SparkFun GPS-RTK SMA Kit套件 (SMA版本) ZED-F9P（KIT-18292）
The SparkFun GPS-RTK-SMA Kit comes with just what you need to get started using GPS Real Time Kinematics and the u-blox ZED-F9R.
【Kit Includes】清單：
- 1x SparkFun GPS-RTK Dead Reckoning Breakout - ZED-F9R, U.FL版本(Qwiic)
- 1x GNSS Multi-Band Magnetic Mount Antenna - 5m (SMA) 天線

The SparkFun GPS-RTK-SMA Kit comes with just what you need to get started using u-blox's ZED-F9P and GPS Real Time Kinematics. With GPS you are able to know where you are, where you're going, and how to get there anywhere on Earth within 30 seconds. This means the higher the accuracy the better! GPS Real Time Kinematics (RTK) has mastered dialing in the accuracy of their GPS modules to just millimeters, and that's why we had to put it on this kit!
Based on the SparkFun GPS-RTK2 designs, the SparkFun GPS-RTK-SMA raises the bar for high-precision GPS and is the latest in a line of powerful RTK boards featuring the ZED-F9P module from u-blox. The ZED-F9P is a top-of-the-line module for high accuracy GNSS and GPS location solutions including RTK that is capable of 10mm, three-dimensional accuracy. With this board, you will be able to know where your (or any object's) X, Y, and Z location is within roughly the width of your fingernail! The ZED-F9P is unique in that it is capable of both rover and base station operations. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.
We've included a rechargeable backup battery to keep the latest module configuration and satellite data available for up to two weeks. This battery helps 'warm-start' the module decreasing the time-to-first-fix dramatically. This module features a survey-in mode allowing the module to become a base station and produce RTCM 3.x correction data. Based on your feedback, we switched out the U.FL connector and included an SMA connector in this version of the board.／我們在此版本的開發板上替換了 U.FL 連接器，並添加了 SMA 連接器。
The number of configuration options of the ZED-F9P is incredible! Geofencing, variable I2C address, variable update rates, even the high precision RTK solution can be increased to 20Hz. The GPS-RTK2 even has five communications ports which are all active simultaneously: USB-C (which enumerates as a COM port), UART1 (with 3.3V TTL), UART2 for RTCM reception (with 3.3V TTL), I2C (via the two Qwiic connectors or broken out pins), and SPI.
ZED-F9P 的配置選項數量令人難以置信！地理圍籬、可變 I2C 位址、可變更新率，甚至高精度 RTK 解決方案都可以提升至 20Hz。
＊GPS-RTK2 甚至擁有五個可同時使用的通訊連接埠：
USB-C（枚舉為 COM 連接埠）、
UART1（具有 3.3V TTL 電平）、
用於 RTCM 接收的 UART2（帶 3.3V TTL 電平）、
I2C（透過兩個 Qwiic 連接器或斷開的引腳）和 SPI。
We've written an extensive Arduino library for u-blox modules to make reading and controlling the GPS-RTK-SMA over our Qwiic Connect System easy. Leave NMEA behind! Start using a much lighter weight binary interface and give your microcontroller (and its one serial port) a break. The SparkFun Arduino library shows how to read latitude, longitude, even heading and speed over I2C without the need for constant serial polling.
Also included in this kit is the GNSS multiband antenna, ground plate, and a reversible USB-A to C cable. The included antenna features a magnetic base and is designed to receive both the classic L1 and L2 GPS bands. Meanwhile, the ground plate will significantly increase the performance of the included antenna!／該套件還包含一條 GNSS 多頻段天線、接地板、一條可反轉的USB線。隨附的天線帶有磁性底座，可接收經典的 L1 和 L2 GPS 頻段。同時，接地板將顯著提升隨附天線的性能！
