Advanced Deployment Testing System for Satellite Solar Arrays
UTEC Industrial engineered and built deployment testing harnesses for Maxar Technologies (Space Systems Loral), enabling validation of satellite solar wing deployment under simulated space conditions.
Project Overview
Satellite solar arrays must deploy flawlessly in orbit — there are no second chances. Before launch, every solar wing undergoes rigorous ground-based deployment testing to verify that panels unfold correctly, locks engage properly, and structural integrity holds under the stresses of deployment. UTEC Industrial designed and fabricated the Mechanical Ground Support Equipment (MGSE) that makes this testing possible.
The deployment testing harnesses built by UTEC simulate the conditions a satellite solar wing experiences during deployment in space. Testing takes place inside thermal vacuum chambers that replicate the vacuum of space and the extreme temperature swings between direct sunlight and shadow. Gravity offload systems counteract Earth's gravitational pull, allowing the solar wings to deploy as they would in a zero-gravity environment.
These systems are critical to mission success. A failed solar array deployment can render a satellite inoperable, resulting in the loss of hundreds of millions of dollars in hardware and the mission objectives it supports. UTEC's precision engineering ensures that every deployment sequence is validated before the satellite ever leaves the ground.
UTEC's Role
UTEC provided end-to-end engineering, CNC machining, and fabrication for the deployment testing harnesses. The work included designing custom fixtures and support structures capable of precisely positioning satellite solar wings during deployment sequences. UTEC's team engineered gravity offload mechanisms that allow the massive solar arrays to move freely during testing, as if in microgravity.
All components were machined to tight tolerances to meet the demanding accuracy requirements of satellite-grade ground support equipment. UTEC also coordinated closely with Maxar Technologies' engineering teams to ensure seamless integration with their thermal vacuum chamber infrastructure and testing protocols.
