Note that the time is given in a standard form using the AM or PM reference. Pass - This value provides an indication of how long the sighting will last. Note that this is the maximum elevation of the sighting - not the pass itself. This value provides the genreal elevation and direction to look where the sighting will begin. The approach is broken into two parameters - the elevation and the azimuth.
Elevation is the angle between the satellite and the horizon and azimuth is the direction to look.
Departure - Similer to Approach, but this value is where the sighting will end.
