Abstract
Systems are disclosed for navigating a marine vessel with a navigation system that displays a planned route including a set of current and future waypoints. The system has a display and an integrated user input control. A new desired current heading and new future waypoints with associated future headings are provided and a corresponding autopilot navigates accordingly.
Claims20
A system for navigating a marine vessel by way of a first motor coupled to a first portion of the marine vessel and a second motor coupled to a second portion of the marine vessel, the system comprising:
- a display that provides a representation of a planned route of the marine vessel including a plurality of waypoint icons associated with a current waypoint and one or more future waypoints along the planned route, the current waypoint comprising a current position and a current heading of the marine vessel, and the one or more future waypoints each comprising a planned position and a planned heading of the marine vessel along the planned route;
- a user input control integrated with the display and configured to receive a user input to modify the planned route by providing a desired heading for the current waypoint;
- and
- a route control system in communication with the first motor and the second motor, the route control system configured to:
- receive a current position measurement and a current heading measurement for the marine vessel;
- calculate an updated route based on the planned route, the received current position and current heading measurements and the user input of the desired heading for the current waypoint, the updated route comprising an updated current waypoint having the desired heading for the current waypoint;
- and
- generate first and second control signals for the first and second motors, respectively, based at least in part on the updated route, including the desired heading for the current waypoint;
- wherein the display is refreshed to present the updated route.
A system for navigating a marine vessel by way of a first motor coupled to a bow portion of the marine vessel and a second motor coupled to a stern portion of the marine vessel, the system comprising:
- a display that provides a representation of a planned route of the marine vessel including a plurality of waypoint icons associated with a current waypoint and one or more future waypoints along the planned route, the current waypoint comprising a current position and a current heading of the marine vessel, and the one or more future waypoints each comprising a planned position and a planned heading of the marine vessel along the planned route;
- a user touchscreen integrated with the display and configured to receive a user input to modify the planned route by providing a desired heading for the current waypoint and a desired heading for one or more future waypoints, wherein the user input for the desired heading of each of the plurality of waypoint icons comprises a two-point multi-touch gesture on the waypoint icon and rotating the waypoint icon to provide the desired heading for the respective waypoint;
- a control system in communication with the first motor and the second motor, the control system configured to:
- receive a current position measurement and a current heading measurement for the marine vessel;
- calculate an updated route based on the planned route, the received current position and current heading measurements and the user input of the desired heading for the current waypoint and the desired heading for one or more future waypoints, the updated route comprising an updated current waypoint having the desired heading for the current waypoint and one or more updated future waypoints having the desired heading for the one or more future waypoints;
- and
- generate first and second control signals for the first and second motors based at least in part on the updated route;
- wherein the display is refreshed to present the updated route.
