Software Defined Radio (SDR) is an emerging wireless technology which allows an electronic device equipped with a radio chip to be remotely reconfigurable to perform new functions via software downloads. With SDR, instead of having an expensive multifunction device, your cheap cellphone would automatically morph into a camera or an MP3 player. NASA wants to use this technology to reconfigure its satellites on the fly to perform new tasks. And its engineers have already built an SDR testbed allowing the quick development of new navigation algorithms. These new communication scheme could be used within 3 to 5 years in SDR-enabled space missions.
