Tensor Tech ADCS100 – Integrated ADCS with Reaction Sphere


This Satellite Attitude Determination and Control System is designed for CubeSats ranging from 1.5U, 2U, 3U, to 6U. A full set of attitude determination / actuator hardware and firmware is embedded. This sub-system combines 6 Fine sun sensors (FSS100 from Tensor Tech), 1 reaction sphere (RS100 from Tensor Tech), and a tactical grade gyroscope, to provide a pointing accuracy up to 0.2 deg (3-sigma) when the sun is capturable and 1 deg (3-sigma) when it is not. A GPS module can increase the attitude determination precision.

Spherical Motor Technology

Unlike traditional single-axis reaction wheel motor, 1 spherical motor is capable of providing angular momentum in 3 axes. In addition, by appling bias currents, it acts as 3 single-axis magnetorquers as well. In terms of rotational dynamics, it is actually a control moment gyro. While the algorithms including:

  1. De-tumbling
  2.  Attitude Sensor Calibration
  3.  Attitude Determination to
  4.  3-axis Pointing Control

All are embedded in our controller, all you need to do is giving attitude command from satellite OBC via I2C or UART in a standard PC104 port.
