Illumination angle requirement for SatelliteLocation

[Mark2000]

Describe your use case
For optical observation of a satellite with the SatelliteLocation module, it would be beneficial to add optional requirements for illumination angles in the SatelliteLocation module. Some research is needed to see what illumination requirements are common:

• Incidence angle of sun to normal?
• Angle between reflected ray and satellite?
• Glare?

Other Considerations
Should eclipse be handled here or should a separate eclipse model be added to evaluate eclipse status of the observation target.

Shadows are probably too complex to consider here, for now.
