Product Detail

This product is a Ka-band satellite internet phased array terminal developed for mobile platforms. It enables real-time communication with satellites through fast beam scanning and supports high-speed transmission of images, voice and video. Adopting high-density integration of array and TR components, it features two-dimensional electronic scanning and large-angle coverage, with built-in self-calibration algorithm to ensure high beam pointing accuracy.

The terminal integrates transmit/receive antenna arrays, up/down converters, BeiDou navigation and positioning, integrated control and inertial navigation unit. It supports program tracking and automatic tracking with tracking accuracy ≤ 1/4 half-power beamwidth. Operating at uplink 27.5–31GHz and downlink 17.7–21.2GHz, it provides EIRP ≥50dBW and G/T ≥10.5dB/K at boresight, with circular polarization and switchable receive polarization. Powered by DC12V, power consumption ≤1000W, dimensions ≤1250mm×800mm, weight ≤65kg. Equipped with dedicated power, control and multiple RF interfaces, it is ideal for vehicle-borne, ship-borne and other mobile satellite communication systems.
