The Compact SOTM Solution for Mobile Missions
The POMA-45 is a compact SATCOM-On-The-Move (SOTM) antenna system for land platforms. It delivers seamless, real-time Ku- and Ka-band satellite connectivity for mission-critical voice, video, and data, keeping mobile command, emergency response, and broadcast teams connected from any vehicle, on any terrain.
Advanced Engineering in a Minimal Footprint
Brushless DC servo motors with a precision gear train provide accurate, low-backlash pointing, while the cap-type feed delivers high efficiency and low sidelobes. All models support dual-band Ku/Ka operation with no hardware change, maximizing versatility and performance in an ultra-compact form factor.
Autonomous, Secure, and Simple Operation
The POMA-45 is fully self-contained and does not depend on GPS for tracking: advanced beacon tracking continuously corrects gyro drift, making it suitable for GPS-denied environments. After a one-time entry of the platform position, it acquires and tracks the satellite fully automatically while on the move.
