Method for error budgeting of inertial navigation systems
Abstract
Error budgeting requires solving the problem of finding an allocation of allowable errors (error budget) among the subsystems such that the system meets a specified set of performance criteria. An approach for error budgeting of inertial navigation systems is proposed, in which the system performance statistics can be represented by the products of pairs of matrices, one of which containing the error budget and the other (a weighting matrix) characterizing the dynamics of the system applications. Using this approach, each iteration of the error budget requires in the order of n squared multiples, where n is the number of 'states' in the system error model. The weighting matrix can also characterize rms system performance for an ensemble of mission scenarios, which is particularly appropriate for tactical systems.
