Telit Cinterion Enhances GNSS Solutions for IoT

In a strategic move that underscores its leadership in IoT solutions, Telit Cinterion has announced an expansion of its GNSS (Global Navigation Satellite System) portfolio with the introduction of two new dual-band modules: the SE873K5-D and the SE869eK5-DRK. These innovative modules represent a significant leap forward in achieving accurate and reliable positioning for a wide range of IoT applications.

Next-Generation GNSS Technology

The newly launched SE873K5-D and SE869eK5-DRK modules are designed to cater to the growing demands of ultracompact, power-constrained devices while delivering high-precision positioning capabilities. Powered by the advanced AG3335 chipset from Airoha, a long-time partner of Telit Cinterion, these modules are tailored for both basic and mission-critical IoT applications.

The SE873K5-D module expands upon the existing SE873K5 family by introducing a dual-band variant that operates on both L1 and L5 frequencies. This functionality allows manufacturers to achieve enhanced accuracy and resilience against interference and multipath effects, characteristics critical in IoT environments where reliable positioning is paramount.

Scalable Solutions for Diverse Applications

Device manufacturers benefit significantly from the scalability offered by these new modules. They can incorporate advanced correction technologies like RTCM (Radio Technical Commission for Maritime Services), significantly improving the positioning accuracy across various connected deployments without the need for major hardware redesigns.

The SE873K5-D maintains a compact structure of 7 x 7 mm, providing versatility for applications ranging from wearables to fleet management systems. Moreover, it includes dual power supply options, allowing developers to optimize their devices for space efficiency or energy usage based on their specific needs. This adaptability, paired with multiple configurable usage modes, opens up new possibilities in various IoT verticals.

The SE869eK5-DRK module epitomizes continuous and ultraprecise positioning, featuring RTK (Real-Time Kinematic) capabilities combined with untethered dead reckoning. This combination ensures centimeter-level accuracy, which persists even in environments where GNSS signals may be obstructed, such as tunnels or densely populated urban areas. The embedded inertial measurement unit (IMU) augments the module’s capabilities, ensuring seamless performance regardless of the interference levels.

With dimensions of 16 x 12.2 mm, the SE869eK5-DRK offers a proprietary extended pinout, maintaining compatibility with existing designs while allowing OEMs (Original Equipment Manufacturers) to enhance functionalities over time without extensive product redesigns.

Future-Proofing GNSS Deployments

Eric Lagorce, the global head of GNSS, Wi-Fi, and Bluetooth® technology solutions at Telit Cinterion, highlighted the importance of these new offerings, stating, "IoT applications demand smaller form factors and higher positioning performance. With the SE873K5-D and SE869eK5-DRK, we are extending our next-generation GNSS roadmap. This expansion supports ultracompact, low-power devices and mission-critical applications that require continuous, ultraprecise positioning. It also preserves design continuity for our customers."

As companies increasingly explore IoT capabilities, Telit Cinterion’s innovations position them as a key partner in navigating the complexities of connected technology. Engineering validation testing (EVT) samples for the SE873K5-D are available now, with mass production set for Q2 2026.

For those looking to explore Telit Cinterion’s groundbreaking solutions, the company will showcase these modules at the upcoming Embedded World exhibition, taking place in Nuremberg from March 10 to 12, 2026. This is a prime opportunity for industry professionals to witness firsthand how Telit Cinterion is shaping the future of GNSS technology.
