This option enables the tracking of and switching between more than one satellite.
There are three main satellites used for APT weather images: NOAA 15, 18 and 19. Each transmits APT on a different frequency, so ideally the software:
- Changes frequency when a satellite becomes visible,
- Updates the rotator information to tracking the satellite,
- Priorities reception if two or more satellites are visible at the same time.
Select Automatic Scheduler from the ribbon bar's Home pane - the Automatic Scheduler pane is displayed. The contents of the pane are initially empty because you haven't defined a scheduler, so click the Schedule button to display the Schedule window.
The Satellites list is populated from the Satellite List in the ribbon bar.
- Refresh - adds new entries.
- Delete - removes selected entries.
- The order in the list is also the priority ranking.
To filter the passes select a minimum pass elevation, for example 10 degrees.
When two or more satellites are visible at the same time the satellite with the highest priority takes precedence. Lower priority passes will be truncated and may even be removed from the list if no longer visible.
Use this option to switch to the next pass before the satellite is visible - this is important if using a rotator as a rotator may typically require up to 60 seconds to change position.
When you select On in the Automatic Schedule window the list is refreshed, showing passes for the previous one hour and next twenty-four hours. In addition, you see the text Auto Schedule ✓ is shown in the main window.
The list is refreshed every hour, so you can leave your system unattended for as long as needed.
