High accuracy L1 RTK GNSS
RTKLIB is an amazingly powerful open-source software written by Tomoji Tokasu for RTK and postprocessing. Algorithms used to determine accurate position are computational intensive and RTKLIB was mostly used on PCs and laptops. We have created a tiny, yet very powerful module that runs RTKLIB and locates your position with centimeter precision.
Knowing precise position is not always enough, Reach packs an inertial measurement unit with 3-axis gyroscope, 3-axis accelerometer and 3-axis magnetometer. This opens new possibilities for orientation estimation and for fusion with GPS data. In the future we will be able to improve positioning accuracy using the IMU.
Powered by Intel Edison Reach is truly an internet of things device. Wi-fi and Bluetooth 4.0 connectivity is already built-in, allowing for easy communication to your smartphone, tablet or cloud. And when there is no Wi-fi hotspot nearby USB OTG will power LTE modem.
Intel Edison inside
For heavy number crunching we needed something powerful, yet very compact. Intel Edison came just right for Reach – it has everything needed in a very small footprint. With dual core, dual threaded Intel® Atom™ CPU and 1Gb of RAM it is incredibly fast and extensive connectivity opens many options for interfacing to target device.
Main function of Reach is to compute precise coordinates. To do so it uses technology called RTK – Real-time kinematics. Two connected receivers within 10km radius are used and static device streams corrections to the moving one. You can simply connect one device to your home router and another one to a smartphone with web access.
One of the challenges with high precision GPS is pricing. We use off-the-shelf components and open-source software to reduce pricing to a minimum. If you own one Reach, you can send corrections to unlimited number of other devices in 10km area. RTKLIB is capable of RTCM streaming and thus Reach is compatible with other RTK systems.
