Apple confirmed on May 16, 2015 that they have acquired the startup Coherent Navigation, which Dr. Humphreys co-founded in 2008 together with Clark Cohen (CEO at founding), Bill Bencze (VP of Engineering), Brent Ledvina (VP of Business Development), Mark Psiaki, and Mike Eglington. Dr. Humphreys left Coherent Navigation in 2009 to join the faculty of the University of Texas at Austin, but continued to collaborate as a private consultant and sub-contractor until the acquisition. Congratulations to the Coherent Navigation team for their hard work over the years — especially to Brent Ledvina and Bill Bencze, the two co-founders who shepherded the venture all the way through acquisition. Congratulations also to other key players: Paul Lego (CEO of Coherent Navigation at the time of acquisition), Isaac Miller (CTO of Coherent Navigation), and Rob Brumley (COO of Coherent Navigation). Never in recent memory has there been assembled such a concentration of position, navigation, and timing expertise in a single startup as in Coherent Navigation.
