Global Positioning System - Error Sources and Analysis

Error Sources and Analysis

GPS error analysis which is found in Error analysis for the Global Positioning System is an important aspect for determining what errors and their magnitude are to be expected. GPS errors are affected by geometric dilution of precision and depend on signal arrival time errors, numerical errors, atmospherics effects, ephemeris errors, multipath errors and other effects. Variability in solar radiation pressure has an indirect effect on GPS accuracy due to its effect on ephemeris errors.

Famous quotes containing the words error, sources and/or analysis:

    Custom calls me to’t.
    What custom wills, in all things should we do’t,
    The dust on antique time would lie unswept,
    And mountainous error be too highly heaped
    For truth to o’erpeer.
    William Shakespeare (1564–1616)

    Even healthy families need outside sources of moral guidance to keep those tensions from imploding—and this means, among other things, a public philosophy of gender equality and concern for child welfare. When instead the larger culture aggrandizes wife beaters, degrades women or nods approvingly at child slappers, the family gets a little more dangerous for everyone, and so, inevitably, does the larger world.
    Barbara Ehrenreich (20th century)

    Whatever else American thinkers do, they psychologize, often brilliantly. The trouble is that psychology only takes us so far. The new interest in families has its merits, but it will have done us all a disservice if it turns us away from public issues to private matters. A vision of things that has no room for the inner life is bankrupt, but a psychology without social analysis or politics is both powerless and very lonely.
    Joseph Featherstone (20th century)
