The Tensor Tech ADCS Testbed is an Attitude Determination and Control System (ADCS) testbed used for the examination and calibration of ADCS.

The testbed consists of an air-bearing platform, a triaxial Helmholtz cage, and a solar simulator. By placing the user's ADCS on top of the testbed, the user may perform the functional test on each mode of the ADCS.

The functional test is critical for users who are developing their ADCS algorithms. Troubleshooting and debugging can be performed using this testbed.

The fully scalable testbed can also measure the mass properties of the device under test. By placing the whole satellite on top of the testbed, the user may measure the spacecraft's mass properties for different settings on the ADCS.

This test procedure is crucial to extract the optimal performance of the ADCS and avoid unexpected outcomes in orbit.

The video below is a presentation by Tensor Tech from the 2021 satsearch webinar: "a guide to selecting an ADCS for a small satellite mission". For more information about the webinar, and to see footage of the entire event, please click here

Key features

  • A spherical air bearing platform, made with non-magnetic materials, to simulate 3DOF motion in space
  • A 3-axis magnetic cage to simulate Earth's magnetic field in space
  • Sunlight source and darkroom to simulate sun in space
  • The system utilizes a "hardware in the loop" setup
  • A 3-axis Helmholtz Cage with jigs included for co-working with the platform


The air bearing platform includes the spherical air bearing, attitude measurement unit, and necessary jigs for conducting experiments. The following items are optional enhancements for application-specific analysis:

  • Air Bearing Platform
  • 3-axis Helmholtz Cage
  • Solar Simulator
  • Mass properties measurement software
