u-blox Centimeter-level precise positioning

Centimeter‑level accuracy by combining RTK technology and u‑blox GNSS expertise

High precision positioning can be achieved by combining Global Navigation Satellite Systems (GNSS), such as GPS, GLONASS, Galileo and BeiDou, with Real Time Kinematics (RTK) technology. RTK is a technique that uses the receiver’s measurements from the phase of the signal’s carrier wave. These measurements combined with corrections from a local “base” station or virtual base station, allow the receiver to solve carrier ambiguities and provide cm‑level accurate position information to the end‑user, a moving device, typically is referred to as the “rover”.

The demand for lower priced high precision technology is growing rapidly, as evident in the areas of precision agriculture, UAVs, and robotic lawnmowers. However, due to size, power, and cost restrictions, existing high precision solutions have been unable to meet the demands of these markets. u‑blox has developed the recently launched NEO‑M8P to meet these growing demands.

Together with u‑blox’s GNSS expertise and the implementation of RTK technology, the NEO‑M8P provides centimeter‑level accuracy for the mass market.
