Abstract :
An evaluation of the identified options in performing differential navigation between spacecraft in rendezvous operation at low-earth orbits has been performed, including evaluation of the parameters of the corresponding algorithms. Within this evaluation many options have been considered, and the optimal solution has been identified. With this optimal solution a method for differential navigation has been selected that provides very accurate results even in the range of centimeters, while requiring low physical requirements of CPU time and memory
