Recent Progress in the NASA-Goddard Space Flight Center Atomic Hydrogen Standards Program

Victor S. Reinhardt

Abstract:	At NASA-Goddard Space Flight Center, and through associated contractors, a broad spectrum of work is being carried out to develop improved hydrogen maser frequency standards for field use, improved experimental hydrogen maser frequency standards, and improved frequency and time distribution and measurement systems for hydrogen maser use. The Applied Physics Laboratory of Johns Hopkins University under the technical direction of NASA-Goddard er has been developing a new generation of field operational hydrogen maser frequency standard called the NASA Research or NR hydrogen maser.
