Things you should be aware of

Space is hard. That’s why we should do the system engineering job well and separate works into different professional sectors. To help you achieve your goal faster, Tensor Tech not only supplies your components and systems, but we are also your consultant and total solution provider.

As a result, you don’t have to go through every complicated technical detail about attitude control by yourselves. Let professional companies like us help. However, you should still have some fundamental knowledge while selecting the “fit” product and service for your missions.

A sun sensor is a device that senses the direction of the incident angle of lights. The source of lights is usually the sun. Therefore, we called it the “sun sensor.” There are various types of sun sensors that differ in their characteristics. However, two classifications are the most commonly used, coarse sun sensor and fine sun sensor. Fine sun sensors can also be classified into two types, analog output fine sun sensor and digital output fine sun sensor. The output signal from the coarse sun sensor varied if the sun is entering/leaving its field of view (FOV) or changing its position in the FOV. It often contains a single photoresistor […]

The inaccuracy of the satellite’s moment of inertia will cause errors in controlling the satellite’s attitude control system and further affect the satellite’s attitude. Regardless of the size and mission of a satellite, the two most important factors affecting attitude control are the moment of inertia and centroid. For SmallSat, it is difficult for external moments to change their attitudes because of their greater inertia, but for CubeSat, external moments may cause attitude changes. In actual situations, temperature changes will cause the deformation of the satellite. Because different materials have different expansion coefficients […]

In the world of engineering, we know there is no “best” solution, but only the “most suitable” solution. That’s why people used to build their own ADCS by customize space components or sometimes even develop their own attitude determination & control components. However, as the space-agency-driven time has passed, the commercial players are now aiming for COTS (Commercial-Off-The-Shelf) attitude determination and control components. Even an integrated ADCS solution is available right now for shortening its mission development time and costs. Therefore, we need to understand the specifications, pros & cons of these components & systems for a better comparison. Here are the suggested steps you could follow […]
