• Resumen

  • COST Action 251 (Improved Quality of Service in Ionospheric Telecommunication Systems Planning and Operation) has been a dynamic group of 122 participants from 46 organisations in 20 Nations working as a technical community towards a common goal. The main objectives were to collect additional quantities and types of ionospheric data, to generate procedures for prediction of ionospheric models over Europe and to promote their use, to extend the existing models to give system performance statistics and to develop a methodology for channel simu1ation. The major achievements include especially the production of databases of ionospheric measurements, the development of procedures for ionospheric and p1asmaspheric modelling, mapping and forecasting ,and models for users for overall performance prediction of systems in Europe. The results obtained in the frame of COST Action 251 during the period 1995-1999 are summarised with particular reference to their application for terrestrial and Earth-space ionospheric telecommunication systems planning and operation. Recommendations for future activities are presented
