Remote ID and Vehicle-to-Vehicle Communications for Unmanned Aircraft System Traffic Management

This article presents the results of experiments on vehicle-to-vehicle (V2V) communications between two Unmanned Aircraft Systems (UASs) and a ground control station conducted in conjunction with UAS Traffic Management (UTM) Technology Capability Level Four (TCL-4) flight tests. For V2V implementation, two UASs were equipped with Dedicated Short-Range Communication (DSRC) radios and experiments were conducted to assess the functionality, capabilities, and limitations of DSRC-based V2V communications. Remote ID is implemented using Globally Unique Flight Identifier (GUFI) assigned to each UAS by the UAS Service Supplier (USS). This article also summarizes the critical issues and recommendations to address them.
