    These delayed signals cause measurement errors that are different for each type of GPS signal due to its dependency on the wavelength. [4] A variety of techniques, most notably narrow correlator spacing, have been developed to mitigate multipath errors. For long delay multipath, the receiver itself can recognize the wayward signal and discard it.

    For processes that produce homogeneous batches (e.g., chemical) where repeat measurements vary primarily because of measurement error; The "chart" actually consists of a pair of charts: one, the individuals chart, displays the individual measured values; the other, the moving range chart, displays the difference from one point to the next.

    The inertial system provides short term data, while the satellite system corrects accumulated errors of the inertial system. An inertial guidance system that will operate near the surface of the earth must incorporate Schuler tuning so that its platform will continue pointing towards the center of the Earth as a vehicle moves from place to place.

    en.wikipedia.org/wiki/Maximum_Elevation_Figure

    The MEF on Canadian VFR navigation charts is calculated by taking the higher value of: the top elevation of the highest obstacle plus the vertical accuracy (a variable number of feet) of the terrain source data; or; the elevation of the highest terrain plus 328 feet plus the vertical accuracy variable of the terrain source data.
