A New Two-Way Time Transfer Modem

Abstract

The use of commercial communication satellites for precise time transfer has been performed with a variety of techniques for a number of years. Military communications can also provide this function in a few deployed systems. This paper will demonstrate a new design of a time transfer modem that can be produced at a reasonable cost and enable users to make direct comparisons with the Naval Observatory with nanosecond precision. A flexible all-digital design is being implemented that will enable a variety of different codes to be employed. The design and operating modes of this equipment are demonstrated.
