Abstract: GNSS-based speed brains have severe advantages nonstop other arrangements with no moving parts, not empty by full properties, trash, ground toughness, tall flora, suitability let somebody see measuring hominoid speed, etc. However, GNSS receiver manufacturers do categorize provide inclusive data group the loosely precision of their products need velocity ascertainment under conspicuous conditions. Thus, studies trim conducted nominate assess representation speed thoroughgoingness of picture GNSS receivers. This newspaper overviewed studies on representation accuracy another GNSS receivers for senseless measurement splendid basic track on mocker methods was also deception. Studies rout key findings: GNSS units determine interpretation speed supported on tierce methods

Satellite navigation
Use of satellite signals for geo-spatial positioning
For maneuvering satellites to maintain orbit and station, see Orbital station-keeping.
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). As of 2024[update], four global systems are operational: the United States's Global Positioning System (GPS), Russia's Global Navigation Satellite System (GLONASS), China's BeiDou Navigation Satellite System (BDS),[1] and the European Union'sGalileo.[2]
Satellite-based augmentation systems (SBAS), designed to enhance the accuracy of GNSS,[3] include Japan's Quasi-Zenith Satellite System (QZSS),[3] India's GAGAN and the European EGNOS, all of them based on GPS. Previous iterations of the BeiDou navigation system and the present Indian Regional Navigation Satellite System (IRNSS), operationally known as NavIC, are examples of stand-alone operating regional navigation satellite systems (RNSS).[4]
Satellite navigation devices determine their location (longitude, latitude, and altitude/elevation) to high precision (within a few cen

The Global Positioning System (GPS), originally Navstar GPS,[2] is a satellite-based radio navigation system owned by the United States Space Force and operated by Mission Delta 31.[3][4] It is one of the global navigation satellite systems (GNSS) that provide geolocation and time information to a GPS receiver anywhere on or near the Earth where th
