Name

Subroutine UM535 - geocentric to geodetic transformation

Synopsis

      RECORD /zgeo/ mgeo
      RECORD /zgeo/ mgde 
        
      CALL UM535 (mgeo, mgde )

Arguments

mgeo

Geocentric location [in]

mgde

Geodetic location [out]

Description

The subroutine UM535 transforms geocentric coordinates into geodetic coordinates in function of the geoid parameters stored in common block UC160 (see Astron.J. 66, 15 [1961]). Note that both locations are specified in spherical coordinates. For the geodetic coordinates, the RADIUS refers to the geodetic altitude incremented by a mean Earth's radius (see /zgeo/).

When cartesian coordinates or other coordinates systems (GEI, SM, GSM, MAG) have to be used, the coordinate transformations can be realized with the help of subroutines UT541, UT546, UT550 and UT555.
