RAPCAP: An Optical Communications Helmet.

Abstract

The RAPCAP underway replenishment communications system is designed to provide rig team-to-rig team voice communication between ships during underway replenishment (UNREP). The system employs a helmet-mounted optical transceiver that operates in the near infrared. Good-quality voice communications have been achieved beyond typical UNREP intership ranges of 75 metres. Because of its short range, RAPCAP is covert and can be used during emission control (EMCON) conditions. The system will reduce manpower requirements, enhance safety, and reduce time on station during the close-in coordinated maneuvers associated with at-sea replenishment operations. (Author)
