ITU-R SM.1267 I RECOMMENDATION ITU-R SM. 1267 COLLECTION AND PUBLICATION OF MONITORING DATA TO ASSIST FREQUENCY ASSIGNMENT FOR GEOSTATIONARY SATELLITE SYSTEMS (Question ITU-R 32/1) (I 997) The ITU Radiocommunication Assembly, considering

2、 a) that several satellite monitoring earth stations exist in various parts of the world and are capable of collecting data relating to radiated emissions from geostationary satellites; b) that orbital slots for geostationary satellites are a valuable and scarce resource; c) that a knowledge of the

3、operational status of geostationary satellites recorded in the Master International Frequency Register is valuable to spectrum managers engaged in identifying orbital slots for new applicants; d) that Resolution 18 (Kyoto, 1994) solicits information regarding the reliability of the geostationary sat

4、ellite assignments recorded in the Master International Frequency Register and the role of international monitoring in this regard; e that a knowledge of the operational status of each geostationary satellite is of direct interest to participants of Radiocommunication Study Group 4, spectrum manager
