Aerospace Instrument-Making Annotation << Back Algorithm for the Formation of Mathematical Models of a Promising Navigation Complex of an Aircraft Selezneva M.S., Neusypin K.A., Grigoriev L.V. The problem of forming mathematical models in algorithmic support of a promising navigation complex of an aircraft is considered. The self-organization method is used to construct the models. The ensemble of selection of models includes qualitative criteria of the degree of observability, controllability and parametric identifiability. Depending on the target purpose of the model, the corresponding composition of the ensemble of selection criteria is used, which allows obtaining models with the desired qualitative characteristics. Keywords: navigation system, aircraft, quality characteristics, mathematical model, accuracy improvement. DOI: 10.25791/aviakosmos.4.2025.1477 Pp. 50-58.
