  1. The goals of product life cycle management (PLM) are to reduce time to market, improve product quality, reduce prototyping costs, identify potential sales opportunities and revenue contributions, maintain and sustain operational serviceability, and reduce environmental impacts at end-of-life. To create successful new products the company must ...

  2. The joint precision approach and landing system ( JPALS) is a ship's system (CVN and LH type), all-weather landing system based on real-time differential correction of the Global Positioning System (GPS) signal, augmented with a local area correction message, and transmitted to the user via secure means.

    The coordinate origin of WGS 84 is meant to be located at the Earth's center of mass; the uncertainty is believed to be less than 2 cm. The WGS 84 meridian of zero longitude is the IERS Reference Meridian, 5.3 arc seconds or 102 metres (335 ft) east of the Greenwich meridian at the latitude of the Royal Observatory. The WGS 84 datum surface is an o...

    Efforts to supplement the various national surveying systems began in the 19th century with F.R. Helmert's famous book Mathematische und Physikalische Theorien der Physikalischen Geodäsie (Mathematical and Physical Theories of Physical Geodesy). Austria and Germany founded the Zentralbüro für die Internationale Erdmessung (Central Bureau of Interna...

    Improvements to the global system included the Astrogeoid of Irene Fischer and the astronautic Mercury datum. In January 1966, a World Geodetic System Committee composed of representatives from the United States Army, Navy and Air Force was charged with developing an improved WGS, needed to satisfy mapping, charting and geodetic requirements. Addit...

    After an extensive effort over a period of approximately three years, the Department of Defense World Geodetic System 1972 was completed. Selected satellite, surface gravity and astrogeodetic data available through 1972 from both DoD and non-DoD sources were used in a Unified WGS Solution (a large scale least squaresadjustment). The results of the ...

    In the early 1980s, the need for a new world geodetic system was generally recognized by the geodetic community as well as within the US Department of Defense. WGS 72 no longer provided sufficient data, information, geographic coverage, or product accuracy for all then-current and anticipated applications. The means for producing a new WGS were ava...

    All components of WGS84 are regularly updated. The Department of Defense World Geodetic System 1984, Its Definition and Relationships With Local Geodetic Systems document, initially published in 1984, has been revised in 1997, in 2004 (as three editions of the TR8350.2), and finally in 2014 as the first edition of NGA.STND.0036.The regularly-update...

    PM C-RAM with the Phalanx CIWS

    A 20mm LPWS (Land-Based Phalanx Weapon System), a land based variant of the US's Phalanx close-in weapon system. PM C-RAM developed and successfully tested a system similar to Iron Dome.

    Iron Dome

    An Israeli missile system featuring multiple-target tracking and self-guided missile interceptors. Due to the ongoing increase of its engagement range and new missile and interception improvements, plus surface-to-air missile capability, it has developed into a fully-fledged air defence system. By November 2012, the system had intercepted over 400 rockets fired into Israel by Gaza Strip militants. Based on operational success, defense reporter Mark Thompsonestimates that Iron Dome is currentl...

    Nächstbereichschutzsystem MANTIS

    35mm fully automated C-RAM system, produced by Rheinmetall based on Oerlikon's Skyshield and ordered by the Luftwaffein use from 2011.

    Raytheonis developing a laser-based variation where low cost focused lasers will provide increased range and decreased time-to-intercept over the gun. A proof of concept was demonstrated on a 60 mm mortar round in 2006. Iron Beam is an air defense system in development by Israeli defense contractor Rafael Advanced Defense Systems. Unveiled at the 2...

  3. Decimal: 9 1 Binary : 0000 1001 0000 0001. In packed BCD, the same number would fit into a single byte: Decimal: 9 1 Binary: 1001 0001. Hence the numerical range for one unpacked BCD byte is zero through nine inclusive, whereas the range for one packed BCD byte is zero through ninety-nine inclusive. To represent numbers larger than the range of ...

  4. The AN/MPN-14K Mobile Ground Approach System can be configured as a complete Radar Approach Control (RAPCON) or Ground Controlled Approach (GCA) facility.The radar unit is used by air traffic controllers to identify, sequence, and separate participating aircraft, provide final approach guidance through air defense corridors and zones, and coordinate ID and intent with local air defense units ...

  5. Definition [ edit] The factorial number system is a mixed radix numeral system: the i -th digit from the right has base i, which means that the digit must be strictly less than i, and that (taking into account the bases of the less significant digits) its value to be multiplied by (i − 1)! (its place value). Radix. 8. 7.
