The aim of this project is to demonstrate the feasibility of providing automatic data and facsimile services for remote users via MF, HF and VHF radio systems. In this context, remote users are those who can only be reliably linked through long-range (HF or MF) radio systems, as they are located in remote areas away from national communications facilities or are travelling by land, sea or air.
Existing remote users employing MF and HF radio communications to access the public networks are mainly those using the maritime mobile service. The systems available are generally limited to the transmission of telephony, telegraphy and telex which, apart from telex, are operated manually, requiring operators at coast stations to connect calls to and from the public networks. Such users may alternatively employ mobile satellite communication systems (such as INMARSAT), which provide automatic access to numerous radio communications services including data and facsimile.
The project consists of four main areas:
The research has begun with an analysis of the state of the art and with a theoretical evaluation of the technological alternatives. The technological approach which demonstrates the best potential for accomplishing the objectives of the project will then be chosen. A feasibility model will demonstrate the results of the research in the four areas mentioned above.
An added objective is the development of a validation prototype of an HF data modem.
