E300 Pro

Full-featured RTK Receiver

The eSurvey E300 Pro is a fully functional GNSS receiver with an extremely compact design by eSurvey GNSS. With its high-performance GNSS board, it can track all present constellations and satellites. The GNSS, Wi-Fi, Bluetooth, and GSM four-in-one antenna, stable data transmission, RTK Aid, and IMU function, make it suitable for all surveying applications.

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.
