Product Description

IG29H is a series of dual-band, multi-constellation GNSS modules that support the concurrent reception of GNSS constellations such as GPS, GLONASS, Galileo, BDS, and QZSS.

Compared to GNSS modules that track only L1 signals, the IG29H series can track a higher number of visible satellites in multi bands, thereby significantly mitigating the multipath effect in deep urban canyons and improving positioning accuracy. By having an internal LNA and diplexer, the module achieves improved sensitivity and anti-interference capability. Featuring dual frequency support, the module delivers enhanced accuracy values of 1 m in autonomous mode and centimeter levels in the RTK capable variants.

Based on the receiver chip using 12 nm technology, the IG29H series provides advanced power management enabling low-power GNSS sensing and position fix, which makes the module an ideal solution for power-sensitive and battery-powered systems.
Featuring high-precision positioning and low power consumption makes the IG29H series perfectly suited for applications such as real time tracking and sharing economy related
