Dr. Spilker serves as the Chairman of Rosum, was one of the original co-architects of GPS and was the previous founder and CEO of Stanford Telecom. Dr. Rabinowitz is Rosum's Chief Technology Officer and is a specialist in high-precision navigation systems. The Rosum team has demonstrated the unparalleled performance of the TV-based positioning system and established strategic partnerships with leading technology and service companies in the government and commercial wireless sectors. The recent investment gives the Rosum team resources to pursue multiple developments in the U.S. and Asia.
