N2 - Pseudolite is expected to be one of the best solutions for indoor positioning because of its compatibility with GPS and its positioning accuracy. However, since cycle slips frequently occur indoors and it is difficult to predict their occurrence, it is not so easy to retain a sufficient number of observation equations for position calculation. To avoid this problem, there are two possible methods; increasing transmitters, which is known as an effective way for outdoor GPS, and increasing receivers. In this paper, we evaluate the performance of these two methods for indoor positioning in terms of positioning success rate and positioning accuracy. The experiment we conducted shows that increasing the number of receivers is more effective than increasing the number of transmitters.
