Abstract

This paper identifies the needs for space qualified frequency sources and presents two products manufactured by Tekelec Neuchatel Time SA (TNT) in this field. The first is a Rubidium Atomic Frequency Standard (RAFS) which is currently being developed for GNSS-2 program. This is a ultra-stable compact rubidium atomic clock based upon the magnetron technology also used in the Radioastron Rubidium Ultra-Stable Oscillator (RUSO). The second is the master oscillator (MO), designed for Long Duration Space Applications. It is a miniature, temperature stabilised, high-performance crystal oscillator. The MO was developed under GSTP program and one EQM MO successfully passed a space qualification. Flight models of this MO are now available
