Concerning to the time shift investigation for INTMINS APRIL 99 operations schediule correction

The INTMINS April 1999 operations schedule was done on the base of the MIR ground track long-term prediction using the MIR's orbital elements status on 29/03/99.
The operations are planed for April 17-18 and 24-25.
The MIR's orbit disturbance after 29/03/99 introduces its contribution in the ground track position.
The difference between real ground track positions and one predicted 29/03/99 can be compensated by the some time shif. This time shift will be used for the operation schedule correction before its execution.
This home page concerns to the time shift investigation.
