European Geostationary Navigation Overlay ServiceThe European Geostationary Navigation Overlay Service (EGNOS) is a satellite-based augmentation system (SBAS) developed by the European Space Agency and Eurocontrol on behalf of the European Commission. Currently, it supplements GPS by reporting on the reliability and accuracy of their positioning data and sending out corrections. The system will supplement Galileo in the future version 3.0.
GNSS augmentationGNSS augmentation is a method of improving the satellite navigation system's attributes, such as precision, reliability, and availability, through the integration of external information into the calculation process. There are many such systems in place, and they are generally named or described based on how the GNSS sensor receives the external information.
GPS-aided GEO augmented navigationThe GPS-aided GEO augmented navigation (GAGAN) is an implementation of a regional satellite-based augmentation system (SBAS) by the Government of India. It is a system to improve the accuracy of a GNSS receiver by providing reference signals.
Local-area augmentation systemThe local-area augmentation system (LAAS) is an all-weather aircraft landing system based on real-time differential correction of the GPS signal. Local GPS reference receivers located at surveyed positions around the airport measure GPS deviations and calculate corrections which are sent to a central location at the airport.

Michibiki Satellite-based Augmentation ServiceMichibiki Satellite-based Augmentation Service (MSAS), formerly Multi-functional Satellite Augmentation System, is a Japanese satellite based augmentation system (SBAS), i.e. a satellite navigation system which supplements the GPS system by reporting (then improving) on the reliability and accuracy of those signals. MSAS is operated by Japan's Ministry of Land, Infrastructure and Transport and Civil Aviation Bureau (JCAB).
Air navigationThe basic principles of air navigation are similar to those of general navigation, involving the planning, recording, and controlling of a craft’s movement from one location to another. In aviation, navigation plays a critical role in ensuring that aircraft operate safely and efficiently within controlled airspace and along designated routes, in accordance with international standards.
International Civil Aviation OrganizationThe International Civil Aviation Organization (ICAO) is a specialized agency of the United Nations that coordinates the principles and techniques of international air navigation, and fosters the planning and development of international air transport to ensure safe and orderly growth. The ICAO headquarters are in the Quartier international de Montréal of Montreal, Quebec, Canada.
Federal Aviation AdministrationThe Federal Aviation Administration (FAA) is a U.S. federal government agency within the U.S. Department of Transportation that regulates civil aviation in the United States and surrounding international waters. Its powers include air traffic control, certification of personnel and aircraft, setting standards for airports, and protection of U.S. assets during the launch or re-entry of commercial space vehicles.
HawaiiHawaii ( hə-WY-ee; Hawaiian: Hawaiʻi [həˈvɐjʔi, həˈwɐjʔi]) is an island state of the United States, in the Pacific Ocean about 2,000 miles (3,200 km) southwest of the U.S. mainland.
North AmericaNorth America is a continent in the Northern and Western hemispheres. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the south and west by the Pacific Ocean. North America covers an area of around 24,709,000 square kilometers (9,540,000 square miles), representing approximately 16.5% of Earth's land area and 4.8% of its total surface area.
Western HemisphereThe Western Hemisphere is the half of the planet Earth that lies west of the Prime Meridian and east of the 180th meridian. The other half is called the Eastern Hemisphere. In the United States, the term "Western Hemisphere" is often used as a metonym for the Americas, even though geographically, the hemisphere also includes parts of other continents.*As an Amazon Associate I earn from qualifying purchases.
