Key Takeaways

  • Telit Cinterion introduced two new dual band GNSS modules designed for both ultra compact devices and high precision industrial systems
  • The additions expand the company's GNSS roadmap with scalable L1+L5, RTK, UDR, and DGNSS capabilities
  • Both modules are built on Airoha's AG3335 chipset series and maintain backward compatible hardware designs

Telit Cinterion has taken another step into the rapidly evolving positioning technology market with two new GNSS modules intended for very different ends of the IoT spectrum. It is a market moving fast, especially as location accuracy is becoming a requirement rather than a luxury in connected devices. The company introduced the SE873K5-D and SE869eK5-DRK, both based on Airoha's AG3335 series, as part of its effort to close the gap between tiny, low power devices and the ultra precise systems inside mission critical equipment.

The narrower module of the two, the SE873K5-D, is aimed at product designers who want dual band L1+L5 performance without changing their existing hardware footprint. At 7 x 7 millimeters, it keeps the dimensions and pinout of the earlier single frequency SE873K5 variant. That might sound like a small detail, but it matters when a wearable or tracker has been designed around a tightly packed PCB. The ability to retrofit better accuracy without reworking the board can shave months off the development cycle.

Support for multiple constellations in both L1 and L5 bands gives the module more resilience to multipath interference compared to single band designs. And with DGNSS via RTCM corrections, sub-meter accuracy becomes realistic for use cases such as fleet monitoring, personal fitness devices, or small drones. It comes in two power supply variants so developers can choose either minimal physical size or the lowest possible energy profile. The configurable behavior modes are an interesting addition, designed to simplify integration across different industry verticals.

A different story emerges with the SE869eK5-DRK. Instead of optimizing for space, this module layers advanced correction technologies on top of an industry standard 16 x 12.2 millimeter footprint. Telit Cinterion added RTK support along with untethered dead reckoning, essentially merging centimeter-level accuracy with uninterrupted navigation. Since the module integrates an IMU, it can sustain a reliable position estimate in tunnels or dense urban zones when satellite signals falter. Many developers across automotive, industrial robotics, or heavy equipment know this pain point well. Losing GNSS lock at the wrong moment can break an entire operational workflow.

The module also supports DGNSS when RTK is too expensive or unnecessary for a particular deployment. A proprietary extended pinout provides new expansion options while keeping backwards compatibility. This combination of old and new is becoming increasingly common as IoT manufacturers fight to preserve design investments in long lived hardware deployments.

Both modules can pair with Telit Cinterion cellular solutions to distribute RTCM corrections globally. It is an ecosystem play that leans into the company's broader strategy to deliver end to end IoT solutions rather than isolated components. Many GNSS vendors are pursuing similar architectures, but Telit Cinterion appears intent on making scalability one of its core value propositions.

The announcement also reflects the maturing collaboration between Telit Cinterion and Airoha, whose GNSS chipsets power a growing number of modern positioning products. Airoha has been pushing deeper into dual band and high accuracy GNSS platforms in recent years, and this partnership aligns with that trajectory. The trend is driven by rising demand for precision positioning in asset intelligence, logistics optimization, and semi autonomous systems, with industry reports showing a consistent push toward L1+L5 adoption across commercial IoT.

The timing of the modules suggests Telit Cinterion is preparing for a broader market swing toward RTK capable devices beyond automotive applications. Engineering validation samples for the SE873K5-D are available, with full production expected in the second quarter of 2026. The SE869eK5-DRK is currently in the design validation testing stage and is also set for mass production in the same quarter. The parallel ramp for both products hints at coordinated deployment strategies, targeting OEMs that evaluate multiple tiers of accuracy and resilience within the same product families.

As IoT developers increasingly adopt dual band GNSS, broader market expansion will depend on component cost curves continuing to drop and whether feature rich modules like these can remain power efficient. For now, Telit Cinterion is positioning accuracy, reliability, and design continuity as the main drivers for hardware teams planning their next generation devices.
