Gain a competitive edge with the Easynavtech R7GNSS Receiver. The R7 is equipped with advanced technology to make sure you havemaximum productivity in the field. The durable IP67 design makes it possible to work in tough environments. Combining 4G GSM modem,internal radio (Rx only), RTK Aid function and 60°inclination IMU function, the R7 is the best choice for a rover station receiver.
Lightweight Design:
Easy to Carry
Easily carry it in various complex environments and use it in any rover station scenarios, benefitting from its lightweight and compact design.
Web UI
It allows users to view position status, set up working mode, download data, and update firmware from the Web user interface with any smartphone, tablet, or PC.
Integrated RX Radio
The built -in Global 4G Network and RX radio module allows the E200 to work perfectly as a rover station.
Max 60° Tilt Survey: A Different Way of Working
Quickly measure accurate points while standing or walking without leveling the pole. Concentrate on where the pole tip needs to go, which is especially useful during a stakeout.
E a s i l y s t a r t a s u r v e y i n environments that are hard to reach, such as building corners and slopes. 
No longer worry about the move ment o f the pol e when measuring, provided that the pole tip is stationary.
RTK Aid Function:
Uninterrupted Work
Work without interruption even when RTK corrections fail, powered by our RTK aid function.
Multi-constellations and
Multi-frequency
With 1408 channels of GNSS tracking, the R7 provides stable and reliable accuracy . All GNSS signals can be tracked, including GPS, BDS, GLONASS, GALILEO and QZSS.
