While these developments have made satellite-based geodetic network surveying more flexible and cost effective than its terrestrial equivalent for areas free of tree canopy or urban canyons, the continued existence of fixed point networks is still needed for administrative and legal purposes on local and regional scales.
It is managed by Ordnance Survey. It provides access to a stable, national coordinate reference system (through downloaded GNSS data) that allows highly accurate location to be determined using suitable equipment, and is used in surveying, construction and precision agriculture industries, among other uses.
Hardware-wise, A GNSS receiver is needed to interpret satellite signals and compute the user’s location. Nowadays, it is usually a single integrated circuit (IC).. Satellite navigation software is most commonly used on mobile devices, particularly mobile phones, to provide the positioning functionality.
Vehicle navigation on a personal navigation assistant Garmin eTrex10 edition handheld. A satellite navigation device or satnav device, also known as a satellite navigation receiver or satnav receiver or simply a GPS device, is a user equipment that uses satellites of the Global Positioning System (GPS) or similar global navigation satellite systems (GNSS).
Hemisphere GNSS designs and manufactures precision global positioning system and global navigation satellite system products and technology for positioning, heading, guidance, navigation, machine control, and L-band correction service applications. [1]
Glider pilots use GNSS Flight Recorders to log GNSS data verifying their arrival at turn points in gliding competitions, and for information to aid en route decision making for cross-country soaring. Boats and ships can use GNSS to navigate all of the world's lakes, seas and oceans. Maritime GNSS units include functions useful on water, such as ...

StarFire is a wide-area differential GPS developed by John Deere's NavCom and precision farming groups. StarFire broadcasts additional "correction information" over satellite L-band frequencies around the world, allowing a StarFire-equipped receiver to produce position measurements accurate to well under one meter, with typical accuracy over a 24-hour period being under 4.5 cm. StarFire is ...
