Although these parameters limit the usefulness of the RTK technique for general navigation, the technique is perfectly suited to roles like surveying. In this case, the base station is located at a known surveyed location, often a benchmark, and the mobile units can then produce a highly accurate map by taking fixes relative to that point.
This requires specially equipped receivers. This method has many applications in the field of surveying. We now describe a method that could potentially be used to estimate the position of receiver 2 given the position of receiver 1 using triple differencing followed by numerical root finding and a mathematical technique called least squares. A ...
RTK may refer to: Science and technology. Real-time kinematic positioning, a technique for precision satellite navigation; Receptor tyrosine kinase, ...
Surveying or land surveying is the technique, profession, art, ... that can be over 20 km long. RTK surveying uses one static antenna and one roving antenna. The ...
PPP is a combination of several relatively sophisticated GNSS position refinement techniques that can be used with near-consumer-grade hardware to yield near-survey-grade results. PPP uses a single GNSS receiver, unlike standard RTK methods, which use a temporarily fixed base receiver in the field as well as a relatively nearby mobile receiver.
It is the most accurate technique currently available to determine the geocentric position of an Earth satellite, allowing for the precise calibration of radar altimeters and separation of long-term instrumentation drift from secular changes in ocean surface topography. Satellite laser ranging contributes to the definition of the international ...
The vertices of these triangles are created from field recorded spot elevations through a variety of means including surveying through conventional techniques, Global Positioning System Real-Time Kinematic (GPS RTK), photogrammetry, or some other means.
Wireless networking – A technique of mapping and uploading the exact or accurate location of a wireless network is called wardriving. It uses signal-strength data from the wireless adapter and GPS to identify the location. Kismet for Linux is a widely used wardriving program. Wreck diving – A popular variant of scuba diving is known as ...
