As IoT deployments continue to drive demand for positioning reliability in smaller devices and more demanding RF environments, Telit Cinterion has launched two new dual-band L1+L5 GNSS modules. These new modules expand its product roadmap from ultra-compact designs to RTK and dead reckoning options. Therefore, this creates a scalable product portfolio.
Positioning is once again a design constraint — this time not because GNSS technology itself is new. Instead, many IoT applications require higher reliability in environments where satellite signals are weak. Factors such as dense urban areas, tunnels, interference, multipath reflections, and tight power budgets all reduce the positioning reliability of “basic GPS”. This is especially problematic in areas such as tracking, telematics, and mobile industrial equipment. Furthermore, developments in IoT continue to influence how solutions address these constraints.
Against this backdrop, Telit Cinterion is expanding its next-generation GNSS portfolio with two dual-band modules: the SE873K5-D, positioned as an ultra-compact product, and the SE869eK5-DRK, targeting high-end designs requiring continuous positioning. Both products are based on Airoha’s AG3335 chipset series. This continues the company’s long-standing partnership with this chip supplier and its commitment to evolving IoT technology.
Two modules, catering to two positioning needs
The smaller SE873K5-D is an extension of Telit Cinterion’s existing SE873K5 series, adding an L1+L5 dual-band version. A key message the company conveys to equipment manufacturers is design continuity. It maintains the same 7 x 7 mm package size and is pin-compatible with the single-band SE873K5. This allows OEMs to scale to dual-band without redesigning hardware layouts.
Functionally, the module supports multi-constellation GNSS in both L1 and L5 bands. Telit Cinterion states that compared to a single-band solution, the dual-band approach improves positioning accuracy and interference immunity. Moreover, it enhances resistance to multipath effects — characteristics particularly important for wearable devices and fleet management equipment. These advantages are most significant for equipment operating in mixed indoor and outdoor environments. The company also stated that the module supports sub-meter accuracy DGNSS via RTCM correction and offers two power supply versions. This helps designers optimize size or achieve ultra-low power consumption according to their needs. Furthermore, the module highlights configurable usage modes, including tracking mode and drone mode. For designers working on IoT projects, these features are especially valuable.
On the high-end front, Telit Cinterion introduced the SE869eK5-DRK, the latest addition to its high-end GNSS product line. Based on the high-end AG3335 series, the SE869eK5-DRK adds RTK positioning and untethered dead reckoning (UDR) capabilities to the previously released SE869eK5-DR. The module integrates an inertial measurement unit (IMU) designed to help maintain accurate positioning when GNSS signals are weakened or blocked, such as in tunnels or densely populated urban areas. As a result, accurate IoT tracking in complex environments is now more achievable.
For applications where RTK calibration is not feasible or centimeter-level accuracy is not required, Telit Cinterion states that the SE869eK5-DRK also supports DGNSS, achieving sub-meter accuracy. Mechanically, it adopts what the company calls an industry-standard 16 x 12.2 mm form factor and introduces a proprietary extended pin arrangement. At the same time, it maintains backward compatibility with existing designs.
Importance of the Product Roadmap for OEMs and Integrators
Beyond the headline “Two New Modules,” the framework of the product portfolio is even more inspiring. Telit Cinterion positions these components as transitional modules, enabling product teams to switch between different accuracy levels — from single-band to dual-band, from DGNSS to RTK — without requiring a complete hardware redesign. In fact, this is crucial for OEMs looking to build a single device platform. Such a platform can be configurable as multiple SKUs to meet different customer needs and price points.
The press release also links performance to connectivity. Telit Cinterion states that these modules, when used in conjunction with the company’s cellular connectivity solutions, support the global injection of RTCM correction data. For solution providers, this means a more integrated approach where GNSS accuracy depends not only on the receiver but also on architectural decisions. These decisions include how correction data is transmitted and managed across deployed base station networks.
“IoT applications require smaller size and higher positioning performance. Customers need a GNSS portfolio that can scale with their needs,” said Eric Lagorce, Global Head of GNSS, Wi-Fi, and Bluetooth® Technology Solutions at Telit Cinterion. Clearly, advancements in IoT are driving new requirements for GNSS modules.
Regarding product availability, Telit Cinterion states that Engineering Verification Test (EVT) samples of the SE873K5-D are now available, with Design Verification Test (DVT) samples expected soon, and mass production planned for Q2 2026. DVT samples of the SE869eK5-DRK are also available, with mass production planned for Q2 2026.
