Highlights
20 kg total opens satellite broadband to UAVs, airships and light aircraft — pair it with our long-endurance drone platforms.
POE interface joins the aircraft network and power system; high-precision attitude fusion handles the platform’s motion.
Salt-fog, humidity, thermal cycling and low-pressure adaptation for aviation environments.
Applications
UAV & airship platforms · Fixed and rotorcraft broadband · Airborne command relays · Maritime-air patrol aircraft
Airborne SATCOM — Compare Two Terminals
| Model | Aperture | Stabilization | Weight | Best for |
|---|---|---|---|---|
| Airborne COTM 0.45 m | 0.45 m flat horn | ≥100°/s slew rates | 20 kg all-in | High-dynamic aircraft and larger UAVs |
| Airborne Lite 0.35 m | 0.35 m carbon | 3-axis, 360° unlimited | ≤6.5 kg incl. modem | Weight-critical UAVs |

How to Choose in This Family
- Aircraft class. The 20 kg / 100°/s COTM unit tracks through aggressive maneuvers; sub-6.5 kg Lite opens smaller airframes.
- Ku or Ka. Both offer band options — match the constellation your service plan uses.
- Install surface. The Lite's φ410 mm footprint fits most UAV payload bays; the COTM pod needs a structured mount.
Where this model sits: Airborne COTM 0.45 m is High-dynamic aircraft and larger UAVs.

FAQ
Can it fly on a UAV?
Yes — 20 kg total weight and a φ720×245 mm outline are sized for large UAVs and airships; see our long-endurance UAV platforms for matched airframes.
How does it keep the satellite during maneuvers?
High-precision attitude measurement with platform-motion compensation steers the beam through climbs, banks and rotations (≥100°/s azimuth slew).
What about pressurization and spray?
IP66 sealing with salt-fog, humidity, thermal and low-pressure adaptation (manufacturer specification).
