What is the remote ID function?

The Remote ID (RID) function is a function that uses Bluetooth 5.x Long Range, Wi-Fi Neighbor Awareness Networking or Wi-Fi Beacon technology to wirelessly broadcast the drone's recognition information to the surrounding area. According to aviation law, it is required to be installed on unmanned aircraft/drones with a takeoff weight of 100g (250g in Europe and the US) or more. The RID signal sent by Remote ID must be in accordance with international standard ASTM F3411-19, be sent at least once per second, and include the following information:

• “registration ID” obtained from the Drone Registration System/Drone UAS Information Platform System (DIPS-REG) operated by the Ministry of Land, Infrastructure, Transport and Tourism Japan (MLIT).
• Serial number specified by the manufacturer
• Unmanned aircraft position/speed information and time information
• Authentication information

Additionally, the RID signal is said to be "desirably receivable from a distance of 300m or more horizontally under ideal circumstances."

When equipped on the drone from the time of purchase

Recently released aerial photography/self-leveling drones takeoff weight over 100g are usually equipped with a remote ID function from the beginning. Please read the product instructions carefully and register in the drone registration system and enable the remote ID function. If the remote ID function is not installed, you will need to install it yourself.

When not equipped with remote ID function

If the remote ID function is not installed, flight methods will be limited. In other words, it is only permitted to fly over areas that have been notified to the Minister of Land, Infrastructure, Transport and Tourism after taking necessary measures, or to fly while moored to the ground with wires.
However, aircraft registered in the drone registration system by June 19, 2022 are exempt from being equipped with the remote ID function. The above restrictions do not apply.

When adding information about the remote ID transmitter later

Open the "UA registration Main menu" in the drone registration system and click "Confirm/Change of the UA Information and the user Information".

A list of registered drones you own will be displayed. Place a checkmark next to the aircraft you want to add information to, and click "Change the UA/user information."

A confirmation screen for the selected aircraft will appear. If there is no problem, click "Enter the UA/user information to be changed".

The screen will look like this. Select "No" if you only want to add information about the remote ID transmitter. This is selected by default.

Scroll through the screen and enter information about your remote ID transmitter.

Scroll further down the screen, click the "Confirm" button at the bottom, and follow the instructions.

Open (DIPS APP) on your smartphone and log in with your drone registration system ID and password.

The app's home screen opens. Tap the "LIST" icon at the bottom center of the screen.

A list of aircraft you have registered in the drone registration system will be displayed. Please look for the aircraft on which you will install the remote ID transmitter. Then tap the "Further Specification" button.
Furthermore, "Remote ID status" is displayed to the right of the registration ID. It shows "none" on a gray background.

A screen like this will appear. Next, prepare the remote ID transmitter.

Connect the power to the remote ID transmitter and put it into remote ID writing mode. For this method, please refer to the manual of the product you obtained.
In the case of "Remote ID mini BVRPT", it will enter remote ID write/update mode for 1 minute after power is connected. While in remote ID writing mode, the LED lights white at 1 second intervals. During this time, complete the following steps.
If you can't do it in time (the LED flashes red), turn the power off and on again, or press and hold the button on the board for 3 seconds.

Bring your smartphone close to the remote ID transmitter and tap the "Write remote ID" button on the (DIPS APP) screen.

You will then be asked for permission to use Bluetooth. Tap "Allow".

The serial number of the nearby remote ID transmitter will then be displayed. Tap this.

The confirmation screen will be displayed. The registration code and serial number of the drone and the serial number of the remote ID transmitter will be displayed. If it is correct, tap "Ok".

Writing of RID information to the remote ID transmitter will begin. Writing takes only a few seconds.

When a screen like this appears, writing is complete. Remove the power from the remote ID transmitter and install it on the drone.

When you look at the (DIPS APP) screen, the "Remote ID status" to the right of the registration ID has changed to "written" with a light blue background.
You will also receive an email titled "[DIPS-REG] Notification of completion of remote ID information registration" from the Civil Aviation Bureau of the Ministry of Land, Infrastructure, Transport and Tourism.
You can also update or delete RID information using the same procedure. If you want to install this remote ID transmitter on another drone, update or delete the RID information.

In the case of "Remote ID mini BVRPT", if the RID information has been successfully written, the device will enter "GPS positioning" mode one minute after connecting the power and the LED will blink in blue. After connecting the power, you need to wait at least 1 minute before you can fly.

Install a remote ID transmitter on your drone

This time I installed a remote ID transmitter on the FPV drone BETAFPV Pavo25 v2 . The part circled in red is the connection part between the 5V BEC connector for the LED light on the aircraft and the power supply for the remote ID transmitter. Both are replaced with 2-pin Micro JST (1.25mm pitch) connectors.
Also, the board surrounded by a red square with a lit blue LED light is the remote ID transmitter. I decided to fasten this together with the battery using Velcro tape.

Attention
During the flight of an FPV drone, the battery output voltage will fluctuate greatly as the motor rotation speed changes. Do not connect additional devices such as remote ID transmitters directly to the battery output terminals. Take the power from the BEC connector on the FC board, or connect an electrolytic capacitor for output smoothing to the battery output terminal.

This is the completed photo. The antennas sticking out on both sides of the back of the Insta360 Go3 camera are the Bluetooth and GPS antennas of the remote ID transmitter.
