Protocol design for unmanned aerial system (UAS) traffic management (UTM)

An unmanned aerial system (UAS) configured to execute a mission planned by a UAS traffic management (UTM) system, the UAS comprising:

• one or more propellers driven by a motor;
• an antenna;
• and
• a processor operatively coupled to the antenna;
• the antenna and the processor configured to receive a mission planning response message from the UTM, the mission planning response message indicating a sequence of waypoints in an airspace, a dynamic path conforming profile (PCP), and a dynamic required navigation performance (RNP) value for each of the waypoints, the mission planning response message further including configuration information indicating one or more trigger events;
• and
• the antenna and processor further configured to compare at least one RNP value during a time interval to one or more RNP values during one or more previous time intervals to determine if a trigger event of the one or more trigger events occurs;
• the antenna and the processor configured to transmit a path conformance status report to the UTM upon determining that a trigger event has occurred, the path conformance status report indicating conformance to one or more parameters specified in the PCP.
