    Syslogic introduces cm-accurate navigation with computer expansion board with u-blox

    Syslogic has introduced a GNSS expansion board for its rugged embedded computers.

    Based on u-blox GNSS technology, the board provides centimeter-level positioning, opening up new applications across industries such as autonomous field management, operation of construction machinery in remote areas, or navigation of automated guided vehicles and autonomous mobile robots.

    All-band, multi-frequency reception and HAS-ready

    Syslogic’s all-band GNSS board is powered by the u-blox X20 receiver, supporting all major GNSS constellations and frequencies, including L1, L2, L5, L6 and L-band. This enables the use of the upcoming Galileo High Accuracy Service (HAS).

    HAS supplements standard Galileo Open Service positioning with correction data transmitted directly over the E6/L6 band. The result is centimeter-level positioning via GNSS signals — without the need for traditional RTK base stations, costly reference networks, or 5G connectivity. HAS is free and globally available.

    The u-blox X20-based GNSS board also supports simultaneous multi-frequency reception. With additional frequencies compared to previous models, typical GNSS errors — such as multipath effects and signal blockage — are significantly reduced, particularly in urban environments. This is crucial for applications that demand highly precise and reliable positioning, including surveying, autonomous vehicles, agricultural machinery and industrial automation.

    The GNSS board is designed for worldwide use. The integrated u-blox receiver supports modern correction techniques such as RTK, PPP-RTK and PPP. For the first time, it has been fully optimized for PointPerfect Global, u-blox’s proprietary high-precision GNSS correction service, delivering centimeter-level positioning anywhere in the world. This is particularly useful in remote areas without cellular coverage. PointPerfect Global uses advanced PPP-AR technology (precise point positioning with ambiguity resolution), providing corrections via the Internet or L-band satellite transmission. The service achieves convergence times of less than 2 minutes and positioning accuracy within 10 centimeters.

    The new expansion board is compatible with Syslogic embedded computers, including both Nvidia Jetson-based and x86-based devices. It is available with either one or two receivers, enabling RTK and heading functions without additional hardware. Vehicles and machines can be positioned with centimeter-level accuracy.

    Several Syslogic customers are already using the GNSS functionality in pilot projects, including precision farming and construction machinery monitoring.

      TomTom and STMicroelectronics to offer geolocation tools and services

      STMicroelectronics and TomTom are offering a package of development geolocation tools in the STM32 Open Development Environment.

      The tools connect directly to TomTom Maps APIs (Application Programming Interfaces) for location, tracking and mapping data services, accelerating product development, and reducing time-to-market and development costs for developers, the companies said.

      The development package consists of an STM32 Discovery host board for 2G/3G cellular-to-cloud connectivity, a GNSS expansion board based on ST’s Teseo satellite navigation technology, and a software Function Pack that connects an internet-of-things (IoT) node via a cellular network to a range of TomTom Maps APIs.

      With this hardware and software package and a TomTom developer account, developers can quickly add location-based services to their IoT and smart city applications.

      Among these services are the translation of GPS coordinates into a street address inside a map (Reverse Geocoding), retrieval of nearby point of interests, and the production of accurate navigation directions.

      “We have combined TomTom’s industry-leading location-based and mapmaking technologies with ST’s unrivaled combination of silicon and system expertise to create a unique offering that provides easy access to TomTom’s Maps APIs to empower developers to create groundbreaking, location-aware applications faster and more efficiently,” said Anders Truelsen, managing director of TomTom’s Enterprise Business Unit.

      “Supporting our efforts to facilitate location-based product development, our collaboration with TomTom has built on each company’s strengths to assemble a tailored package of hardware and software tools that is already fully integrated with TomTom cloud services, around the popular STM32 development ecosystem,” said Alessandro Cremonesi, group vice president at STMicroelectronics. “These tools enable native STM32-based location services to accelerate application development of Geo-IoT solutions for fleet management, item tracking, and many other services that depend on fast, accurate location detection.”

      In addition to the STM32 family of Arm Cortex-M core microcontrollers, the development tools leverage ST’s market-proven multi-constellation Teseo positioning-receiver technology to perform all positioning operations including tracking, acquisition, navigation and data output.
