A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.
They are electronic navigation instruments that use a rotating antenna to sweep a narrow beam of microwaves around the water surface surrounding the ship to the horizon, detecting targets by microwaves reflected from them, generating a picture of the ship's surroundings on a display screen.
A typical shipboard ARPA/radar system. A marine radar with automatic radar plotting aid (ARPA) capability can create tracks using radar contacts. [1] [2] The system can calculate the tracked object's course, speed and closest point of approach [3] (CPA), thereby knowing if there is a danger of collision with the other ship or landmass.
For example, a device with an accelerometer can detect rotation from vertical to horizontal state in a fixed location. As a result, accelerometers are primarily used for simple motion sensing applications in consumer devices such as changing the screen of a mobile device from portrait to landscape orientation.
Therefore, the majority of these types of devices are either water resistant or waterproof. Marine electronics devices include chartplotter , marine VHF radio , autopilot and self-steering gear , fishfinder and sonar , marine radar , satellite navigation device , fibre optic gyrocompass , satellite television , and marine fuel management .
Motion tracker can refer to: Motion detector , a device that utilizes a sensor to detect nearby motion Motion capture , the process of recording the movement of objects or people

Motion compensators are usually placed between a floating object and a more stationary object, such as a vessel or a structure fixed to the seabed. Most general motion compensators will compensate for movement in all directions The simplest motion compensator is the anchor chain of a ship. Not only does the anchor prevent the ship from drifting ...
