The Settings Area

Updated on Mar 4, 2026

The Route tab will always be present on the section on the right-hand side of the screen. It will, however, change the available settings based on your SatGen 4 variant and the route you have configured. 

Start (UTC): #

This is where you can set the start time and date for the scenario you are creating. 

The earliest date you can use for a scenario is 15 January 1998. Not all constellations will be available at all dates. 

Total Duration and Distance #

Underneath the summary, you will see the total duration and distance calculated for the current route.

Summary #
Map Mode_Route Tab
Waypoints #

The summary of the route includes the following information for each waypoint:

  • Start coordinates
  • Duration
  • Routing mode
  • Speed

Click on the Settings and more button next to a waypoint in the summary to open the information and settings for that waypoint.

You can also click on the relevant point on the map to open these settings.

This will display the waypoint's Latitude and Longitude . It also gives you the ability to set a delay for that point. 

Use the Bin icon in the top right corner to delete a point. 

Use the arrow buttons to navigate to the previous/next waypoint. 

SatGen 4 will also display further information about the route between two waypoints, such as the selected routing mode, the distance between the points, the estimated travel time between the points, the target speed and the apex distance limit.

You can edit the target speed and the apex distance limit and change the set routing mode.
