I am using two of these ubkox zed-f9p rtk gps modules for surveying. I have a accuracy of 14mm. Sparkfun has an excellent blog on how to set up a base station and a rover to achieve cm accuracy.

RTK GPS tracks the carrier of the L1 band, which is in the order of 1.5GHz or so. This is a 1000 times faster than the L1 code, which is normally used, so tracking the phase yields in resolution ...

First, in addition to measuring the code phase, an RTK GPS receiver measures the phase of the carrier wave that the code is modulated upon. The carrier has a wavelength of about 19 centimeters. This ...

Many federal, state and local government agencies have setup RTK bases to increase RTK efficiency for their employees. Many of them make the RTK base data available to the public for free or for a ...

Geodnet CEO Mike Horton tells TheStreet how a token-incentivized GPS network is delivering centimeter-level accuracy across farms, highways, and beyond.

The Piksi is a Real-Time Kinematic (RTK) GPS receiver, best explained in reverse. The receiver part means it gets signals from satellites in Earth’s orbit.

Hex and ProfiCNC are proud to introduce the Here 3 Precision GNSS solution into the CubePilot product line-up. The Here3 Brings the world of RTK to everyone. Here 3 is our Base model GPS, it joins the ...

In the realm of GPS technology, precision is paramount. The TinkerRTK , an open-source GPS modular system, is a game-changer in this field, offering centimeter-level RTK GPS precision.

FARGO, N.D. -- In what could be an increasingly important technological advance for the region's farmers, a free RTK base station network soon will expand to cover all of northwest Minnesota.

Yuneec International’s commercial hexacopter, the H520, will now optionally be available with an RTK (real-time kinematic) system from the Swiss company Fixposition.. Under difficult GPS conditions, ...
