In order to track a suborbital vehicle, some tracking system are used. Tracking radar can be used for this purpose. This paper presents a method using triangulation of antennas other than radars, for estimating the position of the vehicle. The goal is to improve the capability of keeping tracking the vehicle, even in loss of signal scenarios. Also, a dynamic filter is proposed for improving the estimation accuracy, based on a fuzzy system identification. Simulations were performed to demonstrate the proposed methods in estimating a suborbital vehicle position.

Purpose This paper aims to present a black-box fuzzy system identification method coupled with genetic algorithm optimization approach to predict the mixture thermal conductivity at dissimilar temperatures and nanoparticle concentrations, in the examined domains. Design/methodology/approach WO3 nanoparticles are dispersed in the deionized water to produce a homogeneous mixture at various nanoparticles mass fractions of 0.1, 0.5, 1.0 and 5.0 Wt.%. Findings The results depicted that the models not only have satisfactory precision, but also have acceptable accuracy in dealing with non-trained input values. Originality/value The transmission electron microscopy is applied to measure the mean diameters, shape and morphology of the dry nanoparticles. Moreover, the stability of nanoparticles inside the water is evaluated by using zeta potential and dynamic light scattering (DLS) tests. Then, the prepared nanofluid thermal conductivity is presented at different values of temperatures and concentrations.
