- Abstract
- It has been established that one of the main directions of development of multi-satellite space systems is the transfer of part of the control functions from ground-based means to the onboard complex of the spacecraft, in particular, the implementation of ephemeris-time support in autonomous mode. The work systematized the approach to solving the problem of autonomous ephemeris-time support of spacecraft of a multi-satellite orbital constellation. The authors proposed an approach to real-time estimation of motion parameters and corrections to onboard time scales of spacecraft based on one of the methods of dynamic filtering - extended Kalman filter.
