About the GPS RTK module, Although GPS simplifies positioning for applications like surveying, the system has high inaccuracies. And the same applies to other GNSS constellations like GLONASS and Galileo. GPS positioning can be off by up to five meters, a significant variation when measuring land boundaries. <\/p>\n\n\n\n
However, an RTK module sharpens this accuracy to less than 10cm, sometimes even a centimeter. We will define a GPS RTK module and explain its functioning mechanism. Let’s get right into it!<\/p>\n\n\n
RTK is short for real-time kinematics. RTK positioning applies surveying techniques to correct errors in GNSS constellation systems like GPS. So a GPS<\/a> RTK board takes in the regular GPS signal plus an additional correction stream to enhance positioning accuracy.<\/p>\n\n\n RTK uses measurements of the signal carrier wave’s phase plus the signal content’s information to get the position data. On top of that, it relies on data from a single reference station (or a virtual interpolated station) to supply a real-time RTCM<\/a> correction stream to provide centimeter-level accuracy to the base station.<\/p>\n\n\n\nHow RTK Works<\/h2>\n\n\n
