With the Survey Grade RTK Kit for the XGRIDS L2 Pro scanner, you get a reliable satellite signal even in challenging conditions. You receive centimeter-accurate RTK data supported by all major satellite systems: GPS, GLONASS, Galileo, and BeiDou.

Thanks to advanced antenna technology and a robust design, the kit delivers reliable results under any conditions — ideal for professional surveying, construction projects, and precise 3D modeling.

Compared to standard RTK, the Survey Grade Kit offers significantly improved performance for professional applications. Notably, the antenna axis ratio ≤ 3 dB ensures higher signal quality, and the maximum gain of 5.5 dBi (vs. 2.8 dBi for standard RTK). While standard RTK is suited for general applications, Survey Grade RTK is designed specifically for high-precision surveying and demanding 3D scanning projects.
