Deterministic propagation prediction method developed by the European Broadcasting Union

A deterministic propagation prediction method was developed by the European Broadcasting Union (EBU) in order to provide a prediction model [1] which is acceptable to all parties concerned, and which has demonstrated accuracy and reliability. This method was also submitted to Working Party 3K of the International Telecommunication Union (ITU) as a deterministic path-specific prediction method [2]. Path general methods such as Recommendation ITU-R P.1546 [3] are good for general planning and coordination. They can be used with the minimum of information about the propagation path and can be agreed easily between countries. Averaged over a large number of transmission paths, such methods can be very accurate. However, as they take little account of terrain there can be significant prediction errors on individual paths. Thus, for detailed planning and coordination of specific transmitter locations there are considerable benefits in using `deterministic¿ prediction methods that take account of the terrain.
