Quectel Wi-fi Options has introduced the launch of the Quectel QLM29H vary of dual-band, multi-constellation receivers. Designed for simple integration, the QLM29H combines the LC29H GNSS module and an built-in GNSS patch antenna to simplify RF design. It helps dual-band L1 and L5 alerts, offering multipath mitigation, particularly in difficult environments akin to urban canyons, the place high-precision positioning is vital.
“The Quectel QLM29H vary of receivers help use circumstances from micromobility to agriculture with exact positioning functionality,” stated Norbert Muhrer,the president and CSO at Quectel Wi-fi Options. “The QLM29H helps prospects adapt or modernise current designs by enabling them to entry dual-band GNSS reasonably than solely L1 alerts, offered the legacy product has a easy UART interface. Moreover, the receiver offers prospects with the flexibleness to make use of GNSS as a plug-in possibility, enabling them to decide on whether or not to combine it primarily based on their particular wants.”
The QLM29H receivers help concurrent reception of worldwide and regional GNSS constellations, akin to GPS, GLONASS, Galileo, BDS and NavIC, in addition to QZSS and SBAS. The inner LNA, diplexer and SAW filters improve the receivers’ sensitivity and anti-interference functionality. The high-precision positioning functionality of the QLM29H makes it completely suited to functions akin to micromobility, precision agriculture, navigation, insurance coverage telematics and tractor steering methods and permits straightforward upgrading of current legacy L1 solely methods which have a spare RS232 port with out full product re-design.
Designed to speed up time-to-market, the QLM29H affords options together with twin frequency help, enhanced accuracy of 1 m in autonomous mode and centimeter stage precision within the real-time kinematic (RTK) positioning-capable variant. The lifeless reckoning (DR) operate additionally helps to make sure the module’s superior positioning efficiency, even in weak sign areas or when GNSS alerts should not obtainable.
Versatile integrations, coupled with radically simplified buyer RF design, make the QLM29H interesting to make use of circumstances akin to tractor steering methods and mining. It additionally offers a substitute for very costly ruggedised tablets which had been offered to prospects with proprietary software program and GNSS absolutely built-in. The QLM29H can, by way of a easy 4 wire interface, allow off-the-shelf, customary tablets with open-source software program to help GNSS.
Quectel additional simplifies product design by providing GNSS modules and antennas, such because the QLM29H, as a pre-integrated package deal, though prospects can purchase module and antennas individually if they want. This helps to speed up time-to-market and helps to guarantee the efficiency of the general answer.
The Quectel QLM29H is RoHS compliant, has an working temperature vary of -40 °C to +85 °C and dimensions of 72.0mm x 57.6mm x 22.3mm.
