The Application of NTP to Navy Platforms

Abstract

Navy platforms consist of many systems ranging from navigation and ship control to tactical analysis, sensors, and weapons. These systems, each composed possibly of multiple computing elements, are inherently time-dependent. In addition, modern surface ships are quickly adding additional COTS based computing elements and communication networks to address emerging requirements, Vital to making such a distributed system function in this environment is a stable robust time service. The Navy has been investigating various methods for the provision of a time service on shipboard platforms. This paper presents an overview of previous Navy efforts, a discussion of the metrics identified as applicable to the Navy environment, and a summary of the HiPer-D time synchronization subnet performance. In addition, this paper identifies ongoing and future work required to provide a stable robust time service in a shipboard environment.
