RotatingLibrationPoint.GetDCMAtEpoch(Variable) Method

Top

Description

Returns the direction-cosine-matrix of the RotatingLibrationPoint, representing the instantaneous rotation from the ICRF to the rotating frame.

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.
