SparkFun Locates Your Raspberry Pi to Centimeter Precision with Its GPS-RTK Lifeless Reckoning pHAT



SparkFun has introduced a brand new Raspberry Pi-compatible {Hardware} Hooked up on High (HAT) for anybody needing high-accuracy positioning information through International Navigation Satellite tv for pc System (GNSS) reception: The SparkFun GPS-RTK Lifeless Reckoning pHAT.

“The SparkFun ZED-F9R GPS pHAT is a excessive precision, sensor fusion GPS board with equally spectacular configuration choices and takes benefit of u-blox’s Automotive Lifeless Reckoning (ADR) expertise,” the corporate explains of its newest launch. “The ZED-F9R module offers a extremely correct and steady place by fusing a 3D IMU sensor, wheel ticks, a car dynamics mannequin, correction information, and GNSS measurements.”

Actual-Time Kinematic (RTK) positioning takes location-tracking to a brand new degree, utilizing customary GNSS indicators — together with from the International Positioning System (GPS) constellation — plus a stream of correction information to ship centimeter-level positioning. “RTK-capable GPS receivers was 1000’s of {dollars} and had been restricted to skilled surveyors and authorities teams,” SparkFun claims. “Due to science, math, and economics, RTK receivers are actually lower than $300.”

The SparkFun GPS-RTK Lifeless Reckoning pHAT is, as the corporate says, constructed across the u-blox ZED-F9R, giving it 184 GNSS reception channels and assist for GPS, GLONASS, Galileo, and BeiDou constellations. The module is mounted on a HAT-format board with Qwiic connector and USB Sort-C, together with a 40-pin general-purpose enter/output (GPIO) header designed for connection to a Raspberry Pi — but in addition appropriate, the corporate says, with the NVIDIA Jetson Nano, Google Coral Improvement Board, and “any single pc with the two×20 [GPIO] type issue.”

The HAT is barely SparkFun’s newest in a string of extreme-precision location-sensing units. Again in June the corporate unveiled the RTK Reference Station, described as its “most succesful” GNSS receiver and logger but; again in 2021 the corporate confirmed off the RTK Categorical, which upgraded the still-earlier RTK Surveyor.

For these desirous to benefit from the HAT’s centimeter-level precision, although, there is a catch: “The ZED-F9R can solely function as a rover,” SparkFun says of the module’s capabilities, “so you’ll need to hook up with a base station” as a way to obtain the correction information which offers the highest degree of positioning accuracy.

The SparkFun GPS-RTK Lifeless Reckoning pHAT is now obtainable on the SparkFun retailer for $289.95 earlier than quantity reductions.
