Implementation of STANAG 4671 Ground Station Standard for Piccolo Command Center

March, 2010

The advent of Unmanned Aircraft Systems (UAS) represents a major change in aviation operations. No longer is the pilot on-board the aircraft to mitigate certain failures or directly monitor the aircraft. Instead the operator is sitting in a remote station relying on a computer screen to provide him the necessary Situational Awareness (SA) to safely conduct his mission. Due to this, it is extremely important that the interface between the operator and the aircraft system display the correct information in a way that is easy for the operator to view and understand. Standardization Agreement (STANAG) 4671 -Unmanned Aerial Vehicles Systems Airworthiness Requirements- (USAR) is the NATO agreement that defines the minimum airworthiness standards for UAS above 150 kg. This standard has been developed to help integrate the UAS operations between NATO member states. USAR addresses the full scope of UAS operations and this research specifically examines its requirements to ground stations. Cloud Cap Technology’s (CCT) Piccolo autopilot provides a powerful tool for controlling UAS and has found use in many civilian and military applications. The Piccolo Command Center (PCC) allows the user to interface with and monitor the state of the unmanned aircraft. However, the ground station does not conform to USAR. A plug-in for the PCC was developed to try to bring it in to as close compliance with USAR as possible. The plug-in is integrated into the standard PCC software through the exposed API such that it can access all of the telemetry. The plug-in monitors and displays this information in accordance with USAR.
