This Master Thesis was conducted by Rikard Eriksson and Vlad Badea for their Master of Science degree in Electronics Design Engineering at the University of Linköping (Linköpings Universitet), Sweden. HTC Sweden AB initialized this Thesis and the Thesis contains a pre study of pseudolite based indoor navigation systems, a design of a simple pseudolite and finally some recommendations of applications.The pre study starts off with an introduction of the GPS system. This since pseudolite based systems and GPS have many similarities. Different pseudolites based techniques were then investigated and the pre study is wrapped up with a very short briefing on the Hammerhead chip.Some of the pseudolite based techniques were worth some more looking into and a pseudolite was therefore designed and simulated. There was unfortunate not enough time to actually build the pseudolite and verify it.Some recommendations to HTC Sweden were given in the last chapter of this the...
