Description

The GPS constellation is a custom class that initializes a constellation of GPS Spacecraft for the functionality of the GPS sensor. The purpose of it is to streamline the initialization process of the GPS sensor as a GPS constellation is a primary requirement for its functionality.

NOTE

A GPS constellation is not initialized automatically when a GPS Sensor is initialized but could be initialized for custom constellations.


Example Use Cases

  • Sensor Platform: The GPS constellation is used in this scenario for the functionality of the GPS sensor.

Module Implementation

The requirement for the implementation of this module is a TLE. A TLE with a list of GPS satellites is loaded in and initialized on the simulation system. For each Satellite a GPS transmitter is initialized.


Assumptions/Limitations

  • The constellation is not simulated to the fidelity level of a spacecraft in the simulation due to efficiency
  • The constellations assume a zero-clock bias
