Quectel LG290P is the world’s first quad-band GNSS module (L1, L2, L5, and E6)

The Quectel LG290P is a quad-band, multi-constellation, high-precision, real-time kinematic (RTK) GNSS module that supports GPS, GLONASS, Galileo, BDS, QZSS, and NavIC constellations. A typical GNSS module like the SparkFun GNSS L1/L5 can receive signals from only one or two frequency bands, but the Quectel module can receive signals from four different frequency bands (L1, L2, L5, and E6) simultaneously and features built-in anti-jamming technology for improved signal reception in challenging environments. All these measures make this chip suitable for high-precision navigation applications like autonomous robots, UAVs, precision agriculture, surveying and mapping, and autonomous driving.

Previously we have written about higher precision GPS modules like the SparkFun RTK EVK module, SparkFun RTK Torch module, the Cavli C17QS IoT GNSS module and much more feel free to check those out if you are interested in those topics.

The company mentions that as the module supports an advanced multi-frequency RTK algorithm it enhances the fix rate by 50% and reduces the time to achieve RTK fix to less than five seconds in challenging environments compared to dual-band solutions.

The module also supports integrity monitoring and authentication information verification which helps ensure the accuracy and trustworthiness of its location data, which is crucial for self-driving vehicles or robotic lawnmowers to make safe decisions. Additionally, the module also includes some security features including ECC check and Secure Boot features. More information about the module can be found on the datasheet and the product page of the module, and some additional information can be found on the press release.

The Quectel LG290P GNSS module is priced at around $82 and is available on DigiKey Mouser and Avnet stores.
