orbitdump: DUMP contents of ODF ORBIT file to stdout

• SYNOPSIS
  
      orbitdump [tstep=<value>] [offsett=true|false] >orbit.dat
  
• DESCRIPTION
  The tasks dumps the contents of the orbit file in the current ODF (pointed at via environment variable SAS_ODF) to stdout in the format t x y z d vx vy vz vabs where

  
  t 		 time in Mission-Elapsed-Time [s]
  
  x, y, z 		 components of S/C position vector in Earth-centeredJ2000 reference frame [km]
  
  d 		 norm of vector (x, y, z) [km]
  
  vx, vy, vz 		 components of S/C velocity vector in Earth-centeredJ2000 reference frame [km/s]
  
  vabs 		 norm of vector (vx, vy, vz)
  
  
  

  The time increment between successive elements is given via task parameter tstep which has a default value of 10s. offsett=true causes all time tags to be offset by the time of first element which, hence, is assigned $t=0$.
