U-Blox multi-band GNSS module delivers centimetre-level accuracy

Swiss company U-Blox has announced a multi-band GNSS module with integrated multi-band real-time kinematics (RTK) technology for machine control, ground robotic vehicles and high-precision unmanned aerial vehicle (UAV) applications.
 
The ZED-F9P measures 22 by 17 by 2.4mm and uses technology from the recently announced U-Blox F9 platform to deliver robust high-precision positioning performance in seconds.
 
The module is said to be the first mass-market multi-band receiver to use GNSS signals concurrently from all four GNSS constellations (GPS, Glonass, Galileo and Beidou). Combining GNSS signals from multiple frequency bands (L1, L2 and L5) and RTK technology lets the module achieve centimetre-level accuracy in seconds. And receiving more satellite signals at any given time increases the availability of centimetre-level accuracy even in difficult environments such as in cities.
 
With its high update rate, the module is suitable for highly dynamic applications such as UAVs. Featuring on-chip integration of multi-band RTK algorithms, it requires no additional hardware or third-party RTK libraries. Ready to use on delivery and easy to integrate, it can help product developers quickly bring their ideas to the market.
 
The module is geared to clearing the three main hurdles that have kept centimetre-level positioning accuracy from breaking into mass-market applications: cost, size and power consumption. Claimed to be smaller and more energy efficient than existing products, and as a cost efficient alternative, the module could enable new high precision positioning applications for the mass market.
 
“The new ZED-F9P GNSS receiver builds on the success of our NEO-M8P high precision GNSS module, but takes performance to another level by leveraging all the available GNSS signals,” said Mårten Ström, senior principal product manager at U-Blox. “By making robust and affordable high precision positioning technology more accessible, we hope to fuel innovation and enable a new generation of high precision GNSS navigation applications.”
 
Engineering samples will be available from the end of July 2018.
 
With headquarters in Thalwil, Switzerland, U-Blox is globally present with offices in Europe, Asia and the USA.
 
Tri Cascade, a subsidiary of SkyFidelity and an IoT technology company, has announced a collaboration with U-Blox. Using the portfolio of U-Blox 4G products, including NB-IoT and LTE Cat M1 modules, Tri Cascade will deliver energy efficient smart neighbourhood products to global customers.
