Integrated Satellite Attitude Determination & Control System

Combining attitude sensors, actuators, determination and control algorithms on a integrated product, Tensor Tech delivers a total solution to reduce integration time and enable customers to focus on their mission goal.
Moreover, customer support software is provided for functional test, calibration and simulation.

ADCS100 - Integrated ADCS with Reaction Sphere

CubeSat players used to build their satellites via contracting all design and integration jobs to a professional company or build the whole satellite by themselves with purchased components. However, the former method usually costs too much on budget; the latter cannot ensure the system’s reliability and costs too many development times. 

As a result, Tensor Tech proposes this integrated ADCS solution (Attitude Determination & Control System) with affordable prices and user-friendly interfaces. By adopting this offer, you don’t have to program the complicated attitude determination and control algorithms yourself, but enjoy the quick integration process and instant customer support. 

Moreover, a variable-speed, single-gimbal control moment gyro (CMG) driven by spherical motor technology serves as the attitude actuator for this ADCS100. It is comparatively lighter and has less power consumption than traditional solutions.

ADCS10 - Magnetorquer based integrated ADCS

For smaller CubeSats ranging from 1U to 3U, power and volume are limited. In this case, a 3-axis magnetorquer based ADCS is recommended. It fits into users’ requirements and delivers enough performance for solar panel pointing & UHF/VHF antenna. 

Unlike reaction wheel based ADCS that consumes more power, torquer-based ADCS drives with 3-axis magnetorquers, which is the simplest architecture of ADCS. They generate torque via interacting the torquers’ magnetic field with the earth’s. De-tumbling and a rough pointing mode are provided. However, “blind regions” occur while the commanded torque vector is closely vertical to the earth’s magnetic field vector. In these cases, the torquer-based ADCS will have worse pointing accuracy.

To perform the rough pointing functions, GNSS information is required to feed in throughout optional modules or the user’s system. Or, TLE information could work, too. Suppose users’ mission only required simple functions like de-tumbling without the need for sun acquisition, the fine sun sensors could be taken away.

ADCS400 - Pyramid Cluster with Reaction Spheres

For larger CubeSats ranging from 6U to 16U, ADCS needs larger output torque to achieve a certain slew rate and angular momentum storage large enough to prevent quick saturation. Here we recommend users to consider this ADCS400 composing of 4 ADCS100 forming as a pyramid cluster. 

In this case, the reaction sphere can be thought of as a control moment gyro (CMG). The greatest benefit of using CMG as your attitude actuator versus using a reaction wheel is its high torque-to-power ratio. How do they, CMG induces gyroscopic torque while tilting instead of inducing torque via the acceleration/deceleration of the rotor like reaction wheels. In contrast, the control of CMG is less straightforward and requires more complicated steering algorithms. 

However, users don’t have to worry about the complicated control methodologies behind it. This integrated ADCS solution is aimed at providing a user-friendly interface. Simply command the ADCS400 with attitude requirements in every time step, the system will complete the job for you.
