POMA-45N-MIL SOTM

The POMA-45N SOTM (Satcom-On-The-Move) antenna supports both Ku- and Ka-band operations. It features a highly reliable direct-drive mechanism for azimuth (AZ) and elevation (EL), along with a cap-design feed for enhanced efficiency and reduced side lobes.

The POMA-45N operates independently of GPS by using satellite beacon tracking to correct gyro drift, requiring only manual input of local latitude and longitude during initial satellite acquisition. It offers rapid pointing, with GPS/BeiDou cold start positioning in under 80 seconds, and hot start or manual input in under 60 seconds.

Ideal for a wide range of mobile applications, the POMA-45N delivers dependable real-time communications for military operations, stable links for emergency response, and high-quality live broadcasting. It also ensures secure corporate network connectivity and consistent satellite communication for maritime and aviation use, maintaining performance across varied terrains and weather conditions.

Key Features

• Available in Ku and Ka Band
• High Tracking Accuracy, th e Tracking error <0.5 dB RMS without blockage
• Good Tracking Stability, the AZ system uses a closed-loop stabilization algorithm for precise satellite tracking, even during fast movements or “S” travel.
• Blockage recovery in under 3 seconds for blockage times under 5 minutes; recovery in under 5 seconds for blockage times under 20 minutes
• Dynamic Pointing and Switching enables real-time satellite pointing and seamless satellite switching while in motion.
