2 Product Overview
2.1 Brief Introduction
EA2021 realizes the data transmission between the UAV and the ground station through the 4G
signals. In some areas with the weak or no 4G signals, the UAV fails to receive mission data from the
ground station and cannot operate autonomously. EA2021A-global offline version connects all the
devices in the system to realize the autonomous operation in offline state via the mobile base station
and survey tool.
2.2 Application Scenarios
EA2021A-global offline version is suitable for autonomous operations in areas with weak or no 4G
signal.

3 Introduction to System
Mode 1
Application condition: No survey tool is required with the existing operation plot.
Communication link: Set up the base station. The base station communicates with the UAV in real
time through 2.4G and communicates with the phone through WIFI. The UAV receives the flight
data from the phone and RTK signals from the base station to realize the autonomous flight of the
UAV in offline mode.
5
Mode 2
Application condition: The survey tool is required for plot surveying.
Communication link: Set up the base station. The base station communicates with the survey tool
through 2.4G and the survey tool connects the phone through WIFI. The survey tool receives the
RTK signal for locating and surveying. With the survey tool as the relay, the communication
distances between the phone and the base station, the UAV and the base station can be improved. The
network communication among the base station, survey tool, mobile phone and UAV can realize the
autonomous flight of UAV under the off-line mode
