Earth Observation & LEO/MEO Tracking
PALS designed new 3.7m antenna for Earth Observation and TT&C application with simultaneous S and X-Band reception-transmission and Ka-Band reception. Serves as high-performance data reception and processing terminal for LEO and MEO satellites constellations. X/Y positioner enables full hemispherical coverage with no zenith keyhole, ensuring uninterrupted tracking during overhead passes. Excellent G/T and sidelobe performance optimizes link budget for fast connectivity.
RF & Mechanical Design
Tri-band operation with carbon-fiber composite construction preventing thermal distortion. Remote-control interface with NMS Vision provides seamless integration into ground networks. Integrated hub design houses all electronics and RF components within a single compact unit.
Reliability & Integration
Optimized reliability using most modern industrial components available. Remote-control interface ensures seamless ground network integration. All electronics and RF components fully integrated within the unit. Modular design supports future upgrades and frequency expansions.
