this is a bandwidth efficient way to update the OPEN_DRONE_ID_SYSTEM message data when there is limited uplink bandwidth. Testing on real vehicles shows that with RFD900x radios at an air data rate of 125kbit/s with OPEN_DRONE_ID messages with 1Hz update (as required by FAA RemoteID standard) that there is significant impact on the ability of the GCS to give commands to the flight controller. For example, I got a high degree of packet loss in downloading parameter pre-flight, and many/most in-flight commands failed from the GCS.
By using this message we can use the minimum required bandwidth for updating operator location while remaining FAA RemoteID standard compliant
