The MR-2 Modular GNSS Receiver provides contractors with flexible, site-independent positioning infrastructure on large-scale construction projects. This dual-function receiver delivers both single and dual GNSS capability with integrated heading functionality, enabling local base station deployment that eliminates dependency on external correction networks and provides immediate RTK accuracy across your jobsite.
Designed for contractors managing extensive project areas where cellular-based RTK corrections are unavailable or unreliable, the MR-2 establishes a local reference network that continuously broadcasts high-accuracy corrections to field receivers and machine control systems. The modular architecture supports multiple input/output options including external radio, Ethernet, and L-Band connectivity, adapting seamlessly to your existing infrastructure and communication preferences.
Construction-grade durability meets demanding specifications. The IP67-rated enclosure protects against dust and water ingress typical of exposed jobsite deployment. Compact dimensions (172x166x49mm) and lightweight construction (950g) simplify installation on masts, towers, or temporary structures without requiring specialized mounting hardware. The external 9-36VDC power input accommodates solar panels, jobsite power systems, or temporary power sources.
Field contractors appreciate the MR-2's flexibility and reliability. Deploy it once at project start and maintain consistent, precise positioning data across all survey and construction operations. The multi-constellation support (GPS, GLONASS, BeiDou, Galileo) ensures robust satellite availability in challenging urban and canyon environments typical of construction sites.
Express Tools stocks the MR-2 and provides installation guidance, configuration support, and technical troubleshooting to ensure your base station delivers optimal performance throughout your project lifecycle.
