Impact of Used Communication Technology on the Navigation System for Hybrid Environment

Abstract EN

This paper deals with navigation of mobile device in outdoor and indoor environment by only navigation system or application.

In the paper, the navigation system is proposed in the light of seamless navigation service.

Main parts of the system from positioning point of view are based on GPS and WifiLOC system.

WifiLOC is an indoor positioning system based on Wi-Fi technology.

The proposal of the system will be described in detail.

The system is implemented at the University of Zilina as a pilot, noncommercial project; therefore it is called University Mobile Navigation System (UMNS).

The navigation system can be characterized as real-time system, that is, the system operations cannot be significantly delayed.

Since delay of the system depends significantly on communication platform used for map information downloading or communication with the localization server.

We decided to investigate an impact of the used communication platform on the time needs for some of the functions implemented in navigation system.

Measurements were performed in the real-world application.

Next experiment is focused on testing of the accuracy of used indoor positioning system.

Outdoor positioning accuracy is not tested because GPS is utilized in outdoor, and this system was already exhaustively investigated.
