Navmaster ECS is an electronic chart system closely based on the type-approved Navmaster ECDIS software. It provides navigators with the full range of ECDIS navigation tools without the expense of type-approved components. It incorporates the feedback of many navigators into its design and is simple to use within a familiar MS Windows environment. Navmaster ECS is suited for installation on newbuilds and easy to retrofit into existing bridge layouts. It will run on standard PCs interfaced to onboard instruments, in stand-alone and network configurations.
