Satellite Test Positioner for Anechoic Test Chambers
UTEC Industrial developed, built, and installed precision satellite test positioners for RTX (Raytheon), enabling full rotational movement for testing antennas, sensors, and communication arrays inside anechoic chambers.
Project Overview
Anechoic test chambers are specialized rooms lined with electromagnetic-absorbing materials that eliminate signal reflections, creating a controlled environment for testing satellite antennas, sensors, and communication systems. Inside these chambers, satellites must be precisely positioned and rotated to measure their electromagnetic characteristics from every angle.
UTEC Industrial engineered and manufactured satellite test positioners that serve as the mechanical foundation for this testing. These precision platforms maneuver full-size satellites within the chamber, providing controlled rotational movement across multiple axes so that engineers can characterize antenna patterns, verify sensor performance, and validate communication array functionality.
The positioners must achieve exceptional accuracy while supporting the full weight of a satellite. Any mechanical vibration, backlash, or positioning error would corrupt the test data, making precision engineering and fabrication essential to the system's success.
UTEC's Role
UTEC handled the complete development cycle for the satellite test positioners — from initial engineering and 3D modeling through CNC machining, fabrication, assembly, and on-site installation. The positioners required extremely tight machining tolerances to achieve the sub-degree positioning accuracy demanded by electromagnetic testing protocols.
UTEC's engineers designed the drive systems and structural components to minimize vibration and ensure smooth, repeatable motion under heavy satellite loads. The team also managed installation and commissioning at the RTX facility, verifying that all performance specifications were met in the actual anechoic chamber environment.
