Determining usability of a navigation augmentation system

摘要

In one aspect, the invention is the system for assessing a navigation augmentation environment. The system includes a reference station for receiving messages from a satellite. The reference station has a known position. The system also includes a simulator for simulating an augmentation system by determining corrections based on the messages received and the known position of the reference station. The system further includes a monitoring system to render the corrections to a user in a form enabling determination of the usability of the augmentation system in the navigation augmentation environment.
