High-Precision GNSS RTK Board for Accurate Positioning & Heading Solution

LOCOSYS RTK-4671-SHPF is a high-precision GNSS RTK board for accurate positioning and heading.  This board offers real-time, cost-efficient and cm-level positioning as well as flexible interfaces, inside great anti-jamming performance (due to multi-tone active interference canceller) for a variety of applications, such as precision navigation, precision agriculture, surveying and UAVs. 


Centimeter-Level Positioning / Support Rover & Base Solutions

The RTK-4671-SHPF is a cost-efficient GNSS RTK board for cm-level positioning and accurate raw measurements output, which can be integrated with autopilots and drone. RTK-4671-SHPF board supports GPS, GLONASS, BDS, 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 both rover and base solutions for those which do not have public CORS network, compact solution and the best-in-class low-power solution for precise positioning application.

The RTK-4671-SHPF can work as an independent positioning system and it can also be integrated with other host devices.  Its popular interface and log/command format make it compatible with most of the OEM boards in market.
