Quectel Launches Dead Reckoning GNSS Module L26-DR

Quectel Wireless Solutions, a supplier of cellular and GNSS positioning modules, recently announced the launch of a compact dead reckoning GNSS module L26-DR at the electronica 2018 in Germany.

As the latest addition to Quectel’s comprehensive GNSS portfolio, L26-DR is a concurrent multi-GNSS receiver module embedded with dead reckoning (DR) solution, designed to greatly improve the positioning accuracy and speed while simplifying customer designs. The DR capability ensures the module to deliver the highest-performance positioning solution available, even when GNSS signal is absent or compromised, according to the company.

Equipped with 6-axis sensor MEMs and a powerful GNSS core, the module provides high sensitivity, fast GNSS signal acquisition and tracking with low system integration effort. Moreover, the built-in LNA offers the module with improved RF sensitivity and exceptional acquisition/tracking performances even in weak signal areas.

L26-DR reportedly is able to acquire and track any mix of GPS, GLONASS, BeiDou, Galileo and QZSS signals, which allows accurate navigation in harsh environments such as urban canyons. Compared with using GPS only, enabling multiple GNSS systems generally increases the number of visible satellites, reduces the time to first fix and improves positioning accuracy, especially when driving in rough urban environments.

Designed in an ultra-compact size of 12.2mm × 16.0mm × 2.3 mm, the compact GNSS module also supports other precise positioning technologies, including Differential GPS (RTCM) and SBAS (WAAS/EGNOS/MSAS/GAGAN). The L26-DR is said to be ideal for automotive and industrial applications.
