INTRODUCTION
-
The ITU-R Study Groups are established and assigned Study Questions by the Radiocommunications Assembly to prepare draft Recommendations for approval by ITU Member States. Additionally the Study Groups also conduct preparatory studies for World and Regional Radiocommunications Conferences. Work within these Study Groups is conducted in co-operation with other international organizations concerned with radiocommunications.
-
The structure of the Study Groups and the distribution of study questions and WRC preparatory activities between the Study Groups affects the number of meetings that aviation need to attend.
-
discussion
-
The ITU, in an effort to reduce it’s cost base has been reviewing it’s working methods and organisation. As a result of this review it has been decided that the study group structure within the ITU-R should be rationalised.
-
Study groups 1,3 & 7 as well as the Co-ordination Committee for Vocabulary, the Conference Preparatory Meeting and the Special Committee all remain unchanged. The only changes are to Study Groups 4, 6, 8 & 9. Study Group 6 (Broadcasting Services) was rationalised by reducing the number of Working Parties from 9 to 3. Study Groups 8 (Mobile, Radiodetermination, Amateur and related Satellite Services) and 9(Fixed Service) were both closed with the working being transferred to an expanded Study Group 4 (Satellite Services) and a new Study Group 5 (Terrestrial Services). The table below shows how the working parties within the old structure for Study Groups 4, 6, 8 & 9 map onto the new structure:-

Implications for Aviation
-
Aviation has traditionally been involved in Study Group 8 and Working Parties 8B and 8D. These Working Parties being within the same Study Group have meet at the same time in Geneva. From a logistical point of view this has had the advantage of minimising the number of trips, however there were problems in attending multiple overlapping meetings.
-
Under the new structure the work of Working Party 8B will now be under Working Party 5B and the work of Working Party 8B will now be under Working Party 4C. This has now split the work between two separate Study Groups and hence meetings will be held at different times. This has the advantage of allowing aviation delegates to attend both Working Parties without concern of overlapping meeting, however there will be a significant cost implication of having to attend 2 Working Parties from separate Study Groups.
