Extraodinary GNSS
The GNSS unit of G7 is integrated with an advanced SoC which is a chip comes with the advantage of high integration and low power consumption, efficiently suppress the interference signals, and obtain higher quality observation data from satellite constellations.
Combines with powerful GNSS RTK engine with 1598 channels, and the new generation high sensitivity antenna, G7 achieves centimeter precision in seconds while fully tracking GPS, GLONASS, BEIDOU, GALILEO and QZSS signals.
Brilliant design
Single button boot design, one button evokes all RTK operations.The body screen adopts a translucent high-strength panel, which has a stronger visual sense of technology. Plus four color indicator lights, common information is clear at a glance.
Smart unit of tilt measurement
An inbuilt high performance IMU automatic compensator which corrects the coordinates to the pole tip, that assists users quickly and accurately measure or stake out points at will without strict leveling the receiver, it helps surveyors boost productivity by 30 percent. Furthermore, the compensation is still available even though the fixed solution is lost at a short time, surveyors are able to continue the job after fixed solution recovers without initializing again for the lMU module. And the tilt angle range can achieve to 60°.
Unlimited productivity
The new generation of SoC platform gives RTK more stable performance and lower power consumption. The built-in 6800mAh high-performance battery can support more than 15 hours of continuous operation. Featuring with a universal type-c interface, G7 allows to charge the built-in batteries with a PD rapid charger, and support power supply from a power bank to ensure a full-day work.
Both internal memory and web interface are accessed by this type-C interface simultaneously without switching working mode for this port.
