We give some results of our analysis of the behaviour of the spacecraft EgyptSat in orbit in contingency mode as compared with free rotation parameters for other satellites. We propose a conception of an emergency situation with the object. It is shown that the integration of high-precision coordinate and photometric information obtained from different points allows one rapidly and efficiently to analyze the behaviour of spacecrafts which are in orbit without radio connection.
