/* satellite positions and clocks ----------------------------------------------
* compute satellite positions, velocities and clocks
* args   : gtime_t teph     I   time to select ephemeris (gpst)
*          obsd_t *obs      I   observation data
*          int    n         I   number of observation data
*          nav_t  *nav      I   navigation data
*          int    ephopt    I   ephemeris option (EPHOPT_???)
*          double *rs       O   satellite positions and velocities (ecef)
*          double *dts      O   satellite clocks
*          double *var      O   sat position and clock error variances (m^2)
*          int    *svh      O   sat health flag (-1:correction not available)
* return : none
* notes  : rs [(0:2)+i*6]= obs[i] sat position {x,y,z} (m)
*          rs [(3:5)+i*6]= obs[i] sat velocity {vx,vy,vz} (m/s)
*          dts[(0:1)+i*2]= obs[i] sat clock {bias,drift} (s|s/s)
*          var[i]        = obs[i] sat position and clock error variance (m^2)
*          svh[i]        = obs[i] sat health flag
*          if no navigation data, set 0 to rs[], dts[], var[] and svh[]
*          satellite position and clock are values at signal transmission time
*          satellite position is referenced to antenna phase center
*          satellite clock does not include code bias correction (tgd or bgd)
*          any pseudorange and broadcast ephemeris are always needed to get
*          signal transmission time
