Abstract:

The use of commercial communications satellites for precise time transfer has been performed with a variety of techniques for a number of years. Military communications systems can also provide this function in a few deployed systems. This paper will describe a new design of a time transfer modem that can be produced 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. Compatibility with existing equipment, such as the HARTL Modem, is a goal of this development. The design and operating modes of this equipment will be described.
