Scalar Characterization of Azimuthal Coverage Governing Geolocation Resolution

  • Nicholas Sharpitor (a1)
Abstract

We examine the relation between fix error and the azimuthal distribution of lines of position by subsuming the distribution into a scalar form Q analogous to the nematic order parameter of statistical physics. It is shown in the least-squares approach that the error behaves as (1−Q 2)−1/2. Simulation results are presented to demonstrate the control of Q as a strategy for fix improvement.
