Naval Electronic Systems Command
The Naval Information Warfare Systems Command (NAVWAR), based in San Diego, California, is one of six SYSCOM Echelon II organizations within the United States Navy and is the Navy's technical authority and acquisition command for C4ISR (Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance), business information technology and space systems. Echelon II means that the organization reports to someone who, in turn, reports directly to the Chief of Naval Operations on the military side. From a civilian perspective, NAVWAR reports to the Assistant Secretary of the Navy ( RDA). The command was formerly known as Space and Naval Warfare Systems Command (SPAWAR) and was renamed in June 2019 to better align its identity with its mission. NAVWAR supports over 150 programs managed by the Program Executive Office (PEO) for Command, Control, Communications, Computers and Intelligence (C4I), as well as the programs of PEO for Enterprise Information Systems ...

United States Navy Systems Commands
The systems commands, abbreviated as SysCom or SYSCOM, are the materiel agencies of the United States Department of the Navy, responsible for the design, construction, and maintenance of military systems such as ships, aircraft, facilities, and weapons. The systems commands replaced the Navy bureau system in 1966 and report to the Assistant Secretary of the Navy for Research, Development and Acquisition. The current Navy systems commands are: *Naval Sea Systems Command (NAVSEA) *Naval Air Systems Command (NAVAIR) * Naval Information Warfare Systems Command (NAVWAR) (formerly SPAWAR), * Naval Facilities Engineering Systems Command (NAVFAC) *Naval Supply Systems Command (NAVSUP) *Marine Corps Systems Command (MCSC) The Office of Naval Research is sometimes grouped with the systems commands, although it has a different mission geared towards scientific research rather than weapon systems development and acquisition. Function and organization Each of the systems commands provides f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Electronics Laboratory
The U.S. Navy Electronics Laboratory (NEL) was created in 1945, with consolidation of the naval radio station, radar operators training school, and radio security activity of the Navy Radio and Sound Lab (NRSL) and its wartime partner, the University of California Division of War Research. NEL’s charter was “''to effectuate the solution of any problem in the field of electronics, in connection with the design, procurement, testing, installation and maintenance of electronic equipment for the U.S. Navy.''” Its radio communications and sonar work was augmented with basic research in the propagation of electromagnetic energy in the atmosphere and of sound in the ocean. History In November 1945, the Navy Radio and Sound Lab was renamed as Navy Electronics Laboratory. 80% of the Point Loma Military Reservation evolved into the Naval Electronics Laboratory Center (NELC) at the end of World War II. In turn NELC was merged into the Naval Ocean Systems Center (NOSC) in 1977. This eve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NAVWAR Space Field Activity
The NAVWAR Space Field Activity (NSFA) is one of three Echelon III activities under the Naval Information Warfare Systems Command (NAVWARSYSCOM) of the United States Navy, co-located with the National Reconnaissance Office (NRO) in Chantilly, Virginia Chantilly is a census-designated place (CDP) in western Fairfax County, Virginia, United States. The population was 24,301 as of the 2020 census. Chantilly is named after an early-19th-century mansion and farm, which in turn took the name of an .... The activity was established to coordinate naval space and warfare systems activities within the National Reconnaissance Office. NSFA personnel provide naval warfare and acquisition expertise to national reconnaissance programs, coordinate naval space research, development, and acquisition activities with those same national reconnaissance programs, and provide and coordinate training and tools to enable the fleet to use national space capabilities.

United States Department Of Defense
The United States Department of Defense (DoD, USDOD, or DOD) is an United States federal executive departments, executive department of the federal government of the United States, U.S. federal government charged with coordinating and supervising the six U.S. armed services: the United States Army, Army, United States Navy, Navy, United States Marine Corps, Marines, United States Air Force, Air Force, United States Space Force, Space Force, the United States Coast Guard, Coast Guard for some purposes, and related functions and agencies. As of November 2022, the department has over 1.4 million active-duty uniformed personnel in the six armed services. It also supervises over 778,000 National Guard (United States), National Guard and reservist personnel, and over 747,000 civilians, bringing the total to over 2.91 million employees. Headquartered at the Pentagon in Arlington County, Virginia, just outside Washington, D.C., the Department of Defense's stated mission is "to provid ...

Communication Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications satellites is to re ...

Narrowband
Narrowband signals are signals that occupy a narrow range of frequencies or that have a small fractional bandwidth. In the audio spectrum, ''narrowband sounds'' are sounds that occupy a narrow range of frequencies. In telephony, narrowband is usually considered to cover frequencies 300–3400 Hz, i.e. the voiceband. In radio communications, a narrowband channel is a channel in which the bandwidth of the message does not significantly exceed the channel's coherence bandwidth. In the study of wired channels, ''narrowband'' implies that the channel under consideration is sufficiently narrow that its frequency response can be considered flat. The message bandwidth will therefore be less than the coherence bandwidth of the channel. That is, no channel has perfectly flat fading, but the analysis of many aspects of wireless systems is greatly simplified if flat fading can be assumed. Two-way radio narrowband Two-Way Radio Narrowbanding refers to a U.S. Federal Communicatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Military
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. Militaries are typically authorized and maintained by a sovereign state, with their members identifiable by a distinct military uniform. They may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of a military is usually defined as defence of their state and its interests against external armed threats. In broad usage, the terms "armed forces" and "military" are often synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include other paramilitary forces such as armed police. Beyond warfare, the military may be employed in additional sanctioned and non-sanctioned functions within the state, including internal security threats, crowd control, promotion of political agendas, emergency services and reconstruct ...
