X1 GNSS Receiver

Smallest At The Same Level

Does ultra-versatile mean heavy and bulky? The X1 GNSS receiver delivers the answer. With its Φ133.5 mm × 67 mm hand-palm size and light weight of 870g , the X1 largely lights your burden while keeping a convenient and efficient surveying experience.


Full-Constellation, Fixed in Seconds

Full-constellation tough signal tracking, robust anti-interference and advanced RTK algorithm, X1 takes only a few seconds to get a stable fixed solution even in challenging environments like multipath, tree canopy, city canyons, etc.

Smaller, Lighter

Does ultra-versatile mean heavy and bulky? X1 GNSS receiver gives the best answer. With Φ133.5 mm × 67 mm palmed size and 870g light weight, X1 largely lights your burden in while keeping your best surveying experience.

Over 20hrs Operation

Quitting removable batteries, X1 has optimized charging safety, waterproof capability and internal stacking design based on the internal battery design. 2.5 hours of fast charging via Type-C interface can support over 20 hours continuous working time. It can also be charged via power bank, realize charging on-the-go.

Abundant Transmission

In order to meet different uses, X1 has integrated with NFC/Bluetooth for quick connnection, Type-C USB for charging & upgrade, TNC connector for internal UHF, RS232 serial port to connect with external radio and WiFi/4G.

Ultra-Long Baseline

Supporting both 4G/radio correction data transmission, X1 can reach up to 15km range in enhanced internal UHF mode, 20km range in external mode and over 50km via internal GSM or PDA CORS mode.

60° Tilt, 5s Initialization 

Optimized with the new generation of IMU module, you can easily initialize the IMU in just 5 seconds and start tilt measurements up to 60°. One initialization can meet the accuracy requirement of 2.5cm for the whole work.

Easy Download via Web UI

Accessed via the WiFi of X1, you can easily login the web page for static data download, firmware upgrade, device status check and configuration. 

IP68 Durable Design

No matter it's rainy or dust weather, or you've accidently drop it onto the concrete or into the water, the durable housing of X1 can always protect your device from damage.
