SparkFun GNSS-RTK Dead Reckoning Breakout - ZED-F9K (Qwiic) (GPS-18719)
DESCRIPTION
The SparkFun ZED-F9K GNSS Breakout is a high precision, sensor fusion geospatial board with equally impressive configuration options and takes advantage of u-blox's Automotive Dead Reckoning (ADR) technology. The ZED-F9K module provides a highly accurate and continuous position by fusing a 3D IMU sensor, wheel ticks, a vehicle dynamics model, correction data, and GNSS measurements.
SparkFun ZED-F9K GNSS Breakout是一款高精度感測器融合地理空間板，具有同樣令人印象深刻的配置選項，並利用了歐博克斯的汽車慣性導航（ADR）技術。ZED-F9K 模組通過融合 3D IMU 感測器、車輪滴答聲、車輛動力學模型、校正數據和 GNSS 測量結果，提供高度準確和連續的位置。
The ZED-F9K module is a 184-channel u-blox F9 engine GNSS receiver, meaning it can receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations with ~0.2 meter accuracy! That's right, such accuracy can be achieved with an RTK navigation solution when used with a correction source. Note that the ZED-F9K can only operate as a rover, so you will need to connect to a base station. The module supports concurrent reception of four GNSS systems. The combination of GNSS and integrated 3D sensor measurements on the ZED-F9K provide accurate, real-time positioning rates of up to 30Hz.
ZED-F9K模組是一款184通道u-blox F9發動機GNSS接收器，這意味著它可以接收來自GPS，GLONASS，伽利略和北鬥星座的信號，精度約為0.2米！沒錯，當與校正源一起使用時，RTK導航解決方案可以實現這種精度。請注意，ZED-F9K只能作為漫遊車運行，因此您需要連接到基站。該模組支援同時接收四個GNSS系統。ZED-F9K 上的 GNSS 和整合 3D 感測器測量相結合，可提供高達 30Hz 的精確、即時定位速率。
Compared to other GPS modules, this breakout maximizes position accuracy in dense cities or covered areas. Even under poor signal conditions, continuous positioning is provided in urban environments and is also available during complete signal loss (e.g. short tunnels and parking garages). The ZED-F9K is the ultimate solution for autonomous robotic applications that require accurate positioning under challenging conditions.
與其他GPS模組相比，這種突破最大限度地提高了密集城市或覆蓋區域的位置精度。即使在信號較差的條件下，也能在城市環境中提供連續定位，並且在信號完全丟失期間（例如短隧道和停車場）也可用。ZED-F9K 是在具有挑戰性的條件下需要精確定位的自主機器人應用的終極解決方案。
Additionally, this u-blox receiver supports I2C (u-blox calls this Display Data Channel) which makes it perfect for the Qwiic compatibility so we don't have to use up our precious UART ports. 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.
此外，這款 u-blox 接收器還支援 I2C（u-blox調用此顯示數據通道），這使得它非常適合Qwiic相容性，因此我們不必用完寶貴的UART埠。利用我們方便的Qwiic系統，無需焊接即可將其連接到系統的其餘部分。但是，我們仍然打破了0.1“間距的引腳，以防您更喜歡使用試驗板。
The SparkFun ZED-F9K GPS Breakout is also equipped with an on-board rechargeable battery that provides power to the RTC on the ZED-F9K. This reduces the time-to-first fix from a cold start (~26s) to a hot start (~2s). The battery will maintain RTC and GNSS orbit data without being connected to power for plenty of time. The breakout board has five communications ports, four of 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 one Qwiic connnector or broken out pins), and SPI. One SMA connector is included for a secure connection to an antenna.
SparkFun ZED-F9K GPS Breakout還配備了板載可充電電池，可為ZED-F9K上的RTC供電。這將首次修復時間從冷啟動 （~26s） 減少到熱啟動 （~2s）。電池將保持RTC和GNSS軌道數據，而無需長時間連接到電源。分線板有五個通信埠，其中四個同時處於活動狀態：USB-C（枚舉為COM埠），UART1（3.3V TTL），UART2用於RTCM接收（3.3V TTL），I2C（通過一個 Qwiic 連接器或斷開的引腳）和 SPI。包括一個 SMA 連接器，用於安全連接到天線。
U-blox based GPS products are configurable using the popular, but dense, Windows program called u-center. Plenty of different functions can be configured on the ZED-F9K: baud rates, update rates, geofencing, spoofing detection, external interrupts, SBAS/D-GPS, etc. All of this can be done within the SparkFun Arduino Library!
基於U-blox的GPS產品可以使用流行的，但密集的Windows程序進行配置，稱為u-center。ZED-F9K可以配置許多不同的功能：波特率，更新率，地理圍欄，欺騙檢測，外部中斷，SBAS / D-GPS等。所有這些都可以在SparkFun Arduino圖書館內完成！
This product requires an antenna: Be sure to check out the related products/hookup accessories and pick a suitable SMA antenna for your project.
本產品需要天線：請務必查看相關產品/連接配件，併為您的專案選擇合適的SMA天線。
Note: The I2C address of the ZED-F9K is 0x42 and is software configurable. A multiplexer/Mux is required to communicate to multiple ZED-F9K modules on a single bus. If you need to use more than one ZED-F9K module, consider using the Qwiic Mux Breakout.
注意：The I2ZED-F9K 的 C 位址0x42，並且可通過軟體進行配置。需要多路複用器/多路複用器才能在單條總線上與多個 ZED-F9K 模組進行通信。如果您需要使用多個 ZED-F9K 模組，請考慮使用 Qwiic 多路複用器分線。
