Propagator





Description

Returns whether the specified look ahead propagator is supported

Syntax

[Visual Basic .NET]
Public Function IsLookAheadPropagatorSupported( _
   ByVal Propagator As AgELookAheadPropagator _
) As Boolean

[C#]
public bool IsLookAheadPropagatorSupported(
AgELookAheadPropagator Propagator
);

[Managed C++]
public: bool IsLookAheadPropagatorSupported(
AgELookAheadPropagator Propagator
);

[Java]
public bool isLookAheadPropagatorSupported(
AgELookAheadPropagator Propagator
);

[Unmanaged C++]
public: HRESULT IsLookAheadPropagatorSupported(
AgELookAheadPropagator Propagator,
VARIANT_BOOL * ReturnValue
);

Parameters

Propagator
Member Value Description
eLookAheadUnknown -1 Reserved for look ahead propagators that are not currently supported
eLookAheadHoldCBIPosition 0 The HoldCBIPosition look ahead propagator keeps position and velocity constant in the inertial (i.e., CBI) frame.
eLookAheadHoldCBFPosition 1 The HoldCBFPosition look ahead propagator keeps position and velocity constant in the fixed (i.e., CBF) frame.
eLookAheadTwoBody 2 Two-Body is an analytical propagator that generates ephemeris by evaluating a formula.
eLookAheadJ2Perturbation 3 The J2 Perturbation (first-order) propagator accounts for secular variations in the orbit elements due to Earth oblateness.
eLookAheadJ4Perturbation 4 The J4 Perturbation (second-order) propagator accounts for secular variations in the orbit elements due to Earth oblateness.
eLookAheadDeadReckon 5 The DeadReckon look ahead propagator projects the motion of the vehicle along a straight line, along the last velocity vector.
eLookAheadBallistic 6 The Ballistic Propagator defines an elliptical path that begins and ends at the Earth's surface. Specifying a fixed flight time, initial velocity or altitude can further refine the shape of the trajectory.
