As IoT deployments push for more reliable positioning in smaller devices and tougher RF environments, Telit Cinterion has introduced two new dual-band L1+L5 GNSS modules. The additions extend its roadmap from ultracompact designs to RTK and dead reckoning options aimed at scalable product families.
Positioning has become a design constraint again—this time not because GNSS is new, but because many IoT applications are demanding higher reliability in places where satellite signals are fragile. Dense urban areas, tunnels, interference, multipath reflections, and aggressive power budgets all conspire to make “basic GPS” less predictable for tracking, telematics, and mobile industrial devices.
Against that backdrop, Telit Cinterion is expanding its next-generation GNSS portfolio with two dual-band modules: the SE873K5-D, positioned as an ultracompact option, and the SE869eK5-DRK, aimed at higher-end designs that need continuous positioning. Both are built on Airoha’s AG3335 chipset series, continuing what the company describes as a long-standing partnership with the chip vendor.
Two modules, two tiers of positioning requirements
The more compact of the two, the SE873K5-D, extends Telit Cinterion’s existing SE873K5 family with a dual-band L1+L5 variant. The company’s key message to device makers is design continuity: it keeps the same 7 x 7 mm footprint and is pin-to-pin compatible with the single-frequency SE873K5, enabling OEMs to scale to dual-band without reworking hardware layouts.
Functionally, the module supports multiconstellation GNSS across the L1 and L5 bands. Telit Cinterion says that, versus single-frequency approaches, dual-band improves accuracy and robustness against interference and multipath effects—attributes that are particularly relevant for wearables and fleet management devices that operate in mixed indoor/outdoor conditions. The company also states the module supports DGNSS via RTCM corrections for submeter accuracy, and that it is offered with two power supply variants to help designers optimize either for minimal size or ultralow power consumption. Configurable usage profiles, including tracking and drone modes, are also highlighted.
At the top end, Telit Cinterion introduced the SE869eK5-DRK as the next step in its higher-end GNSS line. Based on an upper tier of the AG3335 family, the SE869eK5-DRK builds on the previously announced SE869eK5-DR by adding RTK positioning alongside untethered dead reckoning (UDR). The module integrates an inertial measurement unit (IMU), intended to help maintain accurate position fixes when GNSS signals are degraded or blocked, such as in tunnels or dense urban areas.
For situations where RTK corrections are not available—or where centimeter-level precision isn’t required—Telit Cinterion says the SE869eK5-DRK also supports DGNSS for submeter accuracy. In mechanical terms, it comes in what the company calls an industry-standard 16 x 12.2 mm form factor, and introduces a proprietary extended pinout while remaining backward-compatible with existing designs.
Why the roadmap matters for OEMs and integrators
Beyond the headline of “two new modules,” the more telling element is the portfolio framing. Telit Cinterion is positioning these parts as stepping stones that let product teams move between accuracy tiers—single-frequency to dual-band, DGNSS to RTK—without a full hardware redesign. In practice, that matters for OEMs trying to build a single device platform that can be configured into multiple SKUs for different customer requirements and price points.
The press release also ties positioning performance to connectivity. Telit Cinterion says that, when combined with its cellular connectivity solutions, the modules support injection of RTCM corrections worldwide. For solution providers, that points to a more integrated approach where GNSS accuracy is not just a receiver decision, but also an architecture decision involving how correction data is delivered and managed across a deployed fleet.
“IoT applications demand smaller form factors and higher positioning performance. Customers need a GNSS portfolio that can scale with their requirements,”

On availability, Telit Cinterion states that engineering validation testing (EVT) samples of the SE873K5-D are available now, with design validation testing (DVT) samples expected soon, and mass production planned for Q2 2026. For the SE869eK5-DRK, DVT samples are available now, with mass production also planned for Q2 2026.
