California-based Hyfix.AI has built a GNSS Geodnet base station with centimetre-level accuracy using Chinese company Quectel’s LC29H dual-band GNSS module.

Geodnet is a decentralised network of high-precision multi-band GNSS base stations for AIoT, geo-scientific and metaverse applications.

The partnership should reduce the cost and increase the availability of centimetre-accurate technology for global AIoT applications.

The mobile-centimetre dual-band GNSS station is for real-time kinematic (RTK) precise-positioning applications in autonomy, agriculture, construction, survey, drones and geo-science.

Introduced at the Institute of Navigation 2021 GNSS Conference, the Global Earth Observation Decentralised Network, Geodnet, received the best presentation award and has rapidly grown since its official launch in early 2022. The mobile-centimetre station automatically uploads real-time satellite data to Geodnet via a wifi-based internet connection.

Mobile-centimetre base stations are self-hosted and receive Geodnet token rewards while powering both commercial AIoT as well as citizen science climate change applications.

The Quectel LC29H module is a surface-mount low-power 135-channel dual-band receiver. It can host both RTK and dead reckoning algorithms such as the Hyfix.AI embedded centimetre stack. Using GNSS correction from a service such as Geodnet or other networks, the modules can achieve position accuracy of 10cm in various real-world conditions.

The mobile-centimetre base station which embeds the LC29H as well as the ATECC608B crypto-authentication engine is simple to install and connect to the internet. The included installation kit provides a survey-grade triple-band GNSS antenna, primary antenna cable and roof-top installation hardware.

“Quectel is excited to continue its partnership with Hyfix.AI to deliver precise GNSS positioning accuracy of 10cm in the real world using our dual-band LC29 family of GNSS modules,” said Mark Murray, vice president at Quectel.

Mike Horton, CEO of Hyfix.AI, added: “Hyfix.AI is pleased to continue support of Quectel’s dual-band LC29 GNSS modules and introduce a new turn-key Geodnet base station for global precise positioning.”

Quectel has a growing global team of more than 4000 professionals working on cellular, GNSS, wifi and Bluetooth modules, antennas and IoT connectivity.
