As standard consumer grade GPS is simply not accurate enough, so the solution involves implementing your very own RTK-GPS hardware and an accompanying base station, introducing centimeter-level ...

They differ in precision and price. "One of them is a 4-inch accuracy system, known as a differential corrected GPS," he said. "The other is a RTK, real time kinematic, system, which has an accuracy ...

Generally, UAVs use a differential GPS (DGPS ... Up till now, navigation of SP.X-6 relied solely on the GPS signal. Using RTK technique for the landing process will enhance navigation accuracy. The ...

Surveyors and geodesists developed a relative or differential ... time kinematic or RTK positioning capability widely used today, as well as attitude determination. It was in March 2001 that we ...

The use of real-time differential correction is the most convenient and productive method for operating GPS\GNSS surveys ... and of phase for positioning with a precision of a few centimetres (RTK).
