u-blox, a global leader in positioning and wireless communication technologies, has launched the first satellite IoT-NTN cellular module with built-in GNSS, solving remote connectivity challenges.

u-blox today announced the launch of its first 3GPP-compliant terrestrial network (TN) and non-terrestrial network (NTN) combined IoT module, SARA-S528NM10.

New modules based on this technology standard are emerging as game changers in the satellite IoT market by enabling low-power, simultaneous, accurate positioning capabilities essential for use cases requiring continuous or periodic asset tracking and monitoring, while simultaneously supporting global coverage.

Other IoT use cases include aftermarket telematics, industrial monitoring and control, smart metering and utilities, and fleet management.

With cellular networks covering only 10% of the globe, there is a growing need for guaranteed global coverage, especially for IoT applications such as asset tracking in remote or maritime environments.

Satellite IoT could fill this gap, but its adoption has been partially limited by the high cost and power consumption of satellite terminals, as well as the high cost of satellite communications.

Nevertheless, the satellite IoT market is expected to grow to 2030ABI Research predicts that it will exceed $4 billion by 2020.

Current satellite connectivity solutions require proprietary hardware and software, locking the terminal into a specific satellite operator, requiring users to replace their satellite terminal if they want to move to a different satellite operator. In contrast, u-blox’s solutions are based on global 3GPP standards and can be certified for interoperability with multiple satellite operators that support those standards, maximizing customer choice.

“u-blox’s new satellite IoT-NTN cellular module is designed to maintain connectivity even in areas without cellular coverage,” said Stephan Zizala, CEO of u-blox. “Our new integrated GNSS solution consumes less than 15mW in continuous tracking mode and boasts excellent RF sensitivity to significantly reduce the time needed to obtain a position fix. Providing position data simultaneously without interrupting the cellular or satellite connection reduces the device’s uptime, which helps to minimize power consumption.”

Based on the u-blox UBX-S52 cellular/satellite chipset and GNSS M10 platform, the module is compliant with the 3GPP Rel 17 NB-NTN specification. This standards-based approach ensures connectivity over 3GPP Rel 17 compliant terrestrial cellular networks via LTE-M and NB-IoT, as well as extended connectivity over geostationary orbit (GEO) satellites via NB-IoT, in addition to reception of low-Earth orbit (LEO) satellites. The UBX-S52 cellular/satellite chipset is currently in the process of certification with global NTN service operator Skylo for their satellite network. This certification seamlessly supports both cellular and Skylo satellite connections, enabling an enhanced and more reliable experience that utilizes resources efficiently.

The SARA-S528NM10 module future-proofs and strengthens technology by supporting all three new NTN bands – n23 (US), n255 (Global L-band), and n256 (European S-band) – and is pin-compatible with other u-blox cellular-only modules in the SARA form factor, allowing engineers to easily extend the design of IoT products using existing technologies without costly redesign.
