Description
Converts the position and velocity specified by fromVector from the fromSystem coordinate system to the toSystem coordinate system, referencing the coordinate systems to the specified epoch.
Timing Precision Mode
This page describes functionality in millisecond timing precision mode. Millisecond timing precision mode is deprecated and will be removed in a future release. We recommend that you migrate your Mission Plans to nanosecond timing precision mode.
Function Signature
Arguments
fromSystem |
|||||||||||||||||||||||||||||||||||||||||
Description: |
Coordinate system of input position and velocity. |

Description: |
Coordinate system of output position and velocity. |

epoch |
|
Description: |
The TAI epoch of the input and/or output position and velocity in modified Julian date format. If both the input and output coordinate systems are referenced to an epoch, both will be defined using this epoch. |
fromVector |
|
Description: |
A six-element array containing the position and velocity in the input coordinate system. |
Required Size: |
At least 6 |
Return Value
Type: |
Array of number (size = 6) |
Returns a six-element array containing the position and velocity in the output coordinate system.
Syntax
myArray1 = PositionVelocityConvert(myVariable1, myVariable2, myVariable3, myArray2); |
This example converts the position and velocity of Spacecraft1 from ICRF to the Earth-Fixed frame. This shows two different approaches to setting the EarthFixPosVel array. The output will be the same using any of these approaches; each option is available in order to provide flexibility in the way users can construct their script.
Output:
