Satellite navigation

system of satellites that provide autonomous geo-spatial positioning with global coverage

Garmin Ltd. is an American multinational technology company based in Olathe, Kansas. The company designs, develops, manufactures, markets, and distributes GPS-enabled products and other navigation, communication, sensor-based, and information products to the automotive, aviation, marine, outdoors, and sport markets.

TomTom is a Dutch multinational developer and creator of location technology and consumer electronics. Founded in 1991 and headquartered in Amsterdam, TomTom released its first generation of satellite navigation devices to market in 2004. As of 2019, the company has over 4,500 employees worldwide and operations in 29 countries throughout Europe, Asia-Pacific, and the Americas.

In modern terms, it most often refers to coordinates which specify one's position on the globe at the end of each "leg" (stage) of a journey.

Propagation of error with varying topology

In the field of geodesy, Receiver Independent Exchange Format (RINEX) is a data interchange format for raw satellite navigation system data. This allows the user to post-process the received data to produce a more accurate result — usually with other data unknown to the original receiver, such as better models of the atmospheric conditions at time of measurement.

The pseudorange (from pseudo- and range) is the pseudo distance between a satellite and a navigation satellite receiver (see GNSS positioning calculation), for instance Global Positioning System (GPS) receivers.

Pseudolites are most often small transceivers that are used to create a local, ground-based Global Positioning System (GPS) alternative. The range of each transceiver's signal is dependent on the power available to the unit.
