A Novel Procedure for Assessing the Accuracy of Hyperbolic Multilateration Systems

This paper describes a novel procedure for determing the accuracy of hyperbolic multilateration systems. Basically, the procedure links the conventional accuracy measures (e. g., GDOP) to the moments and products of inertia of a mass configuration that is easily derived from the system geometry. Thus, the problem of determining accuracy measures is reduced to that of calculating simple moments and products of inertia. The insight provided by the procedure makes it possible to derive a variety of useful approximations for GDOP and other accuracy measures.
