Title: Centimeter Accuracy Stand-alone Indoor Navigation System By Synchronized Pseudolite Constellation
Abstract: In recent days, navigation technology becomes more
important as location based service (LBS) such as E911
and telematics are considered as attractive business fields.
Commercial LBS requires that navigation system should
be inexpensive and available anytime and anywhere -
indoors and outdoors. If we consider these requirements,
it is out of question that GPS is the most favorite system in
the world. However, GPS has a serious problem. The
problem is that GPS does not operate indoors well. This is
because GPS satellites are about 20,000km above the
ground so that indoor signals are too weak to be tracked in
GPS receiver. This is what so called Indoor Navigation
Problem. To solve this problem, many researches have
been done around the world since 1990s. This paper is
also one of them and we will introduce an excellent
solution by use of synchronized pseudolite constellation.
