On Top of the World: Lockheed Martin Corp. (NYSE: LMT), prime contractor for a group of satellites called MUOS, short for mobile user objective system, noted that the satellites offer reception at the poles — almost. The North Pole is 90 degrees north; the satellites reach latitudes of 89.5 degrees, roughly 30 miles away. Satellite reception at the top of the world is important because as polar ice melts, shipping will start taking northern routes, and people will go to the poles to start exploiting natural resources. People at the U.S. Navy’s Program Executive Office for Space Systems, part of Spawar headquarters in Old Town, work on the MUOS satellites. Lockheed Martin runs the program in Silicon Valley. MUOS satellites use WCDMA radio technology to offer smartphonelike communication capability. It’s a good fit for San Diego. This town is full of CDMA experts.
