Description

This Xcos block calculates jacobian of transformation of position and velocity vectors from one reference frame to another Available reference frames are: ECI, ECF, ITRS, TIRS, PEF, Veis, CIRS, TOD, TEME, GCRS, MOD, EME2000 and EOD. Detailed description of those reference frames can be found in CL_fr_convert help chapter. First two inputs accept 3x1 vectors of position and velocity. Third input with current simulation time in "modified julian day since 1950" needs to be always connected, because reference frame conversions rely on current time.

Data types

Dialog box

Input reference frame- reference frame of the input vetors

Output reference frame- reference frame of the output vetors

UTI-TREF- UTI-TREF [s] (1xN or 1x1)

TT-TREF- TT-TREF [s] (1xN or 1x1)

Position of the pole in ITRS- position of the pole [rad] (2xN or 2x1)

Correction to CIP coordinates- position of the pole [rad] (1x2)
