|RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1961
4.5 MI N FROM HOLTON. 4.45 MILES NORTH ON U.S. HIGHWAY 75 FROM THE JUNCTION OF U.S. HIGHWAY 75 AND STATE HIGHWAY 16 IN THE EAST EDGE OF HOLTON, THENCE EAST, ON MACADAM ROAD FOR 0.35 MILE TO THE SECURITY GATE OF THE MISSILE SITE. THE STATION IS ABOUT 250 FEET SOUTHEAST OF THE SECURITY GATE, CEMENTED IN A DRILL HOLE IN THE NORTH-CENTRAL EDGE OF THE CONCRETE ROOF OF THE MISSILE LAUNCHING RAMP.
- The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in October 1998.
- The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
- The Laplace correction was computed from DEFLEC99 derived deflections.
- The geoid height was determined by GEOID99.
- The dynamic height is computed by dividing the NAVD 88 geopotential number by the normal gravity value computed on the Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45 degrees latitude (g = 980.6199 gals.).
- The modeled gravity was interpolated from observed gravity values.
