MMSI
A Maritime Mobile Service Identity (MMSI) is effectively a maritime object's international ''maritime telephone number'', a temporarily assigned UID issued by that object's current flag state (unlike an IMO number, which is a permanent global UID). An MMSI comprises a series of nine digits, consisting of threMaritime Identification Digits(country-codes), concatenated with a specific identifier. Whenever an object is re-flagged, a new MMSI must be assigned. A "maritime object" could be anything that requests an MMSI identifier.—e.g., a vessel, fixed offshore installation, mobile unit, maritime aircraft, coast station, etc. Communications may be routed to "individual objects" or to "groups of objects". A group call to objects can be based on an object's locale, owner/operator/fleet, type, etc. or combinations thereof. MMSI are formed in such a way that the identity or part thereof can be used by telephone and telex subscribers connected to the general telecommunications network ...

Electron (rocket)
Electron is a two-stage, partially reusable orbital launch vehicle developed by Rocket Lab, an American aerospace company with a wholly owned New Zealand subsidiary. Servicing the commercial small satellite launch market, it is the third most launched small-lift launch vehicle in history. Its Rutherford engines are the first electric-pump-fed engine to power an orbital-class rocket. Electron is often flown with a kickstage or Rocket Lab's Photon spacecraft. Although the rocket was designed to be expendable, Rocket Lab has recovered the first stage twice and is working towards the capability of reusing the booster. The Flight 26 (F26) booster has featured the first helicopter catch recovery attempt. Rocket Lab has, however, abandoned the idea of catching Electron. In December 2016, Electron completed flight qualification. The first rocket was launched on 25 May 2017, reaching space but not achieving orbit due to a glitch in communication equipment on the ground. During its s ...

True Range Multilateration
True-range multilateration (also termed range-range multilateration and spherical multilateration) is a method to determine the location of a movable vehicle or stationary point in space using multiple ranges (distances) between the vehicle/point and multiple spatially-separated known locations (often termed "stations"). ''Accuracy limitations of range-range (spherical) multilateration systems'' Harry B. Lee, Massachusetts Institute of Technology, Lincoln Laboratory, Report Number: DOT/TSC-RA-3-8-(1) (Technical note 1973-43), Oct. 11, 1973 Energy waves may be involved in determining range, but are not required. True-range multilateration is both a mathematical topic and an applied technique used in several fields. A practical application involving a fixed loca ...

Software-Defined Radio
Software-defined radio (SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators/ demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system. A basic SDR system may consist of a computer equipped with a sound card, or other analog-to-digital converter, preceded by some form of RF front end. Significant amounts of signal processing are handed over to the general-purpose processor, rather than being done in special-purpose hardware (electronic circuits). Such a design produces a radio which can receive and transmit widely different radio protocols (sometimes referred to as waveforms) based solely on the software used. Software radios have significant utility for the military and cell phone services, both of which must serve a wide variety of changing radio protocols in real time. In the long term, software-defined radios a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indo-Pacific
The Indo-Pacific is a vast biogeographic region of Earth. In a narrow sense, sometimes known as the Indo-West Pacific or Indo-Pacific Asia, it comprises the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the seas connecting the two. The term is especially useful in marine biology, ichthyology, and similar fields, since many marine habitats are continuously connected from Madagascar to Japan and Oceania, and a number of species occur over that range, but are not found in the Atlantic Ocean. As a distinct marine realm, the region has an exceptionally high species richness, with the world's highest species richness being found in at its heart in the Coral Triangle, and a remarkable gradient of decreasing species richness radiating outward in all directions. The region includes over 3,000 species of fish, compared with around 1,200 in the next richest marine region, the Western Atlantic, and around 500 species of reef building corals, compar ...

Maritime Domain Awareness
Maritime domain awareness (MDA) is defined by the International Maritime Organization as the effective understanding of anything associated with the maritime domain that could impact the security, safety, economy, or environment. MDA is said to work as a ‘key enabler’ for other maritime security issues, such as anti-piracy patrols, in the way that in order to do effective patrols you need to have the ability of conducting effective MDA. The maritime domain is defined as all areas and things of, on, under, relating to, adjacent to, or bordering on a sea, ocean, or other navigable waterway, including all maritime-related activities, infrastructure, people, cargo, and vessels and other conveyances. Countries have always gathered information about the maritime environment, in order to generate intelligence necessary for various missions or finding enemy navies. Modern MDA however, was defined in the aftermath of the 9/11 terror attack and the terror attack on the destroyer USS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foreign Military Sales
Foreign Military Sales (FMS) is a security assistance program of the United States government to facilitate the purchase of U.S. arms, defense equipment, design and construction services, and military training to foreign governments. FMS is a government-to-government program where the United States Department of Defense through the Defense Security Cooperation Agency (DSCA) acquires defense articles on behalf of the foreign governments, protecting them from contract risks in negotiating with the arms industry and providing the contract benefits and protections that apply to U.S. military acquisitions. The FMS program was established through the 1976 Arms Export Control Act (AECA) and is overseen by the United States Department of State and the United States Congress through the annual Foreign Operations Appropriations Acts and National Defense Authorization Acts. The DSCA describes FMS as "a fundamental tool of U.S. foreign policy." FMS was the primary channel for U.S. arms e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
