  2. Error analysis for the Global Positioning System - Wikipedia

    en.wikipedia.org/wiki/Error_analysis_for_the...

    This was intended to deny an enemy the use of civilian GPS receivers for precision weapon guidance. SA errors are actually pseudorandom, generated by a cryptographic algorithm from a classified seed key available only to authorized users (the U.S. military, its allies and a few other users, mostly government) with a special military GPS ...

  3. Dilution of precision (navigation) - Wikipedia

    en.wikipedia.org/wiki/Dilution_of_precision...

    Due to the relative geometry of any given satellite to a receiver, the precision in the pseudorange of the satellite translates to a corresponding component in each of the four dimensions of position measured by the receiver (i.e., , , , and ). The precision of multiple satellites in view of a receiver combine according to the relative position ...

  4. Sight reduction - Wikipedia

    en.wikipedia.org/wiki/Sight_reduction

    Sight is defined as the observation of the altitude, and sometimes also the azimuth, of a celestial body for a line of position; or the data obtained by such observation. [1] The mathematical basis of sight reduction is the circle of equal altitude. The calculation can be done by computer, or by hand via tabular methods and longhand methods.

  5. List of forms of government - Wikipedia

    en.wikipedia.org/wiki/List_of_forms_of_government

    Rule by a government based on consensus democracy. Military junta: Rule by a committee of military leaders. Nomocracy: Rule by a government under the sovereignty of rational laws and civic right as opposed to one under theocratic systems of government. In a nomocracy, ultimate and final authority (sovereignty) exists in the law. Cyberocracy

  6. Intercept method - Wikipedia

    en.wikipedia.org/wiki/Intercept_method

    Navigators use the memory aid "computed greater away" to determine whether the observer is farther from the body's geographic position (measure intercept from Hc away from the azimuth). If the Hc is less than Ho, then the observer is closer to the body's geographic position, and intercept is measured from the AP toward the azimuth direction.

    CEPS may refer to: Centre for European Policy Studies , a think tank based in Belgium Central Europe Pipeline System , a NATO system delivering fuel around Europe

  8. Precision engineering - Wikipedia

    en.wikipedia.org/wiki/Precision_engineering

    Precision engineering is a subdiscipline of electrical engineering, software engineering, electronics engineering, mechanical engineering, and optical engineering concerned with designing machines, fixtures, and other structures that have exceptionally low tolerances, are repeatable, and are stable over time.

  9. Conventional Prompt Strike - Wikipedia

    en.wikipedia.org/wiki/Conventional_Prompt_Strike

    Conventional Prompt Strike (CPS), formerly called Prompt Global Strike (PGS), is a United States military effort to develop a system that can deliver a precision-guided conventional weapon strike anywhere in the world within one hour, in a similar manner to a nuclear ICBM.
