An anonymous reader writes: Apple is still sprinting to catch up with Google with its navigation software — the company just acquired Coherent Navigation, a startup focused on GPS tech. Its navigation services are reportedly more precise than most commercial-grade systems. Their system "combines signals from the traditional mid-earth orbit GPS satellites with those from the low-earth satellites of voice and data provider Iridium to offer greater accuracy and precision, higher signal integrity, and greater jam resistance." They've already worked with Boeing and the U.S. Department of Defense. Apple didn't disclose the terms of the deal or explain any specific plans for the GPS technology.
