Interesting topic, but the numbers mean little to me unless the reference coordinate system is given (or at least the program and the description of its purpose). If the satellite is controlled relative to the horizon they might be the pitch relative to the horizon and the yaw of pitch relative to the forward motion. For an astronomical satellite, the RA and Dec of the mirror's normal is appropriate. Also for a spinning but uncontrolled satellite, where the direction of the spin axis is to be computed ! söndag 23 december 2018 skrev José Luis Ruiz via Seesat-l < seesat-l_at_satobs.org>: > ...Values of the Mirrors: 58.4º 276.5º brightness -1.0 > 59.9º 248.3º brightness -0.5 > 52.3º 226.7º brightness +0.5 > 36.8º 215.5º brightness +1.5 > 35.61 215.2º brightness +2.5 > > -- -------------------------------------------------------- Björn Gimle, COSPAR 5919 59.2617 N, 18.6169 E, 51 m Satellite observation formats described: http://www.satobs.org/position/IODformat.html --------------------------------------------------------- _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-lReceived on Sun Dec 23 2018 - 09:12:37 UTC
