The Emlid Reach RX Lightweight RTK GNSS Receiver is designed specifically for work with NTRIP corrections. RTK is a technique used to improve the accuracy of a standalone GNSS receiver. Traditional GNSS receivers, like the one in a smartphone, could only determine the position with 2–4 meters (7–13 feet) accuracy. RTK can give you centimeter accuracy.

GNSS receivers measure how long it takes for a signal to travel from a satellite to the receiver. Transmitted signals travel through the ionosphere and atmosphere and are slowed down and perturbed on the way. For example, travel time on a cloudy day and in clear sky conditions would be different. That is why it is difficult for a standalone receiver to precisely determine its position. RTK is a technology that solves this issue.

High real-time precision

Two receivers are used in RTK. One of them is stationary, another moves freely. They are called base stations and rovers.

The base's mission is to stay in one place and send corrections to a moving receiver. Rover uses that data to achieve a centimeter precise position. Any number of rovers can connect to one base if their input settings match the base's output.
