State Plane Coordinate System of 1983
www.ngs.noaa.govThe State Plane Coordinate System of 1927 was designed in the 1930s by the U.S. Coast and Geodetic Survey (predecessor of the National Ocean Service) to enable surveyors, mappers, and engineers to connect their land or engineering surveys to a common reference system, the North American Datum of 1927. The following

www.ngs.noaa.govFrom Fig. 1 it is clear that the azimuth c,' of the satellite is a function of the angle f3. In this particular situation, as can be seen in the Fig. 1, eL' = 180 ~ _ 13. The angle 13 is computed using Napier's rules as 13 = cos-l(cot "y tan +') (6) Consequently, once the vertex angle 13 at P' is known, the value of the ...
