Overview
About the MR1
Specifications
Leveraging UniStrong's full industrial chain advantages in satellite navigation and positioning along with multiple proprietary core technologies, the MR1 is a high-precision GNSS positioning and heading receiver tailored for construction machinery.
Built-in mainstream high-precision OEM board with comprehensive support for triple-constellation seven-frequency signals (BDS B1, B2, B3; GPS L1, L2; GLONASS G1, G2), delivering high-precision positioning and heading data; supports both RTK differential and network differential modes.
● Professional Design, Industrial-Grade Quality
Strictly engineered to automotive vibration standards, it delivers superior shock resistance to withstand the demanding operating conditions of construction machinery; the rugged industrial design with an all-metal housing ensures stable operation under extreme high- and low-temperature environments.
