SparkFun GNSS Correction Data Receiver - NEO-D9S (Qwiic)

The SparkFun NEO-D9S GNSS Correction Data Receiver is a satellite data receiver for L-Band correction broadcast. It can be configured for use with a variety of correction services including u-blox's PointPerfect satellite GNSS augmentation service which provides homogenous coverage in the contiguous USA. With a clear view of the sky especially a clear view to the South it decodes the satellite transmission and outputs a correction stream enabling a multi-band high-precision GNSS receiver (such as the u-blox ZED-F9P) to reach accuracies down to centimeter-level positioning without needing a separate RTK or NTRIP correction!The board is equipped with a USB-C connector so you can hook the board to your laptop and configure the device using u-blox u-center if you want to. We've also equipped the breakout board with two Qwiic connectors so you can connect it quickly and easily to your favorite development board and control it using our sophisticated u-blox GNSS Arduino Library. An SMA connector is included for a secure connection to an L-Band antenna. Power I2C UART1 UART2 and SPI are broken out to 0.1" spaced PTH pins. By connecting the NEO-D9S breakout to one of the ZED-F9P's communication ports you will be able to know where your (or any object's) X Y and Z location is to better than an inch without needing a separate correction source!  Please Note: from March 10th 2025 the u-blox PointPerfect L-Band correction service for the SparkFun GNSS Correction Data Receiver - NEO-D9S will currently only available in the USA's 48 contiguous states shown in the coverage map below. The EU L-Band service is being suspended on that date. More information on PointPerfect can be found here.  Accessories Required: This product requires a suitable L-Band antenna. The ANN-MB-00 GNSS Multiband Antenna (GPS-15192) won't work with Europe's PointPerfect L-Band correction service.Choose a compatible antenna from our Hookup Accessories section below for L-Band correction in Europe. We've carefully selected accessories that work seamlessly with this service. The SparkFun Qwiic Connect System is an ecosystem of I2C sensors actuators shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch 4-pin JST connector. This reduces the amount of required PCB space and polarized connections mean you can’t hook it up wrong. Get Started with the SparkFun NEO-D9S GNSS Correction Data Receiver Guide
