The upgrade package also includes three sophisticated C-Scope Radar Extractor & Trackers, which are able to improve the port's radar performance without upgrading radar hardware. This is achieved through the use of advanced signal processing techniques to extrapolate a clearer image from the raw radar signal and is the most effective method of ensuring all targets in the domain can be clearly defined. VOC5060 is a VTS operator workstation and is used as the primary interface to a VTMIS. In addition to providing VTS operators with access to all the information available in the system, together with the ability to control system functions, it also allows for sharing of VTS related data with other applications such as a PMIS (Port Management Information System).
