Two-Way Satellite Time Transfer (TWSTT) Applications with the Eastern Range

Abstract

The Eastern Range at Cape Canaveral, as part of the Range Modernization program, is incorporating Two-Way Satellite Time Transfer (TWSTT) systems into their stations. A detailed study of the mechanization of TWSTT into their systems had been performed and an experiment into different satellite links has been reported before. A design implementation has been completed. Acceptance testing was successfully performed at the Naval Research Laboratory (NRL), including over-the-air testing prior to the first installation at the Range Operation Control Center (ROCC), Cape Canaveral. The first phase of ROCC installation was completed in July 1998. The results of acceptance testing at NRL indicated a sub-nanosecond time transfer capability. Data from those tests will be presented and discussed. Installion test data from the initial phase will be presented. Calibration of these units for absolute time comparison war difficult, but will support a nanosecond-level capability. The calibration methods and results will be described.
