SparkFun RTK EVK offers GNSS with centimeter accuracy, WiFi, Bluetooth, 4G LTE Cat 1, and Ethernet connectivity

SparkFun RTK EVK is a fully-enclosed GNSS platform designed for fixed or mobile high-precision positioning and navigation applications with centimeter accuracy thanks to RTK (real-time kinematic) technology implemented with modules from u-blox. About two months ago, Sparkfun introduced the RTK Torch waterproof GNSS surveyor with Unicore UM980 GNSS module with RTK support, ESP32 for WiFi/Bluetooth, and an STM32WLE5C LoRa SoC. The  SparkFun RTK EVK (evaluation kit) may drop LoRa connectivity, but it’s a more versatile platform with WiFi, Bluetooth, Ethernet, and LTE Cat 1 cellular connectivity, besides support for L1 + L2 RTK GNSS with L-Band correction. Sparkfun RTK EVK specifications: GNSS Receiver – u-blox ZED-F9P Concurrent reception of GPS, GLONASS, Galileo, and BeiDou Receives both L1C/A and L2C bands 184-channel u-blox F9 engine Time to First Fix: 25s (cold), 2s (hot) Max Navigation Rate: 20Hz / 25Hz depending on mode Horizontal Position Accuracy: 2.5m without RTK; 0.010m with RTK […]

Affordable RTK GNSS receiver supports USB or/and Ethernet interfaces (Crowdfunding)

HYFIX’s RTK Rover is an affordable, centimeter-accurate RTK (Real-time Kinematic) GNSS receiver with either a USB interface or/and Ethernet connectivity with the latter relying on a Raspberry Pi 4 SBC. As a reminder, RTK relies on traditional GNSS networks like GPS and works with a Base station at a fixed location and a Rover station that can be fitted to a drone or mobile robot in order to determine the position with up to one-centimeter accuracy. The RTK Rover from HYFIX is equipped with a dual-band LC29H GNSS module from Quectel and an onboard IMU sensor that tracks position through dead reckoning when GNSS connectivity is lost. RTK Rover specifications: MiniPCIe card with Dual-Band L1/L5 RTK Receiver (Quectel LC29H) Antenna – External antenna (6x5x2 cm) connected to SMA connector Sensor – IMU Interfaces USB Type-C port for power and serial Interface Ethernet Rover Kit only – Gigabit Ethernet and  USB ports […]

ROCK Base triple-frequency RTK/GNSS base station works with Web3 GEODNET decentralized network

ROCK Robotic has announced the ROCK Base triple-band multi-constellation RTK/GNSS base station that works with the Web3 GEODNET decentralized GNSS reference network, with the solution designed to offer centimeter accuracy to support applications such as civil surveying, high-definition mapping, digital twin creation, and robotic solutions. Real-time Kinematic (RTK) is a relative positioning technique relying on GNSS (GPS,  Galileo, GLONASS, Beidou …) and allowing centimeter positioning accuracy. The technique requires an RTK “Base station” like the ROCK Base and a lower-cost “Rover station” typically attached to a vehicle or drone. For higher accuracy, it’s also possible to use a Network RTK: Network RTK is based on the use of several widely spaced permanent stations. Data from reference stations is combined in a common data processing in a control center. The control center computes corrections for the spatially correlated errors within the network. These corrections are transmitted to the rover. Comparing to […]
