SparkPNT GNSS Flex Module - LG580P

Determine your project's precise position and orientation with the SparkPNT GNSS Flex Module - LG580P. This advanced module is engineered for high-performance navigation, delivering both centimetre-level RTK accuracy and real-time heading data in a single package. It's the ideal engine for robotics, precision agriculture, and autonomous vehicle applications.

As part of the SparkPNT Flex ecosystem, this module is designed to be easily swappable for repairs or future upgrades. It connects to your carrier board via standardized 2x10-pin headers, breaking out its triple UARTs, I²C* interface, and key timing and status signals.

Precision RTK & Heading in One Module

At the heart of this pHAT is the LG580P, a high-performance receiver that provides a complete navigation solution for dynamic applications.

• RTK + Heading: Delivers not only centimetre-level position accuracy but also high-precision attitude (orientation) data, crucial for autonomous navigation and control.
• Quad-Band & Multi-Constellation: Simultaneously receives signals from the L1, L2, L5, and L6/E6 bands across all major constellations (GPS, GLONASS, Galileo, BDS, QZSS, and NavIC) for fast convergence and performance even in challenging scenarios like urban canyons or deep tree cover.
• Advanced Anti-Jamming: Built-in algorithms detect and mitigate interference, ensuring reliable operation in complex electromagnetic environments.

With a high update rate of up to 20 Hz for both position and heading, the LG580P is perfect for high-speed robotics and vehicle control systems. Its versatility is further enhanced by broad support for standard RTK/RTCM corrections, a wide range of SBAS augmentation systems (WAAS, EGNOS, BDSBAS, MSAS, GAGAN, KASS, ASECNA, SouthPAN, and SDCM), and PPP services* (BDS PPP-B2b, QZSS CLAS, MADOCA-PPP, and Galileo HAS*).

This product requires an external antenna and a GNSS Flex carrier board. Users should have two options for connecting an external GNSS antenna to their GNSS receiver.

• The GNSS Flex Module has a U.FL connector for an external antenna.
• For a sturdier connection, an SMA connector on a GNSS Flex pHAT carrier board can be utilised. Users can simply jumper the U.FL connectors between the SparkPNT GNSS Flex Module and the carrier board with a short U.FL cable.

*According to Quectel, support for the I²C interface is still under development and will be made available through a future firmware update. Additionally, the corrections for some of the PPP services (like HAS E6) have not been implemented yet.
