4.1.4 Remote ID

Atom UAV allows to transmit in accordance with ASTM F3411-19/DIN EN 4709-

002, EC 2019/945, EC 2020/1058. The device emits all information through the

Wi-Fi NAN standard and needs to be activated to operate.

The standards allow for multiple types of identifiers. The identifier can be either

based on the Atom UAV serial number (e.g., when used as an “Add-On”), a CAA

registration ID which is validated by the device, or an UTM-assigned UUID.

The other configuration items follow the ASTM and DIN standards, some of which

are optional, depending on the region. Atom UAV implements the full stack of

messages and gives users the option to set all values according to regulations.

Note: Please refer to the local civil aviation authority or legislation to ensure the

requirements are fulfilled.

Note: Atom UAV requires the user to set the correct and valid entries in each

configuration field.

Messages are transmitted immediately after bootup, even if no position is

available. The messages are emitted at a 1 Hz rate using the Wi-Fi NAN message

format. The take-off location is determined as the first available fix. It is therefore

recommended to only power up the Atom UAV at the takeoff location.

Remote ID messages are received only when the transmit function is activated as

well.

Note: The functionality of Remote ID on Atom UAV requires the wireless module

to be enabled (‘Wireless Auto Shut Off’ disabled in Section 4.1.2)

4.1.5 MAVLink

A separate configuration page is available for all functionality related to the

MAVLink integration. Atom UAV supports using an external GNSS solution provided

through the MAVLink interface. For more details on the setup and requirements on

the host, please refer to Section 5.1.

The ports status block on the configuration page shows which port has been

configured through MAVLink, and if Atom UAV receives a heartbeat message

(“Connected” is true). For reference, the System and Component IDs are shown.

Furthermore, a packet counter allows to quickly diagnose the MAVLink data link.

For the configuration of a systematic offset between the GNSS source (e.g., PX4)

and the Atom UAV, a configuration item is available. The procedure is described in

Section 5.1.2.2. The “Timepulse offset valid” flag shows if both Atom UAV and host
