TABLE OF CONTENTS Augmentation systems are a combination of equipment and services that can provide information or capabilities to other systems to enable them to improve their accuracy or performance. GPS augmentation systems provide additional information that can be used by GPS receivers to adjust or improve the accuracy of their measurements.
Augmentation systems gather GPS satellite and atmospheric information at various locations. This information is combined, processed and retransmitted to user devices. The user devices can use this information to adjust their measurements to improve the accuracy of the position information. Various GPS augmentation systems are located throughout the world.
The wide area augmentation system is a network that provides additional information to augment information gathered and calculated by the GPS system. The WAAS provides a satellite signal for WAAS users to assist the routing and approach vectors for aircraft navigation. The FAA provides funding for WAAS.
A WAAS reference station is a fixed point GPS receiver point that has a known location that is used to gather GPS information that can be supplied to the wide area augmentation system (WAAS). The WAAS system gathers and processes the information so it can provide correction information to other GPS and GLONASS receivers.
The European geostationary navigation overlay system is a wide area augmentation system that provides additional information to augment information gathered and calculated by the GPS and GLONASS systems.
