{Position}

These Position attributes define Launch or Burnout position for a Launch segment of the MCS.

Syntax

Astrogator <Satellite Object Path> SetValue <Astrogator Object Path>.{DisplaySystem}.{Position Attribute} <Value> <Unit>

Description

The following position attributes are available:

Position Attribute Description
Latitude Specifies the latitude of the launch or burnout location.
Longitude Specifies the longitude of the launch or burnout location.
Radius / Altitude Specifies the radius (for planetocentric) or altitude (for planetodetic) of the launch or burnout location
LaunchAz Specifies the launch azimuth of the burnout location (not valid for launch)
DownrangeDistance Specifies the downrange distance of the burnout location (not valid for launch)
