- Model 220 - GNSS Surveying



The Spectra Precision ProMark 220 GNSS system is the most cost-effective 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 GPD coverage is insufficient but other constellations like GLONASS are visible. Very lightweight, with a compact and rugged design, as well as large memory and autonomy, ProMark 220 has been designed for comfortable and productive field use. Its extended wireless communications and embedded GSM/GPRS modem make ProMark 220 a powerful solution suitable for any network RTK application. ProMark 220 is extremely cost-effective, meeting the most demanding requirements for a high-end survey solution. Together with Survey Pro or FAST Survey field software, it enables interoperability with a wide range of survey instruments and accessories to run complete survey jobs.
