RTK stands for Real-Time Kinematic, a technology that increases the accuracy of GNSS signals using fixed-positioned base stations that send GNSS corrections to an RTK receiver. With these corrections, the GNSS receivers can achieve within 1-2 centimeter accuracy.
Using a GNSS receiver without RTK for surveying results in significantly poorer accuracy, typically ranging between 2 and 10 meters. However, RTK surveying can achieve centimeter accuracy, making it the most reliable technology for survey accuracy.
But, survey accuracy with RTK can still vary between different RTK service providers. So, if you want the highest level of survey accuracy, use Point One. Point One offers unparalleled GNSS accuracy. Surveyors can access cm-accurate positioning on your hardware–even in challenging environments such as urban canyons and occluded sky-views.
