Detailed Description
Implements a single axis sun sensor.
The output is gray code, sine, cosine and bias voltages. It also outputs the mission elapsed time of the transit of the sun through the field-of-view of the sensor. The sun angle is also available as an output. No lags are modeled and the sensor is noise free. Reference: Wertz, J., Ed., Spacecraft Attitude Determination and Control. Single axis sun sensor with no lag or noise.
