Default Scenario Satellites

As of spring 2015, the default GPS constellation consists of the following active satellites:

  • 3 x Block IIA satellites
  • 12 x Block IIR satelliets
  • 7 x Block IIR-M satellites
  • 10 x Block IIF satellites

GSG uses this constellation as the default for its scenarios. You can, however, change this when developing or manipulating scenarios, e.g., to simulate an event in the past.

The following illustration shows the Constellation Editor window with the default satellite types.
The window can be accessed in Studioview, via the Tools menu > Scenario Editor > Signals tab > Edit GPS constellation… button:

GLONASS Default Satellite Types

All satellites default to the GLONASS-M type. Alternatively, you can select GLONASS K1.
