CelestialObject.GetSpinRateAtEpoch(Variable) Method

Top

Description

Returns the instantaneous spin rate about the angular velocity vector. Note that a positive spin rate indicates a counter-clockwise rotation as viewed from the z-axis of the ICRF; a negative spin rate indicates a clockwise rotation as viewed from the z-axis of the ICRF, eg. for Venus.

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.
