Features

1590 channels and 50+ satellites tracking capabilities
Tracking all running and planned constellations, including GPS, BDS-2, BDS-3, GLONASS, Galileo, QZSS, IRNSS, and SBAS
Up to 60° tilt with 2.5 cm accuracy
Up to 12h continuous work with 10000mAh batteries
Support NFC and Bluetooth connection
IP67 dust- and waterproof for harsh environments

3rd Generation IMU

By compensating for up to 60° tilt, T20 eliminates challenges associated with surveying concealed or unsafe points and maintains accuracy within 2.5cm. Also, being immune to magnetic disturbance increase reliability

Easy Connection

With advanced NFC, T20 can be connected automatically with a single touch. Dual mode Bluetooth 5.0 allows users to connect at higher distance and low energy standards. Tedious matching is a thing of the past

Stronger Performance

Integrated SinoGNSS K8 high-precision module and third generation IMU, T20 can reach high accuracy even in harsh environments, ensuring the quality of work, and have very low power consumption as well

Longer Battery Life

10000mAh Battery makes 12 hours day&night work possible. QC2.0 helps T20 full-charged in 5 hours, dealing with the worry about power outage
