ipTronix and Nextant have been collaborating on an indoor positioning system based on GPS signal regeneration. IpTronix contribution to the project, partially funded by Italian Space Agency (ASI), has been the development and manufacturing of a low cost GPS signal synthesizer that synchronizes with signal broadcast by satellites and reproduces it indoors simulating proper position in a given area. This cell based system allows discrete positioning in indoor applications using standard GPS receivers such as cell phones.
