PY0951 ACCURACIES - Complete network and local accuracy information.
PY0951 CBN - This is a Cooperative Base Network Control Station.
PY0951 DESIGNATION - HULL
PY0951 PID - PY0951
PY0951
PY0951 Horiz and Ellip are the horizontal and ellipsoid height accuracies
PY0951 at the 95% confidence level per Federal Geographic Data Committee
PY0951 Geospatial Positioning Accuracy Standards. SD_N, SD_E and SD_h are
PY0951 the standard deviations (one sigma) of the coordinates (NETWORK) or
PY0951 of the difference in the coordinates (LOCAL) in latitude, longitude
PY0951 and ellipsoid height. CorrNE is the (unitless) correlation
PY0951 coefficient between the latitude and longitude components of either
PY0951 the coordinate (NETWORK) or coordinate difference (LOCAL). Dist is
PY0951 the three-dimensional straight-line slope distance, in km, between
PY0951 station PY0951 and the corresponding local station. Local stations
PY0951 are stations processed simultaneously in a session regardless of
PY0951 distance.
PY0951
PY0951 Accuracy and standard deviation values are given in cm.
