SparkFun has introduced a brand new Raspberry Pi-compatible {Hardware} Connected on High (HAT) for anybody needing high-accuracy positioning information by way of World Navigation Satellite tv for pc System (GNSS) reception: The SparkFun GPS-RTK Useless 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 Useless Reckoning (ADR) know-how,” 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 automobile dynamics mannequin, correction information, and GNSS measurements.”

Actual-Time Kinematic (RTK) positioning takes location-tracking to a brand new degree, utilizing commonplace GNSS alerts — together with from the World 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 have been restricted to skilled surveyors and authorities teams,” SparkFun claims. “Because of science, math, and economics, RTK receivers are actually lower than $300.”

The SparkFun GPS-RTK Useless Reckoning pHAT is, as the corporate says, constructed across the u-blox ZED-F9R, giving it 184 GNSS reception channels and help 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 suitable, the corporate says, with the NVIDIA Jetson Nano, Google Coral Improvement Board, and “any single laptop with the two×20 [GPIO] type issue.”

The HAT is just SparkFun’s newest in a string of extreme-precision location-sensing gadgets. 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 Specific, which upgraded the still-earlier RTK Surveyor.

For these desirous to reap the benefits of 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 will want to connect with a base station” with a purpose to obtain the correction information which offers the highest degree of positioning accuracy.

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