Topocentric Frame kernel for the ESA ground stations ==================================================== Creation date: 2011 March 8th Created by: J. Vazquez (ESA/ESAC) This is a frame kernel defining a topocentric reference frame for the ESA ESA ground stations. Location data used to define this frame are taken from the ESA web pages. The topocentric frame defines the z axis as the normal outward at the station site, the x axis points at local north (geographic) with the y axis completing the right handed frame. Positive azimuth is measured counter clockwise from the x axis. The equatorial radius and flattening factor for the ITRF93 reference ellipsoid are radius = 6378.1363 flattening = 1.0/298.257 Please note that all rotations mean the rotation of the coordinate frames about an axis and not of the vectors. The rotation defined in this file transforms vectors from the topocentric frame defined as z - normal to the surface at the site x - local north y - local west to an earth-fixed frame defined as x - along the line of zero longitude intersecting the equator z - along the spin axis y - completing the right hand coordinate frame This is a 3-2-3 rotation with angles defined as the negative of the site longitude, the negative of the site colatitude, 180 degrees. This file uses the reference frame alias EARTH_FIXED. In order to use this file in a SPICE-based program, the alias must be mapped to the frames ITRF93 or IAU_EARTH by a text kernel. An example of the text kernel assignments mapping EARTH_FIXED to ITRF93 is: TKFRAME_EARTH_FIXED_RELATIVE = 'ITRF93' TKFRAME_EARTH_FIXED_SPEC = 'MATRIX' TKFRAME_EARTH_FIXED_MATRIX = ( 1 0 0 0 1 0 0 0 1 ) These assignments must be preceded by the \begindata marker alone on a line. See the Frames Required Reading for details. The ITRF93 frame should be used for high-accuracy work. A binary high-precision earth PCK file should be used to convert the station location from terrestrial to inertial coordinates. Disclaimer: ---------- Please note that the accuracy of these coordinates might not be sufficient for the purposes of your application. A new definitive version, with more accurate information, shall be provided in the future. High precision information for the New Norcia ground station exists and is available in NEW_NORCIA_TOPO.TF, that shall be used along with NEW_NORCIA.BSP. Also note that the NAIF ID are provisional and they might change in the definitive version. Data for the ground stations topocentric frames follow. \begindata NAIF_BODY_CODE += ( 399500 ) NAIF_BODY_NAME += ( 'KIRUNA' ) FRAME_KIRUNA_TOPO = 1399500 FRAME_1399500_NAME = 'KIRUNA_TOPO'
