel. Inertial navigation measurement and beacon/carrier tracking support antenna tracking.

The system incorporates the MODMAN airborne satellite communications control terminal, integrating a modem, antenna control unit and video codec for signal processing, system control, and video and voice output. One-touch satellite acquisition automatically tracks and locks onto the satellite and completes network entry after startup. OPENAMIP supports automatic switching between beams. Operating-state recording and display, power-loss memory and protection, startup self-test and fault alarms support system operation. Video encoding supports H.265, H.264SVC and H.264 dual-channel compression, with 1080P, 720P and D1 resolutions.
