Hello,
I am working with Gmat python API and need to set up contact locator events
between a satellite and a ground segment.
here is my code
gaindesat = gmat.Construct("Spacecraft", "Gaindesat")
gaindesat.SetField("DateFormat", "UTCGregorian")
gaindesat.SetField("Epoch", "15 Jul 2024 21:00:00.000")
gaindesat.SetField("CoordinateSystem", "EarthMJ2000Eq")
gaindesat.SetField("DisplayStateType", "Keplerian")
gaindesat.SetField("SMA", 7800)
gaindesat.SetField("ECC", 0.00001)
gaindesat.SetField("INC", 98.5)
gaindesat.SetField("RAAN", 75)
gaindesat.SetField("AOP", 90)
gaindesat.SetField("TA", 85)
gaindesat.SetField("DryMass", 0.998)
gaindesat.SetField("Cd", 2.2)
gaindesat.SetField("Cr", 1.5)
gaindesat.SetField("DragArea", 0.015)
gaindesat.SetField("SRPArea", 0.015)
grds = gmat.Construct("GroundStation", "ControlCenter")
grds.SetField("StateType", "Spherical")
grds.SetField("HorizonReference", "Ellipsoid")
grds.SetField("Location1", 14.727500)
grds.SetField("Location2", -1719258)
grds.SetField("Location3", 0.008)
grds.SetField("Id", "12F")
accessevents = gmat.Construct("ContactLocator", "myContactLocator")
accessevents.SetField("Target", gaindesat.GetName())
accessevents.SetField("Observers", grds.GetName())
#accessevents.SetField("OccultingBodies", "Earth, Moon")
accessevents.SetField("InputEpochFormat", "UTCGregorian")
accessevents.SetField("InitialEpoch", "15 Jul 2024 21:00:00.000")
accessevents.SetField("FinalEpoch", "16 Jul 2024 21:00:00.000")
accessevents.SetField("IntervalStepSize", 10)
accessevents.help() show me target and observers are set but when i run
gmat.Initialize i have this error as output error setting observers on
ContactLocator myContactLocator. All observers must be either ground
stations or spacecraft.
Still gmat.ShowObjects("GroundStation") give me ControlCenter as about.
Does someone have the solution or face the same problem
Best regard
