Notice:

Do not forget to do the [Auto ground clutter mapping] after changed value of the [Origin EL position offset
correction]. (Refer to the “Operator’s manual” for operation)

5.3.6. Conclusion

Calculation of the solar position:
This software uses “Astronomical algorithms” created by Jean Meeus to calculate algorithms of the
solar position.
The  accuracy  of  this  algorithm  on  longitude  is  +/-  72  degrees  of  range  within  0.0167  degrees.
However  accuracy  depends  on  atmospheric  temperature,  pressure,  and  humidity.  Therefore  under
certain circumstances accuracy may be very poor.
Currently the solar azimuth value is properly corrected when refraction of atmospheric conditions are
properly considered.
