摘要：	Digital Radio Mondiale (DRM) is a broadcasting technology that has the potential to disseminate electronic Maritime Safety Information over a wide geographical area. In this report, the Coast Guard Research and Development Center (RDC) presents a Concept of Operations (CONOPS) describing how a single DRM transmitter can provide coverage for the Arctic. The report outlines the methodology upon which the CONOPS is based including an Arctic field test conducted by the RDC in which user feedback and field test data were collected. The test proves that the HF DRM prototype offers an affordable and reliable alternative to distribute navigation safety information. Since the prototype infrastructure is comprised of the existing Coast Guard assets (e.g. USCG HF Transmitters and HF antennas) and proven Commercial-Off-The-Shelf products (e.g. DRM content server, modulator and receiver), the total cost of the prototype is relatively low. In addition, the report investigates how the coverage may be expanded to the contiguous Unites States and Hawaii. It concludes with specific recommendations for future work required to transition the technology to a public service to the mariner.
