The Spectra Precision ProMark™ 220 GNSS system is the most costeffective dual-frequency network RTK rover. Thanks to the Z-Blade GNSS Centric technology, ProMark 220 makes optimal use of all GNSS signals to deliver fast and stable RTK positions even when GPS coverage is insufficient but other constellations like GLONASS are visible.
