RTK Board



High-Precision GNSS RTK Dead Reckoning Solution for Smart Driving & Lane Level Navigation

LOCOSYS RTK-4671-SHDR is a high-precision GNSS RTK solution targeting for the smart driving and lane level navigation markets. The newly designed LOCO II engine architecture is optimized to offer a seamless experience in dense urban canyons. The RTK-4671-SHDR takes the shortest time to fix position and continues to work wherever they are.


Centimeter-Level Positioning & Dead Reckoning / Support Rover

RTK-4671-SHDR is a cost-efficient GNSS RTK board for cm-level positioning and accurate raw measurements output, which can be integrated with autopilots and inertial navigation units. RTK-4671-SHDR board supports GPS, GLONASS, BeiDou, GALILEO, QZSS and SBAS constellations to improve the continuity and reliability of the RTK solution even in harsh environment.  It features powerful compatibility with other GNSS boards in the market by flexible interfaces, smart hardware design and popular log/command formats adopts Real Time Kinematics (RTK) technology with the correction data from CORS network.  It also supports rover absolutions for those which do not have public CORS network, compact solution and the best-in-class low power solution for precise positioning application.


RTK-4671-SHDR is a single-band multi-system with an ARM base processor; RTK-4671-SHDR not only supports GPS, GLONASS, BeiDou, GALILEO, QZSS and SBAS, but also has a flash memory, TCXO, RTC crystal, LNA and SAW filter, and embedded MEMS sensors (6-axis accelerometers + gyros). The high-precision Positioning/Dead Reckoning receiver offers centimeter-accurate positioning and heading with low-power consumption. LOCOSYS ADR/UDR software includes features to receive and use data from the built-in sensors along with external signals for wheel speed and Forward/Reverse direction.  The vehicle signals are used to provide a high level of accuracy in the navigation solution.
