A spacecraft can estimate the attitude state by comparing external measurements from attitude sensors with reference information. CubeSats tend to use 4-quadrant analog solar sensors which have the ...

Recently, I’ve been working on a solar off-grid monitoring system. In the system are a few split-core Hall effect sensors to monitor DC current in the solar panel current, the battery charge current, ...

Over time, the performance of optical isolators or sensors can degrade. But a simple auto-calibration circuit will account for changes in LED and sensor characteristics to keep optical devices running ...

Authors first explains the calibration process of sun sensor based on cubic surface fitting. The calibration and testing platform of the sun sensor includes a solar simulation light source, ...
