Telit Cinterion has announced a dual-band, multi-constellation positioning receiver with untethered dead reckoning (UDR).

Built on the Airoha AG3335 chipset family, the SE869eK5-DR features UDR that ensures reliable, continuous positioning even when satellite signals are lost due to jamming, interference or physical obstructions.

With its power-efficient design, the module (www.telit.com/devices/se869eK5-DR) suits mission-critical applications in business and government that demand reliable location information and long battery life.

Building on the Telit Cinterion SL869 series (www.telit.com/devices/sl869l-v2/), the SE869eK5-DR adds an integrated six-axis sensor for UDR. This combination allows the module to maintain a position fix even when signals are blocked or jammed, making it suitable for tracking high-value assets deep inside buildings or in underground parking garages.

The module also supports L1 and L5 bands, which increases resiliency through frequency redundancy. For example, if one band’s signals are degraded by physical obstructions, the other band provides an alternative set of signals. The module also supports differential GNSS positioning for applications that require sub-metre level accuracy.

Several features streamline product development. For instance, its UDR technology is simple to integrate because it doesn’t require any external application information, which shortens the design phase. It also automatically identifies the direction of movement (forward or reverse), eliminating the need for a separate heading pin.

While it introduces an additional 34 pins for future use, it remains backwards compatible with previous 24-pin generations. This allows device OEMs to upgrade existing designs easily on this community form factor, which measures 12.2 by 16mm, and expands product capabilities over time.

Telit Cinterion (www.telit.com) is showing the product on its stand (E314) at this week’s SIDO (www.sido-lyon.com) event in Lyon, France.

“Airoha Technology has been a strategic partner of Telit Cinterion for GNSS receivers for a decade,” said Kevin Chen, general manager at Taiwanese firm Airoha Technology (www.airoha.com). “Before SIDO Lyon 2025, they unveiled the first SE869eK5-DR module equipped with UDR technology, which can assist in scenarios where GNSS signals are obstructed, weak or insufficient, such as long tunnels, continuous tunnels, underground parking lots and parking towers. This innovation will benefit fleet management, as well as emerging transportation operations like shared bicycles, shared cars and motorcycles. We will continue to advance key technologies in the GNSS industrial application field.”

Eric Lagorce from Telit Cinterion, added: “The Telit Cinterion SE869eK5-DR module balances reliability, accuracy, efficiency and flexibility. With the help of our long-time partner Airoha, we fill a void in the GNSS module marketplace to provide fleet management, automotive telematics systems and asset trackers with seamless, dependable access to positioning information, even underground or amid jamming.”

Engineering validation testing samples are available now, with design validation testing samples scheduled for November.
