The SOTM type POMA-40 supports Ku, Ka band HTS and GEO satellite operations. Its design integrates the high-efficiency parabolic feed network, low noise amplifier, servo control modeule GPS positioning module and intelligent tracking structure into the same antenna, which enables the unmanned platform to perform remote control through satellites in dynamic motion, real-time video transmission, IP call and broadband internet access.
This antenna operates independently of GPS by using satellite beacon tracking to correct gyro errors, requiring only manual input of local latitude and longitude before initial satellite pointing. It offers rapid initial satellite pointing, with GPS/BD cold start positioning in under 80 seconds and hot start (or manual input) in under 60 seconds.
The POMA-40 SOTM terminal is widely deployed on military mobile platforms to enhance combat effectiveness, and serves as a vital asset for emergency response units—including police, fire, and medical services—providing reliable communications for disaster relief and crisis management.
- Available in Ku, Ka Bands and operates HTS and GEO
- High Tracking Accuracy, the tracking error <0.5 dB (RMS) without blockage
- Perfect Tracking Stability; the AZ adopts loop stability alghoritm, for precise satellite tracking, even during fast movements or "S" travel
- Use 2-axes stability, 3-axes tracking system
- Fast Sheltering Recovery Time; the blockage tine <5min, recovery time <3s
- Convenient Maintenance; modular design, simple interface specification and convenient fault diagnosis and maintenance
- 4G / 5G / LTE supported modem for load balancing and bonding solutions OPTIONAL
