GROUND BASED AUGMENTATION SYSTEM (GBAS)

Abstract

The purpose of this article is to introduce the new technology of Ground Based Augmentation System by taking many factors into consideration such as, what this system is, the system equipment, its operating principle, installation costs, and advantages compared to other systems. Nowadays, many airports are not able to use their capacity adequately due to some disadvantages of approach systems, which is a serious cost for the enterprises. On the other hand, the fact that the number of equipment in the GBAS system is low and the transceiver signals are not influenced by the air traffic around the system ensures the system to be more reliable and preferable in low visibility conditions while reducing the costs greatly.
