Design of pseudolite supplemented geolocation system for universal receiver

Abstract

Global navigation satellite system (GNSS) has been widely used around the world, but problems like low signal intensity or signal been blocked could often cause the users unable to collect enough satellite signal for position purpose. A pseudolite geolocation system is designed which can worked instead of non-line-of-sight (NLOS) satellites, cooperate with on orbit GNSS satellites. We detailed a novel pseudolite system consists and working progress. Through application scenario analysis and simulation we verified that pseudorange errors is the main factor affect position accuracy, therefore, we provide pseudolite testing and correction methods. In addition, we also verified that pseudolite can significantly improve positioning accuracy in high buildings around urban environment.
