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. Even though the L2 code data are encrypted, the signal's carrier wave enables correction of some ionospheric errors.
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]
GPS surveying differs from other GPS uses in the equipment and methods used. Static GPS uses two receivers placed in position for a considerable length of time. The long span of time lets the receiver compare measurements as the satellites orbit. The changes as the satellites orbit also provide the measurement network with well conditioned ...
Geopositioning can be referred to both global positioning and outdoor positioning, using for example GPS, and to indoor positioning, for all the situations where satellite GPS is not a viable option and the localization process has to happen indoors. For indoor positioning, tracking and localization there are many technologies that can be used ...

In geodesy, GNSS is used as an economical tool for surveying and time transfer. [4] It is also used for monitoring Earth's rotation, polar motion, and crustal dynamics. [4] The presence of the GPS signal in space also makes it suitable for orbit determination and satellite-to-satellite tracking. Examples: GPS, GLONASS, Galileo
Geomatics includes the tools and techniques used in land surveying, remote sensing, cartography, geographic information systems (GIS), global navigation satellite systems (GPS, GLONASS, Galileo, BeiDou), photogrammetry, geophysics, geography, and related forms of earth mapping.
This makes it difficult to locate them using a handheld GPS unit. Most marks have clear descriptions for how to reach them, but some lack complete descriptions. Additionally, changes in the surrounding buildings, roads, or terrain over decades may make the descriptions obsolete, as some marks have been removed due to construction or buried over ...
