Accuracy and performance of augmentations to global navigation systems outside their areas of coverage

Abstract

Signals broadcasted by Global Positioning System are a good solution for aircraft navigation in remote areas where conventional ground‐based navigation means do not exist. In the world of avionics, more and more navigation guidance systems based on GPS are being developed. Very high claims in terms of accuracy, reliability, and integrity are required for such systems. But GPS alone cannot satisfy these requirements. For this reason, augmentation systems have been designed, which along with GPS receivers form state‐of‐the‐art navigation systems.
