COMPASS2020 (Coordination Of Maritime assets for Persistent And Systematic Surveillance) aims to demonstrate the combined use and seamless coordination of manned and unmanned assets to achieve greater coverage, better quality of information and shorter response times in maritime surveillance operations. By combining innovative technologies and integrating them within the current operational procedures, COMPASS2020 solution ensures long range and persistent surveillance, increasing the situational awareness of Coast Guards and maritime authorities, thus increasing the cost-effectiveness, availability and reliability of the operations. The multidisciplinary consortium consists of fourteen partners from nine countries from research, industry and end-users. The COMPASS2020 Project was launched in May 2019 and finished in October 2021.
