CHC X20 gps receiver dual frequency gnss rtk survey system trimble rtk 
The CHC X20 L1 GPS receiver is powered by the latest high-performance GPS tracking technology making post processing static and kinematic surveys fast, reliable, and affordable for every surveyor, contractor and engineer.
Competitive and Reliable
Extremely affordable, the X20 GPS system is a “must-have” for a large range of applications from high accuracy surveying to precision mapping.
Easy to use - Static
The X20 is a “one button operation” for static survey. Powering on the unit automatically starts the recording of GPS raw data without any further steps. Operating day and night in any weather conditions, the X20 GPS works up to 9 hours on a single lithium ion battery and can be powered even longer with an external battery.
Cable Free - Kinematic
CHC HDIFF data collection software provides an intuitive yet complete, kinematic survey method and connects directly to the X20 via Bluetooth® to avoid unnecessary cables. HDIFF includes advanced quality control features securing your daily field work.
Compact and Lightweight
A small form factor of 18 cm × 6.5 cm (7 x 2.6 in) and weight of only 0.8 kg (28 oz), including a one-day battery operation, makes the X20 one of the most ergonomic field GPS systems.
KEY FEATURES
1. Competitive and flexible - Cutting edge GPS L1 technology for static and kinematic survey at a fraction of the cost
2. Easy to use - No learning curve “one button” operation mode for static survey
3. Field to finish solution - Easy data transfer and office processing
4. Compact and rugged - Small, lightweight and cable free for intensive field operation
