The Emlid Reach RS3 Base and RS4 Rover Surveying Package gives surveyors and construction crews a complete RTK GNSS setup built around two strong receivers working together. The Reach RS3 serves as the correction foundation for the jobsite, while the Reach RS4 brings next-generation rover performance for fast, accurate field measurements. Together, they support topographic surveys, construction layout, boundary marking, as-built checks, utilities mapping, road alignment, and earthwork measurements with centimeter-level precision. The RS4 adds all-band GNSS tracking, 672 channels, L1/L2/L5/L6 support, and fast tilt compensation to help crews measure efficiently in challenging field conditions, including canopy and urban environments.

Designed as a complete surveying package, this setup includes the core accessories needed for base-and-rover operation: an aluminum tripod, bipod, GPS pole, survey pole, receiver cases, USB Type-C cables, antennas, and Pro Survey Plan software. The RS3 supports LoRa correction workflows and NTRIP/RTCM3 connectivity, while the RS4 adds rugged field performance with IP68 protection, 16 hours of RTK rover operation with tilt, and radio connectivity for flexible jobsite conditions.
