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 and Europe. 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: PointPerfect L-Band correction service for the SparkFun GNSS Correction Data Receiver - NEO-D9S is currently only available in the USA's 48 contiguous states and the European Union shown in the coverage map below. 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.

SparkFun GNSS Correction Data Receiver - NEO-D9S (Qwiic) Product Help and Resources

GNSS Correction Data Receiver (NEO-D9S) Hookup Guide

October 27, 2022

Add GNSS correction data to your high precision GNSS (HPG) receiver with the u-blox NEO-D9S! This tutorial will get you started with the ZED-F9P, NEO-D9S, and the ESP32 IoT RedBoard.

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.
See all skill levels

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

    What is an estimated cost for the Point Perfect service and the Thingverse service ? Also, it sounds like a pain to have to keep entering subscription keys and valid service dates- users would like to set it up and forget it.

      Re. the pricing, please follow this link and click "IoT Location-as-a-Service" and then "PointPerfect":

        Re. the keys: unfortunately there is no set-and-forget option. The key changes every 4 weeks. You can download the current key and the next key together, so you are good for up to 8 weeks. Our L-Band Facet product automates this for you, collecting the keys via MQTT when you are connected to WiFi. There is an example here that you may find useful:
