Jason Timmerman is a Principal Electrical Engineer with 20 years of experience in Rockwell Collins’ Advanced Technology Center. He is a U.S. patent holder with focused areas of research including computation and distribution of precision timing information, GPS-denied navigation, geo-location of RF emitters, multi-constellation GNSS architectures, integrated communication-navigation systems, software defined radios, multi-function radios, and advanced military communication data links. His current research includes a DARPA funded investigation of the use of advanced multi-function communication waveforms to achieve 10 picoseconds of timing accuracy in mobile platforms. Other recent research includes interference mitigation methods for GNSS receivers and the design of a secure single-chip multi-constellation GNSS processing engine. Timmerman received his MSEE from Iowa State University in 2004 and his BSEE from the University of Wisconsin-Madison in 1997.
