Semenov (JPL/NAIF) Description ----------- These placeholder Korean Ground Station Network (KGSN) station location and topocentric frame orientation SPK and FK provide semi-realistic data for to-be-built KARI Deep Space Antenna (KDSA). They are intended to be used only in support of the KPLO SPICE hands-on programming lessons and must not be used for any other applications. In these kernels the KDSA position is assumed to be coincident with the large antenna dish on the west side of the Kumsan Satellite Service Center (117, Garaeul-gil, Geumseong-myeon, Geumsan-gun, Chungcheongnam-do, 32708, Korea). The geodetic longitude and latitude coordinates of that antenna obtained from https://www.google.com/maps on 2019-OCT-18 were: LON: 127.486661 deg LAT: 36.125384 deg The altitude of that antenna obtained from https://www.freemaptools.com/elevation-finder.htm on 2019-OCT-18 was ALT: 0.154 km These coordinates are arbitrarily assumed to be with respect to to IAU 2000 Earth ellipsoid (from pck00010.tpc): BODY399_RADII = ( 6378.1366 6378.1366 6356.7519 ) in the ITRF93 frame. The SPICE integer code for the KDSA station is 398001; the SPICE name is 'KDSA'. begindata NAIF_BODY_NAME += ( 'KDSA' ) NAIF_BODY_CODE += ( 398801 ) SITES = ( 'KDSA' ) KDSA_CENTER = 399 KDSA_FRAME = 'ITRF93' KDSA_IDCODE = 398801 KDSA_LATLON = ( 36.125384, 127.486661, 0.154 ) KDSA_UP = 'Z' KDSA_NORTH = 'X' KDSA_BOUNDS = ( @2000-JAN-1, @2050-JAN-1 ) begintext begintext [End of definitions file]
