SparkPNT GNSS Flex modules are plug-in boards featuring different GNSS receivers. They are designed to be easily swapped for repairs and pin-compatible for upgrades. The boards have two 2x10-pin, 2mm pitch female headers connecting to carrier boards. For the LG290P GNSS receiver, these pins will break out the UART (x3) and I2C (Feature is still under development) interfaces, along with the PPS and event signals using a standardized pinout.

This SparkPNT GNSS Flex module features the Quectel LG290P GNSS receiver. The LG290P module is a quad-band, multi-constellation, high-precision, RTK GNSS receiver. The module can simultaneously receive signals from the L1, L2, L5, and L6/E6 frequency bands of the GPS, GLONASS, Galileo, BDS, QZSS, and NavIC GNSS constellations. In addition, the module supports SBAS augmentation systems (WASS, EGNOS, BDSBAS, MSAS, GAGAN, and SDCM), PPP services (Feature is still under development) (BDS PPP-B2b, QZSS CLAS, MADOCA-PPP, and Galileo HAS), RTCM, and RTK corrections for precision navigation with a fast convergence time and reliable performance.

The built-in NIC anti-jamming unit provides professional-grade interference signal detection and elimination algorithms, effectively mitigating multiple narrow-band interference sources and significantly improving signal reception performance in complex electromagnetic environments. Additionally, the embedded algorithms ensure reliable positioning in complex scenarios such as urban environments and deep tree cover.

Note: The module currently supports only the UART interfaces. The corrections for some of the PPP services may not have been implemented yet.
