L/S-Band Tracking Solution

AL-4800 series systems constitute a self-contained elevation-over-azimuth tracking solution for L/S-band links providing high performance under the most demanding operational conditions. The system may be ground-based, transportable, and even shipboard (with additional stabilization) for applications such as satellite imaging, high-altitude flight tests or long-range missile tracking.

The antenna motion system is based on integrated, state-of-the-art, digital servo amplifiers (DSA) providing a simple RS-422 position control and readout interface. The DSA includes all servo loops that control the antenna motion, except for the auto-track loop that is closed via a separate tracking receiver and Antenna Control Unit (Orbit AL-4000). The auto-track function is based on a high-performance E-scan type angle discriminating antenna feed. Supporting different types of antennas, slip rings and rotary joints, the AL-4800 series systems can be adapted for a wide variety of pointing and tracking applications such as long-distance telemetry, LEO satellite TTC, data and video link and processing, optical monitoring and imaging, weather radar and more.
