Building a precise low cost indoor positioning and navigationwireless system is a challenging task. The accuracy and cost should be takentogether into account. Especially, when we need a system to be built in a harshenvironment. In recent years, several researches have been implemented tobuild different indoor positioning system (IPS) types for human movement usingwireless commercial sensors. The aim of this paper is to prove that it is notalways the case that having a larger number of anchor nodes will increase theaccuracy. Two and three anchor nodes of ultra-wide band with or without thecommercial devices (DW 1000) could be implemented in this work to find theLocalization of objects in different indoor positioning system, for which theresults showed that sometimes three anchor nodes are better than two and viceversa. It depends on how to install the anchor nodes in an appropriate scenariothat may allow utilizing a smaller number of anchors while maintaining therequired accuracy and cost.
