GPS & GNSS

GPS and GNSS surveying systems deliver centimeter-level positioning accuracy for large-scale site layout, topographic surveys, control point establishment, and machine control applications. Unlike optical instruments, GNSS receivers work in open terrain without line-of-sight constraints — ideal for large earthwork sites, highway projects, and land surveys covering hundreds of acres.

Express Tools carries professional GNSS receivers and complete RTK systems from Topcon, Sokkia, and Trimble — the platforms trusted by land surveyors, civil engineers, and large earthwork contractors. RTK (Real-Time Kinematic) systems deliver sub-2cm positional accuracy in the field using a base station and rover configuration, or via network RTK (NTRIP) subscription services.

Applications include boundary surveying, topographic data collection, construction stakeout, road centerline layout, and integration with machine control systems. Each system is configurable for standalone or networked GNSS operation and compatible with major field data software platforms.
