WASHINGTON ��Dr. Jens Schroeder, managing director of RFmondial GmbH (DRM member), recently produced a report about the ongoing and successful project of Media Broadcast and the German Navy using DRM Datacasting to ships via HF. The project explored how to use DRM over shortwave for encrypted data transmission for maritime broadcasting of information and entertainment to ship crews at sea, according toDRM news

Digital shortwave via DRM can be an efficient and cost effective solution for the digital ship infrastructure. The transmission capabilities of digital point-to-multipoint broadcasting can provide data services to single ships as well as naval units worldwide.� A variety of maritime applications can be served, such as:

  • �� ��ECDIS maps
  • � � ��Weather data GRIB
  • � � ��Differential GPS via RTCM
  • � � Maritime Safety Information
  • � � ��NAVTEX / NAVDAT
  • � � ��SAFTEY-Net
  • � � ��Document management
  • � � ��Training material
  • � � ��News content

One of the next planned projects for RFmondial is working with the United States Coast Guard. The USCG is very interested in testing the propagation characteristics of using DRM with High Frequency as a means to broadcast digital data for its ongoing project in the Northwest Passage. If successful, the USCG will investigate using the system toenhance existing means of distributing digital maritime safety information in the far north of the U.S.
