The duties performed by Navy operations specialists include: [1] Operate a variety of computer-interfaced detection, tracking and height-finding radars; Plot a ship's position, heading, and speed, using computerized or manual trigonometric methods using a Maneuvering Board (MOE Board)
Blue force tracking (BFT) systems consist of a computer, used to display location information, a satellite terminal and satellite antenna, used to transmit location and other military data, a Global Positioning System receiver (to determine its own position), command-and-control software (to send and receive orders, and many other battlefield support functions), and mapping software, usually ...
The AN/SPY-1 [a] is a United States Navy passive electronically scanned array (PESA) 3D radar system manufactured by Lockheed Martin, and is a key component of the Aegis Combat System. The system is computer controlled and uses four complementary antennas to provide 360-degree coverage.
The AN/MPQ-53 at the heart of the system is known as the "Phased Array Tracking Radar to Intercept on Target," [6] which is a backronym for "Patriot". In 1984, the Patriot system began to replace the Nike Hercules system as the U.S. Army's primary high to medium air defense (HIMAD) system and the MIM-23 Hawk system as the U.S. Army's medium ...
The Transit system, also known as NAVSAT or NNSS (for Navy Navigation Satellite System), was the first satellite navigation system to be used operationally. The radio navigation system was primarily used by the U.S. Navy to provide accurate location information to its Polaris ballistic missile submarines, and it was also used as a navigation system by the Navy's surface ships, as well as for ...
The Navy was forced to halt the contract in response to a challenge by Lockheed. [9] Lockheed officially withdrew their protest in January 2014, [10] allowing the Navy to lift the stop work order. [11] In March 2022, Raytheon announced a $3.2B contract to outfit every new surface ship in the US Navy with the SPY-6 family of radars. [12] [13]
A second system continuously reads the data in the track files from memory, and displays this on the radar as a series of annotated icons. Unlike the straight tracking mode, TWS radars have to solve an additional problem of recognizing whether each target discrimination/detection defines a new target or belongs to already tracked targets.
