Description

Translates the position and rate vectors from this system into the output system.

Syntax

Parameters

Epoch
Specify an epoch.
OutputSystem
Specify an output system.
PositionInMySystem
A position vector to be transformed from this system to the output system.
VelocityInMySystem
Specify a velocity vector to be transformed from this system to the output system.

Remarks

Consider a point moving along its trajectory in space. The point's position and velocity can be given at some specified time using Cartesian coordinates in one of VGT coordinate systems. The same point at the same time will have different Cartesian coordinates with respect to a different VGT coordinate system. One set of coordinates can be obtained from the other using Transform methods defined for VGT coordinate systems: given time and coordinates with respect to one VGT coordinate system, these methods output coordinates with respect to another system. For example, consider a center point of a satellite. Its location in low Earth orbit can be given using Cartesian coordinates with respect to the ECEF coordinate system (\"ECEF\" means \"Earth Centered Earth Fixed\"). The same location is significantly farther away from the center of the Moon so its Cartesian coordinates in the Moon Centered Moon Fixed coordinate system will reflect a much greater distance from the Moon center.
