A dual-band, multi-constellation positioning receiver with untethered dead reckoning (UDR) has been integrated into Telit Cinterion’s AG3335 chipset family to provide continuous positioning even when satellite signals are lost due to jamming, interference or physical obstructions.
Dubbed the SE869eK5-DR, the internet of things (IoT) solution with integrated UDR is designed for mission-critical applications in business and government.
The receiver adds an integrated six-axis sensor for UDR that allows the module to maintain a position fix even when signals are blocked or jammed. This is important for connectivity where assets are inside a building or underground, like parking garages or parking towers and long tunnels or continuous tunnels.
The module supports L1 and L5 bands so that if one band’s signal is degraded, the other band provides an alternative set of signals. It also supports differential global navigation satellite systems (DGNSS) positioning for applications that require sub-meter level accuracy.
Other features of the module include:
- 34 pins for future use
- Backward compatible with 24-pin generations
- Automatically identifies direction of movement
- Eliminates need for separate heading pin
“This innovation will benefit fleet management, as well as emerging transportation operations like shared bicycles, shared cars, and motorcycles,” said Kevin Chen, GM at the Positioning Communications Product Business Unit of Airoha Technology. “We will continue to advance key technologies in the GNSS industrial application field."
