Spacecraft.TCA Method

Top 

Description

Returns the epoch for the time of closest approach (TCA) between two objects. This method returns the local extrema and is more precise if used after narrowing down your closest approaches using the Spacecraft.CloseApproachRange() method.

 

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.
