Quectel Wireless Solutions, a global IoT solutions provider, announces the launch of the Quectel QLM29H series of dual-band multi-constellation receivers. Designed for easy integration, the QLM29H combines the LC29H GNSS module with an integrated GNSS patch antenna to simplify RF design. It supports dual-band L1 and L5 signals and provides excellent multipath rejection, especially in challenging environments such as urban canyons where high-precision positioning is critical.
“The Quectel QLM29H receiver series supports use cases from micromobility to agriculture with precise positioning capability,” said Norbert Muhrer, President and CSO of Quectel Wireless Solutions. “The QLM29H helps customers adapt or modernize existing designs by giving them access to dual-band GNSS instead of just L1 signals, provided the legacy product has a simple UART interface. In addition, the receiver offers customers the flexibility to use GNSS as a plug-in option, allowing them to decide whether to integrate it based on their specific requirements.”
The QLM29H receivers support simultaneous reception of global and regional GNSS constellations such as GPS, GLONASS, Galileo, BDS and NavIC as well as QZSS and SBAS. The internal LNA, diplexer and SAW filters improve the sensitivity and anti-interference capability of the receivers. The high-precision positioning capability of the QLM29H makes it perfectly suited for applications such as micromobility, precision agriculture, navigation, insurance telematics and tractor steering systems and enables easy upgrade of existing L1-only systems that have a free RS232 port without having to completely redesign the product.

Designed to reduce time to market, the QLM29H offers features such as dual frequency support, improved 1m accuracy in autonomous mode, and centimeter-level precision in the RTK (real-time kinematics) positioning-capable variant. The Dead Reckoning (DR) feature also helps ensure the module’s superior positioning performance, even in weak signal areas or when GNSS signals are unavailable.
Flexible integration capabilities coupled with a radically simplified RF design for customers make the QLM29H attractive for use cases such as tractor guidance systems and mining. It also offers an alternative to very expensive rugged tablets that have been sold to customers with proprietary software and fully integrated GNSS. The QLM29H can enable off-the-shelf tablets with open source software to support GNSS via a simple four-wire interface.
Quectel further simplifies product design by offering GNSS modules and antennas such as the QLM29H as a pre-integrated package, with customers able to purchase modules and antennas separately if they wish. This helps reduce time to market and ensures the performance of the overall solution.
