Qastor is a precise navigation, piloting and docking software application that was first released in 2000. Although primarily designed as an ECS for piloting operations, Qastor has also proven to be a useful navigation tool in several other fields including Ship Trials, Oil Rig Positioning, Inland River Barges, SPM Approaches, Ferry Operations, Oil and Gas Tanker Approaches and Docking, Patrol Vessels and Tugboat Operations. Using wired or wireless methods, Qastor interfaces to most devices outputting NMEA data strings to AIS transponders/receivers and to the QPS Connect Server, which is currently supplying meteorological data to Qastor users, but also capable of distributing other types of information.
