About the E300pro GNSS Receiver.
The E300 Pro is eSurvey's full-featured RTK GNSS receiver in an unusually compact, low-profile body that suits pole surveying, vehicle mounting and machine control alike. It combines an 800-channel multi-constellation engine with a built-in transmit-and-receive UHF radio, a global cellular modem, 60 degree MEMS tilt and L-Band Atlas correction support, so it holds a fixed solution across a wide range of conditions.
A rugged magnesium-alloy, IP67 housing shrugs off knocks and vibration, while aRTK bridging keeps RTK-level accuracy alive when correction links briefly drop. One receiver that can base, rover or ride on a vehicle.
Built to make the job faster.
Full base or rover
A built-in transmit-and-receive UHF radio in a compact body lets the E300 Pro run as either a base or a rover, covering the full survey workflow from one unit.
Calibration-free 60 degree tilt
eSurvey's tilt solution is ready in about 10 seconds and works up to 60 degrees, so you measure tilted points without levelling the pole.
L-Band Atlas correction
With an Atlas subscription the E300 Pro reaches centimetre accuracy worldwide over L-Band satellites, with no base station required.
aRTK bridging
aRTK maintains RTK-level accuracy and reliability when conventional corrections fail, keeping crews productive at no extra cost.
Rugged magnesium build
A magnesium-alloy body gives strong shock and vibration resistance, IP67 sealing, and survives a 2 m drop onto concrete.
All-day battery
A 6,800 mAh battery delivers up to 12 hours of work, with a battery LED check by a single button press even when the unit is off.
