Affordable RTK GPS Receiver


Reach is for applications when a 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.

Antennas matter

High quality antennas are the key to great RTK performance. Tallysman Wireless, an industry leading company in high accuracy antennas provided their latest advanced antennas for the project. These antennas receive Glonass G1, Beidou B1, GPS L1 and Galileo E1 signals as well as signals from corrections services.

“The Emlid Reach program is an excellent example of the potential for huge reductions in cost available of precision RTK positioning systems. Tallysman’s Accutenna™ technology is a great match for the Reach product because it too provides high precision at new price levels.  Just as one wouldn’t expect a high quality image from an expensive TV receiver with a “rabbit ear” antenna, one should not expect the levels of precision the Reach product is capable of with a low precision antenna. Tallysman’s raison d’etre is production of high quality, high precision antennas at an affordable price for systems exactly such as the Emlid Reach product.”
