Turning Head Antennas
Our turning head antenna (THA) systems, often simpler and smaller than full-motion systems, are commonly used in satellite communication applications that do not require continuous, real-time tracking but still benefit from flexible orientation.
These systems rotate on a single axis (often azimuth) and typically tilt within a limited range (elevation), making them suitable for stationary or semi-fixed applications that need periodic repositioning rather than active, full-motion tracking.
THA Key Features
- Dimension range:
[7,5 m … 13,0 m]
- Frequency bands:
[S, C, X, Ku, Ka]
- Feed system:

Key Applications
Fixed Satellite Communication Stations
Turning head antennas are widely used in ground stations communicating with satellites in geostationary orbit (GEO). Since GEO satellites remain fixed relative to the Earth’s surface, these antennas only need to be adjusted occasionally, making them more cost-effective for such applications. This setup is ideal for broadcasting, telecommunication, and internet service providers who need consistent satellite alignment without active, dynamic tracking.
Low and Medium Earth Orbit Satellite Support
While not typically used for continuous LEO and MEO tracking, turning head antennas can periodically reposition to establish connections with satellites passing overhead. This intermittent tracking is useful for data collection from Earth observation, remote sensing or scientific satellites during their passes, especially in applications that do not require continuous connectivity.
IoT and M2M (Machine-to-Machine) Communication
Turning head antennas are commonly used for IoT applications, especially in industrial sectors like energy, agriculture, and transportation, where low-data-rate periodic communication with satellites is sufficient. The antenna adjusts periodically to connect with passing satellites, transmitting telemetry or IoT data on intervals, making it cost-effective for wide-scale intermittent communication.
Disaster Recovery and Emergency Communication
During disasters, a turning head antenna system provides a rapid-deployment solution for satellite communication. Its simplicity and ease of setup make it ideal for emergency responders who need to establish temporary communication links with GEO satellites. The system offers vital connectivity for voice, video, and data transfer in areas where terrestrial networks have been damaged or are unavailable.
Fixed Maritime and Remote Location Communication
While full-motion antennas are often necessary for mobile applications, fixed maritime and remote sites benefit from turning head antennas when tracking GEO satellites for high-speed broadband connectivity. For instance, stationary offshore rigs or remote camps use turning head antennas to maintain reliable satellite connections for crew communications, monitoring, and internet services.
