The aim of this paper is to improve the scientific and methodological support of identification tasks when specifying the parameters of spacecraft motion. The article examines a systematic approach to ensuring the specification of the ballistic coefficient in the mathematical model of the spacecraft motion. For emergency situations, an approach was used that takes into account the object–system “task–solution tool”, which allows taking into account the errors of all elements of the navigation tool. The introduced structural property “generalized observability” makes it possible to solve the problem of Sb refinement in traditional and non-traditional conditions in the practice of operational navigation and ballistic support of spacecraft flight.
