GNSS augmentation

Augmentation of a global navigation satellite system (GNSS) is a method of improving the 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.

Satellite navigation

A satellite navigation or satnav system is a system that uses satellites to provide autonomous geopositioning. A satellite navigation system with global coverage is termed global navigation satellite system (GNSS). , four global systems are operational: the United States' Global Positioning System (GPS), Russia's Global Navigation Satellite System (GLONASS), China's BeiDou Navigation Satellite System, and the European Union's Galileo.

Ground segment

A ground segment consists of all the ground-based elements of a space system used by operators and support personnel, as opposed to the space segment and user segment. The ground segment enables management of a spacecraft, and distribution of payload data and telemetry among interested parties on the ground.

Global Positioning System

The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radio navigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.

Swisstopo

Swisstopo is the official name for the Swiss Federal Office of Topography (in German: Bundesamt für Landestopografie; French: Office fédéral de topographie; Italian: Ufficio federale di topografia; Romansh: Uffizi federal da topografia), Switzerland's national mapping agency. The current name was made official in 2002. It had been in use as the domain name for the institute's homepage, swisstopo.ch, since 1997. The main class of products produced by Swisstopo are topographical maps on seven different scales.
