Dynamic positioning (DP) is a computer-controlled system to automatically maintain a vessel's position and heading by using its own propellers and thrusters. Position reference sensors, combined with wind sensors, motion sensors and gyrocompasses , provide information to the computer pertaining to the vessel's position and the magnitude and ...
A local positioning system (LPS) is a navigation system that provides location information in all weather, anywhere within the coverage of the network, where there is an unobstructed line of sight to three or more signaling beacons of which the exact position on Earth is known.
Display PostScript, an on-screen display system; Dynamic positioning system, a means to automatically maintain a ship's position and heading by using her own propellers and thrusters; DPS protocol, a quantum key distribution protocol; DPS (Data Processing System), the designation of several lines of computer in the List of Groupe Bull products
Healy has a Dynamic Positioning System (DPS) that uses her 2200-horsepower Omnithruster Bow Thruster system, which aids in navigation and station keeping during science operations. [7] Her flight deck is capable of landing both of the Coast Guard's helicopter airframes, and attached is a hangar that can house 2 Eurocopter HH-65 Dolphin helicopters.
Since the drillship is also a vessel, it can easily relocate to any desired location. Due to their mobility, drillships are not as stable compared to semi-submersible platforms. To maintain its position, drillships may utilize their anchors or use the ship's computer-controlled system on board to run off its dynamic positioning. [10]
Geopositioning uses various visual and electronic methods including position lines and position circles, celestial navigation, radio navigation, radio and WiFi positioning systems, and the use of satellite navigation systems. The calculation requires measurements or observations of distances or angles to reference points whose positions are known.
IMR vessels are designed to continue operations in harsh weather conditions. They are equipped with IMO Class II or Class III Dynamic Positioning Systems and have the latest technology on board. The vessels usually have a large deck area, used for the carriage of auxiliary equipment, spools, containers, etc.
Differential Global Positioning Systems (DGPSs) supplement and enhance the positional data available from global navigation satellite systems (GNSSs). A DGPS can increase accuracy of positional data by about a thousandfold, from approximately 15 metres (49 ft) to 1–3 centimetres ( 1 ⁄ 2 – 1 + 1 ⁄ 4 in).
