Description

  1. Multi-constellation and Multi-frequency

With 800 channels of GNSS tracking, EA301 provides stable and reliable accuracy. All GNSS signals are coming with standard including GPS, BDS, GLONASS, GALILEO and SBAS.

  1. L-band Atlas

Atlas is a service to provide global precision correction service over L-band satellites. With ATLAS subscription, EA301 is able to achieve centimeter accuracy without any base station.

  1. Wireless Communication

Build-in WIFI and Bluetooth models make it more convenient for remote control and data output.

  1. 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.

  1. Rugged Design

EA301 main body is using aluminum alloy materials to provide strong shock and vibration resistant characteristics. IP67 certification ensures operation in various of tough environments.
