Application of Polynomial-Type Filters to Integrated Navigation Systems with Modular Architecture

The problem of methods application for decentralized processing of information in case of nonlinear polynomial algorithms implementation in individual measurement modules is considered. Recursive algorithms of polynomial filtering are proposed as an example of processing the calculated coordinates, inertial system readings, and measured distances to two responder beacons. The results of simulation of a centralized scheme of measurements processing and the scheme based on the federated filtering algorithms are presented.
