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!
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!
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).

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.
Our RTK Rover devices will be manufactured by HYFIX’s longterm trusted manufacturing partner. The core GNSS module used is based on the Quectel LC29H module. We have already fabricated the first batch of units, and final testing and firmware loading will occur once we’ve received the units from the factory. All boards will be 100% tested before shipped to backers.
Our same manufacturing partner is also creating the custom metal housing. Both faceplates of the metal housing will be plastic to prevent overheating. We already received prototypes and validated a proper fit and thermal properties, which fully meet our requirements.
HYFIX branded packaging has been designed and will offer protective layers for shipment.
Teaming up with Crowd Supply allows us to utilize the global logistics capabilities of Mouser Electronics, Crowd Supply’s fulfillment partner. Once HYFIX EVK Rover kits leave the factory, Mouser will make sure it gets shipped directly to your doorstep. You can learn more about Crowd Supply’s fulfillment service under Ordering, Paying, and Shipping in their guide.
The most significant risk lies in the supply chain, primarily due to potential delays caused by shortages of components. Despite the fact that such problems are sometimes unavoidable, our extensive experience in producing GNSS devices has enabled us to decrease the probability of encountering such issues and minimize their impact. Nonetheless, we pledge to maintain transparency and candor regarding our manufacturing progress.
Our additional challenge is that the Raspberry Pi Compute Module 4 has been especially hard to source in bulk, though many of the CM4 variants are available in low quantities at various vendors. We have sourced stock from previous projects and will be able to fulfill a good amount of Raspberry Pi Rover kits (ethernet). However, if we do sell out, those who have a Raspberry Pi Module may find it quicker to purchase the USB Rover and install the Raspberry Pi Module themselves. Our products will have listed shipping timelines to reflect all estimated ship dates.
