The purpose of the PASSport (Operational Platform managing a fleet of semi-autonomous drones exploiting GNSS high Accuracy and Authentication to improve Security & Safety in port areas) is to engineer and qualify a solution extending situational awareness to improve safety and security in port areas. The need comes from the directive 2005/65/CE asking to complement surveillance systems for all of the port area, in order to ensure a high and equal level of safety and security for all European ports. Around one thousand European ports fall within the scope of the directive. As a consequence, PASSport responds to the needs expressed by port authorities, harbour master and border control authorities which are active parties in the consortium and will be directly involved in the definition of the proposed solutions. Indeed, the proposed solution is about to complement already operational platforms extending the surveillance perimeter using a fleet of drones to provide innovation and operational support to the safety and security aspects of daily operations with particular attention to:
