    Powered by field proven CHC core GPS module.


    From long base line static post processing to full RTK operation


    Outstanding accuracy for demanding survey projects


    Integrated rugged design for every day intensive use

The X90 L1/L2 GPS system is designed to enable every surveyor to access to high precision, robust performances and reliable technology but without the common price constraints usually associated with GPS investment. Fully scalable, the X90 GPS various configurations match a wide range of applications, from geodetic post processing to survey grade network RTK.

Competitive and Reliable

The X90 breaks the price barrier for cm accuracy positioning and provides extremely quick return on investment compared to equivalent GPS technology or traditional optical survey equipment.

Oustanding Performances

The X90 is powered by CHC patented GPS L1/L2 core engine and offers outstanding accuracy and fast initialization (30s typical) for topographic surveying and stakeout. In geodetic applications mode, the X90 is able to process long baseline measurement up to 200 km with the use of the Compass Office Software.

Cable Free

Built-in GNSS engine, antenna, Bluetooth® communication and optional GSM/GPRS modules in one single unit.

Compact and lightweight

The size of 20cm×8.5cm (DxH) makes the X90 only weight 1,4 kg. It significantly reduces tiredness of the surveyors in the field work.
