Description
Overview
Power Indicator: An Intelligent Hint of Working Time
Quickly check the remaining battery power in real time and figure out the working time without data loss.
Integrated Tx/Rx UHF Modem in a Compact Design
The built-in transceiver radio modem in the compact design of the E300 Pro makes it a full-featured and portable GNSS receiver that works as either base or rover station.
Rugged Design: Better Resistance to Shock and Fall
Use it for many years, for it is strongly made and capable of withstanding rough handling.
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 E300 Pro provides stable and reliable centimeter-level positioning accuracy in real-time to suit any field data collection applications. All GNSS signals are supported, including GPS, BDS, GLONASS, GALILEO, QZSS， SBAS, L-Band and IRNSS.
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.
- Easily start a survey in environments that are hard to reach, such as building corners and slopes.
- No longer worry about the movement of the pole when measuring, provided that the pole tip is stationary.
