The G990II high-precision GNSS receiver is a classic work of Hezhong Sizhuang Company. The G990II is equipped with a new generation of baseband chip Tianqin II independently designed and developed by Hezhong Sizhuang. The chip adopts a 55nm manufacturing process, supports 1100 fully compatible channels, and can process baseband chips for "all constellations, all frequency points" satellite signals.

- Multi-constellation and Multi-frequency

With 336/800 channels of GNSS tracking, E800 provides stable and reliable accuracy. All GNSS signals are coming with standard including GPS, BDS, GLONASS, GALILEO, QZSS, IRNSS and SBAS.

- Batteries for Long Time Operation

E800 is equipped with 13600 mAh Li-ion battery. There is no worry for long time field operation up to 15 hours. The USB type-c quick charge promise a full charge within 5 hours.

- MEMS Dynamic Tilt Surveying

Innovation tilt survey solution provides a surprising experience. The sensor is adapted to various of working environments and can be ready within 10 sec. Maximum 60° incline angle ensures a tilt to go survey without stopping your work.

- L-band Atlas

Atlas is a service to provide global precision correction service over L-band satellites. With ATLAS subscription, E800 is able to achieve centimeter accuracy without any base station.

- aRTK

Powered by Atlas, the innovative aRTK technology operates on any Atlas-capable device by enabling it to maintain RTK-level accuracy, availability, and reliability when RTK corrections fail without additional cost.

- 5-watt Internal Radio

The 5-watt internal radio modem extremely extend the working range up to 15Km. User can adjust the radio power between 2w and 5w depending on the demand.

- Colorful Touch Screen

The 1.45” colorful touch screen is viewable in sunlight. The position status is under control with a glimpse. Working mode is settle down by simply sliding the screen.

- Web UI

It is able to view position status, set up working mode, download data and update firmware from Web user interface with any phone, tablet or PC.

- Intelligent Voice

E800 will broadcast voice automatically to remind user the solution status is changed. It is also able to manually broadcast current working mode and solution status by short pressing power button.

- Rugged Design

E800 main body is using magnesium materials to provide strong shock and vibration resistant characteristics. IP67 certification ensures operation in various of tough environments.
