Engineers at the University of Texas at Austin have now developed a cheap GPS system. Using a $5 antenna and software they developed and a Samsung Galaxy phone they were able to map in 3D accuracy of two centimeters. The development team now has a startup, Radiosense LLC, to further evolve the technology. They are working with Samsung to develop a low cost snap-on system, which will contain the antenna and software-based receiver. They say that the receiver should eventually be for sale at less than $50.00.
