A geodetic control network is a network, often of triangles, that are measured precisely by techniques of control surveying, such as terrestrial surveying or satellite geodesy. It is also known as a geodetic network, reference network, control point network, or simply control network.
Archaeology — As archaeologists excavate a site, they generally make a three-dimensional map of the site, detailing where each artifact is found. [5] Surveying — Survey-Grade GNSS receivers can be used to position survey markers, buildings, and road construction. [6] These units use the signal from both the L1 and L2 GPS frequencies.
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.
Its products and technology are used in agricultural, marine, surveying, GIS mapping, and machine control markets. [ 2 ] Founded in 2013, it was created after Beijing UniStrong Science & Technology acquired Hemisphere GPS, which was subsequently renamed AgJunction. [ 3 ]
A surveyor uses a GNSS receiver with an RTK solution to accurately locate a parking stripe for a topographic survey. Real-time kinematic positioning (RTK) is the application of surveying to correct for common errors in current satellite navigation (GNSS) systems. [1]
A standard geodetic monitoring instrument in the Freeport open pit mine, Indonesia GNSS reference station antenna for structural monitoring of the Jiangying Bridge. Measuring devices (or sensors) can be sorted in two main groups: geodetic and geotechnical sensors. Both measuring devices can be seamlessly combined in modern deformation monitoring.
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 ...
