Tensor Tech's ADCS100 is a integrated Reaction Sphere ADCS for CubeSats ranging from 1.5U, 2U, 3U, to 6U. This sub-system combines 6 FSS100, 1 RS100, and a tactical grade gyroscope, to provide a pointing accuracy up to 0.2 deg when the sun is capturable and 1 deg when it is not. A GPS module can increase the attitude determination better.
Hardware Included with ADCS 100:
- 6 Fine Sun Sensors
- 1 Tactical Grade Gyro
- 1 Spherical Motor
One Reaction Sphere can achieve same function in 1/3 volume, cost, weight and, power consumption. Tensor Tech's RS100 is a Reaction Sphere designed for CubeSats ranging from 1.5U, 2U, 3U, to 6U. This motor functioning like a Single-Gimbal Control Moment Gyro in terms of rotational dynamics; and actuated by spherical motor technology. With this device, you can control the orientation of your CubeSat like 3 or 4 traditional single-axis reaction wheel did. However, the weight, size, and power consumption is lower.
Reaction Sphere Specs:
- Max. Momentum: 10mNms
- Max. Torque: 1mNm
- Power Consumption: <1W
- Weight: <400g
- For the ADCS100, customer's OBC simply input an attitude command with a specific reference frame; For RS100, the OBC may treat it as a torque output unit and input with 3-axis torque command. The closed-loop control and auto-desaturation mechanism with magnetorquers are embedded in.
Tensor Tech's FSS100 is a nano fine sun sensor for CubeSats. This device sensing the direction of sunlight in two vectors and provide pointing knowledge up to 0.2 deg.
Fine Sun Sensor Specs:
- Pointing Knowledge: 0.1 deg (3-sigma), no albedo
- Current Consumed: <5mA
- Interface: I2C
