Coast RPO Sequence

The Coast RPO sequence propagates a satellite until it reaches one of three stopping conditions:

  • duration end
  • number of revolutions reaches a limit
  • other conditions (for example, periapsis)

As a default, Astrogator uses the "Earth HPOP Default v10" propagator. You can override this by modifying the propagate segment's propagator.

The following picture shows a coast sequence which free-propagates from an initial position of +500m on the RBar for one revolution:

Sequence parameters

OptionDescription
Coast_DefinitionSelect the mechanism for terminating the coast from a drop-down menu. The options are:
  • Duration
  • Revs
  • Condition
Coast_DurationSpecify the duration of the propagate segment. If Coast_Definition is Duration, you need to enter a value here.
Coast_RevsSpecify the number of revolutions to propagate if Coast_Definition is Revs. Enter as a double.
Coast_ConditionSpecify the orbit event to propagate to if Coast_Definition is Condition. The possible conditions are:
  • Apogee
  • Perigee
  • AscNode
  • DesNode
