Battery safety

The Dragonfish base station is powered by lithium polymer batteries. Improper use of these batteries can be dangerous. Please ensure to follow the battery usage, charging and storage guidelines outlined in this document.

Warning

• Only use the battery and charger provided by Autel Robotics. It is prohibited to modify the battery pack and its charger, or use third-party equipment to replace it.
• The electrolyte in the battery is extremely corrosive. If the electrolyte accidentally splashes into your eyes or skin, please wash the affected area with clean water immediately and consult a doctor.

Precautions

1. It is recommended to use the base stations with corresponding frequency bands that comply with local laws and regulations.
2. Do not excessively bend and fold the cables during installation.
3. When installing and placing the base station, make sure that the base station is level with the surface.
4. Use the base station in an open environment free from radio interference. Be sure to turn off other wireless devices in the same frequency band before using it.
5. Make sure that all device antennas are not blocked during use.
6. Use original accessories or accessories certified by Autel Robotics. The use of non-original accessories may cause danger and compromise the system.
7. Ensure that there are no foreign objects or substances (such as water, oil and other liquids, sand, etc.) inside the system.
8. Do not remove any parts installed at the factory by yourself.
9. When using the base station in rain or snow, please ensure that the device is safely covered to prevent damage. Also, pay careful attention when using the base station in weather conditions where there is thunder or lightning.

Introduction

The Dragonfish base station (hereinafter referred to as “base station”) is a high-precision satellite signal receiver that supports GPS, Beidou, Galileo, and GLONASS navigation systems. It has a built-in data transmission system that has been designed to operate in various applications and environments. The Dragonfish RTK base station allows for centimeter-level positioning accuracy, and provides strong anti-magnetic interference capabilities to ensure a smooth and reliable flight, even in areas near power lines and buildings.

Preparation

Charging the battery

To check the battery level, short press (less than second) the power button once.

Charging method

When using the base station for the first time, be sure to fully charge the battery. Please use a dedicated charger to charge the base station.

1. Plug the Type-C power cord into the Type-C port of the base station. The base station will automatically enter the charging mode.
2. When charging, the power indicator of the base station flashes, and the battery power is indicated by means of different colors. When connected to the charging power source, the base station power indicator light is steady green to indicate that it is fully charged.

Turning the base station on/off

Turning on
The base station has two working modes, namely normal mode and disabled RTK mode. Both can be used for different operating scenarios. Follow the instructions below to turn on the base station and enter different working modes.

1. When the base station is off, press and hold the power button for second to enter the normal mode.
2. When the base station is off, press and hold the power button for seconds to enter the disabled RTK mode. The buzzer will beep times and the RTK indicator shows static red.

Turning off
Long press the power button for second to turn off the base station.

RTK indicator description

to adjust the base station to an open area)
Red flashing slowly| Signals from <6 satellites received (very poor signal, it is recommended to adjust the base station to an open area)
Lights off| No RTK signal (abnormal RTK functioning or base station)

How to use the base station

Connection method
When using the normal mode, follow the instructions below.

1. Base station and aircraft frequency
2. Click the base station link button, and the link light will flash.
3. Short press the link button in the battery compartment of the aircraft to enable the aircraft to enter the linking state. During the linking process, the linking light on the aircraft body will flash.
4. Once linking is successful, the linking light on the base station will flash green quickly in second intervals.
5. Connecting the ground station to the base station
6. Power on the base station
7. Turn on the remote control and run the Autel Voyager App, “Settings ->Base Station”. You will be able to see the base station WiFi/hotspot, then enter the password , and wait a few seconds until the Dragonfish base station is displayed on the remote control.
8. Exit the settings interface, enter the mission flight interface, click the gear icon in the upper right corner, enter the settings menu, click “remote control”, and turn on the “use base station connection” option.

Setting up the Dragonfish base station

Choose an open area to set up the base station and allocate a mark on the ground (aligning the center of the tripod with the center of the mark point) so that the base station can be accurately reset after being moved.

1. Open up the tripod, stretch the three leg column to a suitable length, and then tighten the knob at the top to ensure that the tripod is stable.

2. Install the main body of the base station to the tripod and tighten the lock nut on the main body. Ensure that the base station is level and stable.

3. . Install the antenna on the tripod and connect the antenna feeder to the base station antenna port.

NOTE:

• After the tripod is leveled, do not change the position and angle of the tripod or base station, otherwise you may need to level it again.
• Make sure that the surrounding area is open and that there are no obstacles (trees, buildings) nearby that could affect the GNSS signal.
• The installation area of the base station should be at least m away from any high-power radio sources (such as TV stations, microwave stations, etc.), and at least m away from high-voltage transmission lines to avoid electromagnetic fields from affecting GNSS signals.
• There should be no large area of water or objects as these can strongly interfere with the satellite signal reception, impacting the normal functioning of the base station.
• During a flight mission, the base station must not be moved, otherwise it may disconnect from the aircraft, affecting normal operation.

How to use the Dragonfish base station

1. Adjust the base station to a suitable height.
2. Power on the base station and wait for the system to complete initialization.
3. Power on the ground station and aircraft, and make sure that Autel Voyager is running.
4. Enter the mission flight interface, click the gear icon in the upper right corner, enter the settings menu, click “Ground Station”, and ensure that the “Use Base Station Connection” option is turned on.
5. Confirm that the base station RTK indicator is green, indicating that the base station RTK is working properly. Enter the Autel Voyager App mission flight interface, and check that “the ground station is connected to the aircraft” in the upper left status bar. Check that the RTK status in the upper right status bar is FIX, which means the aircraft has entered the RTK positioning mode.
