GNSS module with dead reckoning

Quectel’s L26-DR is a concurrent multi-GNSS (global navigation satellite system) receiver module with dead reckoning capability, provided by a 6-axis MEMS sensor MEMs and a powerful GNSS core. The module provides high sensitivity, fast GNSS signal acquisition and tracking with low system integration effort.
The device can acquire and track any mix of GPS, GLONASS, BeiDou, Galileo and QZSS signals. Multi-constellation support allows accurate navigation in harsh environments, such as urban canyons. The dead reckoning feature enables it to deliver high-performance positioning even when a GNSS signal is absent or compromised, and the built-in LNA (low-noise amplifier) provides better performance under weak signal areas.
Compared with using GPS only, enabling multiple GNSS systems generally increases the number of visible satellites, reduces the time to first fix, and increases positioning accuracy, especially when driving in rough urban environments.
Its performance makes the L26-DR ideal for automotive, industrial and consumer applications. Very low power consumption makes it easier to be applied to power sensitive devices, especially portable applications.
