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.
