QUECTEL New Product Intro: QLM29H GNSS Smart Antenna Receiver, Featuring dual frequency support
The QLM29H is our new GNSS smart antenna receiver.
The QLM29HBAA-GM and QLM29HCAA-GM, collectively referred to as QLM29HxAA-GM, are dual-band, multi constellation smart antenna receivers that support the concurrent reception of global and regional GNSS constellations such as GPS, GLONASS, Galileo, BDS, and NavIC* as well as QZSS and SBAS. Unlike GNSS receivers that track only L1 signals, QLM29HxAA-GM can receive and track a higher number of visible satellites across multiple bands, thereby significantly mitigating the multipath effect in deep urban canyons and improving positioning accuracy.
The internal LNA, diplexer and SAW filters enhance the receivers’ sensitivity and anti-interference capability. Featuring dual frequency support, the receivers deliver enhanced accuracy of 1m in autonomous mode and centimeter level in the RTK-capable variant. The DR function ensures the module’s superior positioning performance even in weak signal areas or when GNSS signals are not available.
The high-precision positioning capability of the QLM29HxAA-GM smart antenna receiver makes it perfectly suited for applications such as micromobility, tractor steering systems, precision agriculture and enables easy upgrading of existing legacy L1 only systems that have a spare RS232 port without complete product redesign.
