Ephemeris.GetCovarianceData(Variable, Variable) Method

Top

Description

Gets the covariance matrix from the ephemeris at the specified vector. Which value is returned for discontinuous columns is specified by the second argument. If the Ephemeris does not contain covariance data, an error is thrown.

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.
