Centimeter-Accurate Solution

RTK Rover is an low-power, easy-to-use dev kit that lets you add centimeter-accurate positioning to anything you design. With it, you can build a stand-alone RTK receiver such as those used by professional surveyors in the field. Our Mini PCIe module includes a dual-band, all-constellation, LC29H GNSS module from Quectel, and our on-board inertial measurement unit (IMU) tracks position through dead reckoning when GNSS is lost.

RTK Rover has 1 centimeter accuracy and top notch performance that is comparable to $20 K Geodetic grade survey equipment, but at a 99% discount!

USB Rover Kit

The small, magnetic-mount, dual-band antennas offer excellent signal reception on your car, robot, drone, or backpack. Connect to the Internet-based GEODNET network to receive a GNSS correction stream that requires only a few seconds to improve your Fixed RTK accuracy to within a few centimeters. The EmbedCM RTK Evaluation Kit supports standard NMEA output messages and comes with an open-source decoder and logger written in Node.js.

We also provide a second Raspberry Pi HAT that provides a USB Type-C interface, an event interface, an odometer connection, and plug-and-play connectivity to a Raspberry Pi 4B. Our handsome metal enclosure allows you to build your own professional-quality, high-accuracy GNSS receiver with support for Ethernet, Wi-Fi, and USB connectivity – a product that would normally cost you thousands of dollars!

Ethernet Rover Kit with Raspberry Pi 4B

USB-C or Ethernet, the choice is yours to select a USB or a more powerful Ethernet Pi4B-based device to take your project to the next level. Both versions provide built-in trial account access with centimeter-accurate precision to the world’s largest decentralized GNSS reference network, GEODNET.

Introduced at the Institute of Navigation 2021 GNSS Conference, the Global Earth Observation Decentralized Network (GEODNET) received a "best presentation award", and has rapidly grown since our official launch in early 2022. With over 3000 reference stations online on every major continent, the GEODNET is the world’s largest decentralized, real-time geospatial reference network. Check out the live reference station map: https://console.geodnet.com/map RTK Rover is compatible with other network options, however, the cost may reach 10x cost of GEODNET (free trial only available for GEODNET).

Support & Documentation

You can find schematics, source code, drivers, and docs in our GitHub repository.

We plan to add more software capabilities, especially for the Raspberry Pi version. This is ongoing and more features will be shared as they are tested. In addition, we plan to shoot more demo videos with the Rover in many use cases, including vehicle testing, package tracking, and in various robots. These tests will be executed and shared with the community. We welcome content and ideas from users.
