scenarioAttLocPoint

Overview

Discusses how to use guidance modules to point a particular spacecraft axis towards an Earth fixed location, Boulder in this example. This script sets up a 6-DOF spacecraft which is orbiting the Earth.

The script is found in the folder xmera/examples and executed by using:

python3 scenarioAttLocPoint.py

The simulation uses groundLocation to create an output message with Boulder’s inertial position. This is fed to the 2D pointing module locationPointing which directs the 3rd body axis to point towards Boulder.
