u-blox Launches SARA-S528NM10: A Breakthrough in Satellite IoT Technology

u-blox, a global leader in positioning and wireless communication technologies, has introduced the SARA-S528NM10, its first IoT module supporting both terrestrial and non-terrestrial networks (NTN). This new module, based on the 3GPP Release 17 specification, combines cellular and satellite connectivity to provide global coverage, low-power consumption, and precise, concurrent positioning. This innovation is poised to transform satellite IoT markets, addressing key needs such as asset tracking, industrial monitoring, fleet management, and smart metering, especially in remote and maritime environments.

Meeting the Growing Demand for Global IoT Connectivity

While cellular networks cover only about 10% of the Earth, the need for guaranteed global connectivity is rising, particularly for IoT applications in areas with limited or no cellular coverage. Satellite IoT has emerged as a solution to bridge this gap, although high costs related to satellite terminals, airtime, and power consumption have limited its broader adoption. However, according to ABI Research, the satellite IoT market is projected to exceed USD 4 billion by 2030, signaling a strong growth trajectory.

The SARA-S528NM10 from u-blox addresses these challenges with its standards-based approach. Unlike traditional satellite IoT solutions that require proprietary hardware and software—locking users to specific satellite providers—this module is 3GPP-compliant, allowing interoperability with multiple satellite operators. This flexibility gives customers greater freedom and reduces the need to replace hardware when switching satellite services.

Low Power, High Performance for Extended Global Coverage

Designed to maintain connectivity in areas without terrestrial cellular networks, the SARA-S528NM10 integrates u-blox’s GNSS technology, consuming less than 15mW of power in continuous tracking mode. Its high RF sensitivity ensures quicker position fixes, reducing active time and thus conserving power. This is particularly useful for applications requiring continuous or periodic tracking, where power efficiency is critical.

The module is powered by the UBX-S52 cellular/satellite chipset, which supports both LTE-M and NB-IoT networks on terrestrial systems and NB-IoT on geostationary satellites. The chipset is being certified by Skylo, a global NTN service provider, ensuring seamless integration between cellular and satellite networks. This certification will enhance reliability and optimize resource utilization, providing a more efficient IoT experience.

Future-Proofing with 3GPP Compliance and Global Band Support

The SARA-S528NM10 supports the three latest NTN frequency bands—n23 (U.S.), n255 (global L-band), and n256 (S-band Europe)—positioning it as a future-proof solution in the satellite IoT space. It is also pin-compatible with other u-blox SARA form factor modules, allowing for easy upgrades without extensive redesigns, which reduces costs and development time for IoT product manufacturers.

With this standards-based and scalable solution, u-blox is addressing key challenges in the satellite IoT market, delivering a versatile and powerful module that will help drive adoption across industries.
