Quectel L89HA Dual-Band GNSS Module (IRNSS/NavIC-Enabled, L1+L5)

A compact multi-constellation module with L5

The Quectel L89HA is a high-performance GNSS module that supports multiple constellations and two GNSS bands. It can acquire and track GPS, the Indian Regional Navigation Satellite System (IRNSS), GLONASS, BeiDou, Galileo and QZSS signals, including the IRNSS L5 band.

It has an embedded patch antenna and chip antenna, integrated low-noise amplifiers for better sensitivity and DGPS and SBAS (WAAS, EGNOS, MSAS and GAGAN) support.

Specifications and integration

The module measures 25.0 x 16.0 x 6.8 mm and weighs about 8.2 g. It runs from 3.1 to 4.3 V (typically 3.3 V), works from -40 to 85 C and speaks NMEA 0183 over I2C or UART. A multi-tone active interference canceller helps it in electrically noisy places, and Quectel provides SDK commands for configuration. The receiving bands are GPS L1 and Galileo E1 at 1575.42 MHz, IRNSS L5 at 1176.45 MHz, GLONASS L1 at 1602.5625 MHz and BeiDou B1 at 1561.098 MHz. It is RoHS compliant.

This is a bare module, so plan a carrier board with a clean 3.3 V supply and access to its UART or I2C pins. Keep the antenna area clear of metal and place it with a good view of the sky.

Who it suits

Product developers and advanced makers who want an L5-capable GNSS module for trackers, drones and navigation devices, especially in India where IRNSS (NavIC) is available.

Design tips

When you design a carrier board, keep the supply clean with a good decoupling capacitor near the module, give the embedded antenna a keep-out area with no copper or metal nearby, and route the UART or I2C lines away from switching regulators. Test the module on the bench with u-center or a similar tool to watch the satellites, signal strength and dual-band tracking before you commit to a layout.
