An Evaluation of Optimization Algorithms for the Optimal Selection of GNSS Satellite Subsets

Remote Sensing
Continuous advancements in GNSS systems have led, apart from the broadly used GPS, to the development of other satellite systems (Galileo, BeiDou, GLONASS), which have significantly increased the number of available satellites for GNSS positioning ...

Analysis of the precision of determination of aircraft coordinates using EGNOS+SDCM solution

Archives of Transport, 2023
This paper presents an algorithm for determining the precision parameter for aircraft position coordinates based on a combined GPS/EGNOS and GPS/SDCM solution. The proposed algorithm uses a weighted average model that com-bines a single GPS/EGNOS and GPS/

Optimal Sensor Placement for Dilution of Precision Minimization Via Quadratically Constrained Fractional Programming

IEEE Transactions on Aerospace and Electronic Systems, 2019
An approach to find the global optimal solution of the dilution of precision (DOP) problem is presented. The DOP optimization problem considered assumes an environment comprising multiple randomly predeployed sensors (or navigation sources) and an ...
