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]
This procedure using three-time pairs and a fairly good initial value followed by iteration will result in one observed triple-difference result for the receiver 2 positions. Greater accuracy may be obtained by processing triple-difference results for additional sets of three independent time pairs.
[2] [3] IPS can achieve position accuracy of 2 cm, [4] which is on par with RTK enabled GNSS receivers that can achieve 2 cm accuracy outdoors. [5] IPS use different technologies, including distance measurement to nearby anchor nodes (nodes with known fixed positions, e.g. WiFi / LiFi access points , Bluetooth beacons or Ultra-Wideband beacons ...
Precise positioning is increasingly used in the fields including robotics, autonomous navigation, agriculture, construction, and mining. [2]The major weaknesses of PPP, compared with conventional consumer GNSS methods, are that it takes more processing power, it requires an outside ephemeris correction stream, and it takes some time (up to tens of minutes) to converge to full accuracy.
Lehmann Aviation Ltd (France), designs and manufactures professional civilian drones/UAVs since 2005. The company has two lines of UAVs: L-A series line of fully automatic drones designed for high precision mapping; construction/mining and precision agriculture; and L-M series line of both automatic and ground-controlled drones for long-range real-time surveillance.
Traverse networks involve placing survey stations along a line or path of travel, and then using the previously surveyed points as a base for observing the next point. Connected survey lines form the framework and the directions and lengths of the survey lines are measured with an angle measuring instrument and tape or chain. [2]

Indian Regional Navigation Satellite System (IRNSS), with an operational name of NavIC (acronym for Navigation with Indian Constellation; also, nāvik 'sailor' or 'navigator' in Indian languages), [2] is an autonomous regional satellite navigation system that provides accurate real-time positioning and timing services.
