AL-4800 Series - ORBIT Communication Systems

AL-4800 Series

L/S/C – Band Tracking System

AL-4800 series systems constitute a self-contained elevation-over-azimuth tracking solution for L/S/C-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 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 and TT&C, weather radar and more.
