Gateway Application for LEO/MEO
PALS new 1.8m Q/V-Band earth station antenna designed for communication with LEO and MEO satellite constellations. It has a cassegrain optics and high-speed slewing making it suitable for tracking faster targets. Serves as gateway terminal for feeder and gateway links. A-E-C axis positioner eliminates zenith keyhole effect, enabling uninterrupted tracking during overhead passes.
RF & Mechanical Design
Carbon-fiber composite construction prevents thermal distortion and defocusing. Ultra-precise surface accuracy delivers RF efficiency across standard Ka-band and high-capacity Q/V-band millimeter-wave frequencies, maximizing data capacity of feeder and gateway links. Integrated hub monopulse tracking, embedded controller, and high-precision beacon receiver. Rugged radome with dedicated environmental control system.
Deployment & Integration
Software-guided calibration removes manual field alignment. Reflector installation completed within one day. All electronics, accessories, and RF components are fully integrated within the same hub unit. Modular design enables easy upgrades for future network architectures and frequency expansions.
