social media:
Features
01.1590 channels and 50+ satellites tracking capabilities
02.Tracking all running and planned constellations, including GPS, BDS-2, BDS-3, GLONASS, Galileo, QZSS, IRNSS and SBAS
03.Up to 60°tilt with 2.5 cm accuracy
04.up to 12h continuous work with 10000mAh batteries
05.Support NFC and Bluetooth connection
06.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.
