    Abstract: Techniques are disclosed for systems and methods to provide accurate attitude estimation for a mobile structure. An attitude estimation system includes a logic device in communication with a gyroscope, an accelerometer, and/or a speed sensor. Sensor signals provided by the various sensors are used to determine an estimated absolute coordinate frame relative to the mobile structure, which can be referenced to the Earth's gravity. Angular velocities provided by the gyroscope are transformed to the estimated absolute coordinate frame and used to determine a stabilized attitude estimate for the mobile structure. The stabilized attitude estimate may be displayed to a user, used to calculate a heading or route for the mobile structure, and/or used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.

    Abstract: Techniques are disclosed for systems and methods to provide accurate, low lag, and reliable autopilot autorelease in a hydraulic steering system for mobile structures. A hydraulic steering system includes a logic device configured to communicate with an autopilot pump controller, a control surface reference sensor, an orientation sensor, and/or a gyroscope. Control and sensor signals provided by the pump controller and/or the various sensors are used to selectively enable and/or disable an autopilot release signal. The autopilot release signal enables or disables the autopilot pump controller and/or an autopilot pump, or controls the autopilot pump controller to enable or disable the autopilot pump.

    Abstract: Techniques are disclosed for systems and methods to provide polarization alignment for wireless networking systems. A polarization aligned wireless networking system may include one or more sensors, controllers, user interfaces, and/or other modules mounted to or in proximity to a vehicle. Antennas for each of the electronic devices may be implemented with linear polarization components that can be substantially aligned with a lateral axis of the vehicle. Each electronic device may be implemented with a logic device adapted to use a corresponding antenna to form one or more wireless links between the various electronic devices.

    Abstract: Techniques are disclosed for systems and methods to provide proactive directional control for a mobile structure. A proactive directional control system may include a logic device, a memory, one or more sensors, one or more actuators/controllers, and modules to interface with users, sensors, actuators, and/or other modules of a mobile structure. The logic device is adapted to determine a steering angle disturbance estimate based on environmental conditions associated with the mobile structure, and the steering angle disturbance estimate is used to adjust a directional control signal provided to an actuator of the mobile structure. The logic device may also be adapted to receive directional data about a mobile structure and determine nominal vehicle feedback from the directional data, which may be used to adjust and/or stabilize the directional control signal provided to the actuator.

    Abstract: Techniques are disclosed for systems and methods to provide automatic and substantially continuous calibration for compasses mounted to moving structures. A compass calibration system may include a logic device configured to receive one or more sensor signals and determine a corrected magnetic field based, at least in part, on a measured local magnetic field. The logic device may be adapted to receive an angular velocity, an acceleration, the measured local magnetic field, and/or a speed of a mobile structure; generate stabilized roll and pitch components of an orientation of the mobile structure based, at least in part, on the acceleration and angular velocity; and determine the corrected magnetic field based, at least in part, on the speed, the local magnetic field, the stabilized roll and pitch components, and/or the angular velocity.

    Abstract: Techniques are disclosed for systems and methods to provide wind sensor motion compensation for wind sensors mounted to moving platforms. A wind sensor motion compensation system may include a wind sensor, a wind sensor accelerometer, one or more additional sensors, actuators, controllers, user interfaces, and/or other modules mounted to or in proximity to a vehicle. The wind sensor motion compensation system may be implemented with one or more logic devices adapted to receive sensor signals and determine a sensor-motion compensated wind velocity. The logic devices may be adapted to receive a wind sensor acceleration and a relative wind velocity from a wind sensor, determine a wind sensor velocity from the wind sensor acceleration, and determine a sensor-motion compensated relative wind velocity from the wind sensor velocity and the relative wind velocity.
