Dronetag Mini 4G makes your drone visible to other airspace participants and lets you track it in real time. It mounts on any drone regardless of manufacturer.

Mini 4G connects over the cellular network to our cloud service to meet Network Remote ID (NRI) requirements. It also broadcasts identification and position locally to comply with Direct (Broadcast) Remote ID (DRI) rules. Both NRI and DRI transmissions follow the relevant standards: prEN 4709-002 for the EU and ASTM F3411 for the US.

The device includes internal antennas, an all-day battery, and a durable enclosure with a reclosable 3M Dual Lock mount, so it can run standalone and be quickly moved across drones in your fleet. It works hand in hand with the Dronetag Web & Mobile app for setup, monitoring, and updates.

For demanding RF environments, Mini 4G also provides two MMCX connectors to attach external LTE and Bluetooth antennas, improving signal strength and connection reliability.

Nano-SIM slot: Mini 4G also provides a nano-SIM slot. You can insert your own SIM, and the device will use your SIM for LTE connectivity instead of the embedded one.

Dronetag Mini 4G transmits position and identification data adhering to Direct (Broadcast) and Network Remote ID regulations. Its transmission follows the standards outlined in prEN 4709-002 for the EU and ASTM F3411 for the US. Dronetag Mini is officially recognized as a Remote ID solution on the EASA website.

Cellular Coverage​

Three LEDs indicate the status of the device and its components - Positioning (GNSS), Remote ID (RID) and Status (STAT).

• Positioning (GNSS) informs about the current state of the satellite positioning system.
• Remote ID (RID) informs about everything related to the Network & Direct Remote ID functionality.
• Status (STAT) informs about the overall device status.

Device States​

Possible states are the following:

The Mini 4G is a highly customizable piece of hardware to suit your flight's needs. It allows you to configure various device parameters, which will help you optimize the performance and battery usage. Configuration is manageable in the Mobile app via Bluetooth.

General​

• Button flight control is an option (enabled by default) that controls whether the Dronetag Mini 4G button can be used for starting/ending the flight. Disable this option only if you think the button can be accidentally pressed by something inside the drone while it is in flight.
• USB Mode (disabled by default) ensures that the device operates in tandem with the drone's activation. It's crucial to enable this mode only when planning to connect the device directly to your drone and utilize the drone's power source to operate it. Activating USB Mode may affect the device's ability to undergo firmware updates while not connected to USB.
• LED Brightness adjusts the brightness level of the LED indicators.
• Auto Power Off interval defines the idle time (in minutes) after which the device will automatically shut down.
• Flight auto-start is an option (enabled by default) that automatically initiates the flight when the device is ready for the flight (has a GNSS fix and NRI/DRI is set). If you disable this option, a short button press in Flight Ready state is needed to start the flight manually.

🆔 Entering Your Operator ID in the Dronetag App​

Before you fly with your Dronetag device, you need to enter your Operator ID in the app. This ensures full compliance with Remote ID / UAS identification regulations in your region.
We support different formats and rules depending on the region you operate in: EU & Singapore, Japan, USA.

Flights​

• Store flight data is an option (disabled by default) that automatically stores all flight data, such as duration, path and altitude directly on the device. This feature becomes useful when there is a lack of cellular signal and your flight data cannot be shared to cloud or when you decide not to use a Mini 4G without subscription.

• The device has limited storage, so you should download your flight data regularly (Dronetag App → Profile → My devices → Dronetag Mini 4G → Synchronize flights → Follow the steps via the app).

Network Remote ID (Cellular)​

• Enable Network Remote ID - Network Remote ID broadcast service is enabled by default. If you want to turn this option off, navigate to Network Remote ID in Device Configuration and switch off the toggle, save the settings and restart the device.
  This is a necessary step in case you decide to use the Free subscription plan

• Configure bands automatically - when enabled, the device will automatically detect LTE bands based on the device location.

• Selected bands - this option is configurable only when "Configure bands automatically" is disabled. You can manually select your region or country, and the device will use only the LTE bands available for that region. Available options:

  • Europe (bands 1, 3, 7, 8, 20, 28)
  • United Kingdom (bands 1, 3, 8, 20, 28)
  • North America (bands 2, 4, 5, 12, 13, 14, 66, 71)
  • Israel (bands 1, 3, 7)
  • South Korea (bands 1, 3, 5, 8)
  • Japan (bands 1, 3, 8)
  • All bands (enables all supported LTE frequency bands)

• Configure PLMN & APN automatically - when enabled (default), the device automatically detects the Public Land Mobile Network (PLMN) and selects the correct Access Point Name (APN) based on the inserted SIM card and operator profile.

• PLMN code - configurable only if "Configure PLMN & APN automatically" is disabled. Allows you to manually specify the PLMN code (a combination of MCC – Mobile Country Code and MNC – Mobile Network Code) to force the device to connect to a specific mobile network operator.

• Access Point Name (APN) - configurable only if “Configure PLMN & APN automatically” is disabled. Defines the APN used for establishing a data connection to your operator’s network.

Direct / Broadcast Remote ID​

• Static data frequency configures the frequency of the Direct / Broadcast Remote ID messages containing takeoff location, UAS Operator ID, and Aircraft ID.
• Dynamic data frequency configures the frequency of the Direct / Broadcast Remote ID messages with telemetry data.
• LTE Fallback Mode
  • When enabled (default state), the device prioritizes continuous transmission of Direct / Broadcast Remote ID messages. If any issue occurs with the cellular or cloud connection, it will disconnect from the cloud and continue transmitting the Remote ID messages with the possibility to store telemetry data locally (if Flight Store enabled).
  • When disabled, the device prioritizes maintaining a cloud connection - Network Remote ID. Connection issues may cause automatic restarts, which can temporarily interrupt transmission of Direct / Broadcast Remote ID messages and telemetry data recording.

Sensors​

• GNSS input configures which GNSS receiver is used as an input for sending the NRI and Direct / Broadcast Remote ID.

• Internal GNSS mode configures the mode of the internal GNSS receiver. The Full power mode has just a slightly higher power consumption than the Power-saving mode. Therefore, it is recommended to use Full power mode.

• SBAS configuration configures the Satellite-Based Augmentation System (SBAS) to improve GNSS accuracy and reliability.

  • Auto – the device automatically selects the appropriate SBAS system based on the current location.
  • WAAS – enables the Wide Area Augmentation System, primarily covering North America.
  • EGNOS – enables the European Geostationary Navigation Overlay Service, primarily covering Europe.

• Location update rate configures the update and navigation rate of the GNSS receiver in Hz. A higher value means more up-to-date data for Direct / Broadcast / Network Remote ID and consumes slightly more power. Thus 1 Hz is recommended for general use.

• Takeoff position accuracy - specifies the accuracy of the takeoff position data. Please note that high accuracy requirements in non-ideal conditions may prevent the device from obtaining a GNSS fix with the required accuracy, and could therefore prevent the flight from starting.

  • Excellent Precision - Maximum takeoff accuracy. May struggle to get a GNSS fix in non-optimal conditions.
  • Good Precision - Offers high accuracy with a risk of delay in acquiring the GNSS fix.
  • Moderate Precision - A balanced option, providing reliable accuracy and a quicker GNSS fix.
  • Basic Precision - Prioritizes a fast GNSS fix but offers only a basic level of takeoff accuracy.

Device Inputs & Outputs​

• External LTE antenna allows selecting internal or optional external LTE antenna.
• External Bluetooth antenna allows selecting internal or optional external Bluetooth antenna.

Cellular Connectivity​

Settings in this section are country-specific and you shouldn’t change the values unless you know what you are doing. If you change the country, please tap on Configure network automatically and turn the device off and on to find the new cellular settings.

The Mini 4G uses a 3M Dual Lock reclosable fastener to be quickly & safely attached and detached from your drone. The Dual Lock holds firm when mated. The interlocking mushroom-shaped heads slide past each other to close with a snap and peel apart easily when you need to separate them by simply pulling the strips by hand.

Proper Location​

When looking for a suitable location to place the Mini on your drone, you need to watch out for four potential issues.

1. Don't place Mini 4G over a curved surface because it might unsnap during the flight.
2. Don't place Mini 4G on a soft material that can bend during mating (such as plastic covers). The Dual Lock may not hold properly.
3. Don't place Mini 4G over or close to other electrical components such as flight controller, IMU, GNSS antennas, RF transceivers.
4. Don't place Mini 4G in inaccessible locations. You should have the button and all the LEDs always reachable and visible.

Remember, if you put your Mini on top of your drone, you can expect a better GNSS signal. When underneath, a better range for Bluetooth Direct / Broadcast Remote ID + better cellular signal is expected. Therefore, the proper location might also depend on your use case.

Dual Lock Counterpart Installation​

One part of the Dual Lock is already firmly glued to the bottom of your Dronetag Mini device. Besides that, we have supplied you with a self-adhesive counterpart, which must be placed on your drone, and a clean alcohol pad to prepare the surface.

1. Find the proper surface on the drone for the Dual Lock counterpart.
2. Clean the surface with an alcohol cleaning pad.
3. Wait at least one minute to let the alcohol evaporate.
4. Remove the foil from the mating piece and stick it onto the area.
5. Wait five minutes, so the glue hardens.
6. Snap the device into the mating piece on the drone.
7. Ensure the glue on both parts holds firmly by repeatedly removing the device from the drone.

Attaching the Mini 4G with Drone Counterpart​

1. Align the Mini with the Dual Lock counterpart on the aircraft so it is centered.
2. Press the Mini straight down toward the drone until you feel and hear a clear “snap” as the mushroom heads interlock.

Removing Dronetag Mini​

• To detach, peel from one corner of the device and lift steadily until the Dual Lock releases.
• Do not twist or slide the Mini off. Peeling from a corner reduces stress on the adhesive and airframe.

Where to Get a Replacement?​

If you need more counterpart pieces, you can order Dual Lock parts on our e-shop. Alternatively, use your local 3M distributor to order a replacement. If you use an alternative distributor, you must ensure that the Dual Lock counterpart is type 3M SJ4570 and has a proper size.
