What is Global Navigation Satellite System (GNSS)? | Understanding GPS and Augmentation Systems

Hello. In this video we look at what is meant by Global Navigation Satellite System or GNSS. Satellite Navigation plays a major role in Aircraft navigation currently and is used by all major aircraft. This concept becomes important for PBN to allow a more direct routing and hence more fuel savings.


We look at the 2 components of GNSS: GPS and Augmentation Systems. We see what is meant by GPS and how it functions and also how an aircraft computes its location and time. We also look at the types of augmentation systems, and focus particularly on Aircraft Based Augmentation System.
