The LG290P from Quectel is a Quad-Band GNSS Module that supports multiple constellations, including GPS, GLONASS, Galileo, BDS, QZSS, and NavIC. Utilizing multi-mode and multi-frequency RTK algorithms, it delivers fast and reliable RTK high-precision positioning results at 20 Hz, even in complex environments with interference and blockage. The module also supports advanced satellite-based signals, such as L-band, PPP-B2b, QZSS L6, and Galileo HAS E6, to enhance performance. It provides raw GNSS observation outputs and includes protection-level and other integrity detection information, which aids in control decisions for automatic navigation applications.
This GNSS module is equipped with professional-grade interference signal detection and elimination algorithms, that effectively mitigate multiple narrow-band interferences, which significantly improves signal reception performance in complex electromagnetic environments. It also has on-chip storage ECC verification and a secure boot-safe loading mode to ensure firmware safety.
The LG290P offers a variety of interfaces, including UART, SPI, and I2C, and is available in an LGA package that measures 12.2 x 16 x 2.6 mm. It is ideal for high-precision navigation applications such as intelligent robots, UAVs, precision agriculture, surveying and mapping, and autonomous driving.
