AL-4048D - ORBIT Communication Systems

AL-4049-1D EL/AZ

Heavy-Duty, High Quality, Telemetry Tracking Positioner

The AL-4049-1D, Elevation over Azimuth Antenna Positioner, is designed to support large antennas (7.0-11.0 m in diameter). Accordingly, it is well-equipped to meet the demanding requirements of applications such as longer range aeronautical telemetry tests, tracking of LEO (Low Earth Orbit) satellites for high resolution earth observation missions and tracking of MEO (Medium Earth Orbit) satellites for navigation applications. The AL-4049-1D is also suitable for tracking GEO (Geostationary Earth Orbit) satellites (for the higher bands such as Ka and above).
The AL-4049-1D model is a high performance pedestal, which is reflected in the “ZERO” backlash, high orthogonality (up to 0.02º) and high encoder accuracy (0.02º RMS).

Key Features

  • Elevation Over Azimuth axes configuration (stabilization is optional)
  • Four high power, digital servo amplifiers to control antenna motion
  • Dual drive, zero backlash enabling high torque and stability
  • Brushless motor and planetary gear assembly
  • Modular & easily maintainable
