Reach: first affordable RTK GPS receiver
Reach is for applications when your standard GPS with several meters accuracy just won’t cut it. It relies on RTK (real-time kinematics) technology to deliver centimeter level accuracy.
RTK was here for a long time, used mostly by surveyors and unaffordable to hobbyists and makers. If you needed centimeter precise positioning you had to spend thousands of dollars on an RTK system. With Reach we want to change that.
Reach runs open-source RTK processing software called RTKLIB written by Tomoji Takasu. Previously a computer was required to run RTKLIB, but now all RTKLIB features are available directly on Reach.
