Telit Cinterion demonstrated integrated cellular and GNSS high-accuracy positioning for connected IoT applications at this week’s Things Conference in Amsterdam.

The demonstration ran on Telit Cinterion cellular and GNSS hardware. A Next SIM card provided network access.

The system used the Telit Cinterion CMB100 development kit equipped with a CMB100 LTE Cat 1 bis module. Through AT commands issued in the kit’s onboard STM microcontroller environment, the module established a network connection and downloaded Skylark Nx RTK MSM5 GNSS correction data from Swift Navigation via NTRIP (networked transport of RTCM via IP).

The correction data were then injected into a Mikroe GNSS 19 Click board equipped with a Telit Cinterion SE868K5-RTK GNSS receiver. During testing, the receiver achieved positioning precision within 1-2cm on average. The same approach, using the SE868K5-D module variant and the Skylark DX MSM1 DGNSS correction data via NTRIP, achieved an average positioning precision of better than 50cm.

A unified graphical interface allowed users to issue commands to the microcontroller, which coordinated cellular connectivity and GNSS functions. A dedicated GNSS monitoring interface displayed receiver data in real time for debugging and analysis, giving developers visibility into the complete positioning workflow.

Potential applications for connected high-accuracy positioning include smart infrastructure, micromobility, logistics and asset tracking, construction and heavy equipment, robotics and autonomous systems, industrial monitoring and automation.

“High-precision positioning traditionally requires developers to integrate and manage several separate technologies, services and interfaces,” said Eric Lagorce from Telit Cinterion (www.telit.com). “Our demonstration at the Things Conference shows how Telit Cinterion brings cellular connectivity, GNSS and IoT services together in a cohesive ecosystem. This approach can simplify development and help customers bring precise location applications to market faster.”
