Spacecraft.GetLaunchAsymptoteDeclination(Variable) Method

Top

Description

Returns the declination of the launch asymptote (DLA). The DLA is the latitude of the outbound hyperbolic asymptote referenced to the chosen coordinate frame. This value is only valid for hyperbolic cases (e > 1), it is invalid for elliptical orbits (e < 1) and will report an error. The reference frame will be evaluated at the Spacecraft's 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.
