USE THE CALCULATOR TO DETERMINE THE POINTING ANGLES OF EARTH STATIONS AND TO IDENTIFY WHEN THE SIGNAL OF HISPAMAR SATELLITES WILL BE TEMPORARILY UNAVAILABLE DUE TO SUN INTERFERENCE.

Note:

The calculator program produces estimates exclusively based on geometric angles. It does not consider parameters like RF link margin, antenna depointing, real antenna performance (main and side lobes) or real frequency used, which will affect the duration of sun interference.

It is recommended that an error margin of +/- 10 minutes be used with the times generated by the calculator.
