Satellite Template

This set of four Python scripts model a basic satellite. Its main functions are to propagate an orbit from Two-Line Elements, check if a point on Earth is within a set field of regard, and see if a ground station is viewable. You can find these files within the examples/application_templates/satellite_template folder after you clone the GitHub repository.

Maintaining the current file structure, with main_sat.py and satellite.py in the top-level folder, and schemas.py and config.py in the satellite_config_files folder will allow it to run without any changes. This architecture (seen in a diagram below) is not the only way to model a satellite in NOS-T, but has worked well for the development team. The black boxes with sharp edges denote the data being pulled in by the main_sat.py entry point code.

Please note that this template is built as a managed application - meaning that it responds to control events (red box with sharp edges in the above figure) from the included NOS-T Manager application. These include events which initialize, start up, and maintain consistent timing throughout the test case. An in-depth description of the Manager commands is found here.
