X900 GPS Gnss Receiver Land Survey Equipment Rtk Survey

Solid RTK Performances
The X900 offers greater performances with GNSS functionality. The
GPS+GLONASS feature increases availability in obstructed sky
conditions such as construction sites in urban areas while securing
RTK accuracy and fast initialization.
Competitive and Reliable
The X900 GNSS is the first-choice solution for GPS+GLONASS RTK
surveying at fraction of cost.
Ease of use
Built-in GNSS engine, antenna, Bluetooth® communication and
optional UHF and GSM/GPRS modules in one single unit.
Its optimized power management allows half day of non-stop
RTK work with a single battery.
