适用范围
The CCIR considering a) that flexibility in the positioning of satellites can increase the efficiency of the geostationary orbit; b) that flexible satellite positioning can, in some circumstances, increase the Likelihood of successful frequency coordination; c) that repositioning can impact on the design of satellites as regards lifetime and the trade-off between coverage area and performance; d) that the repositioning of satellites will impact on earth segment operations and may require large numbers of non-tracking earth stations to be repointed; e) that the frequency of the repositioning should be limited so as to minimize disruption to the services being supported; f) that changing the order of satellites within a given arc of the geostationary-satellite orbit is Likely to be more onerous than changing their spacings by a smali amount; g) that the feasibility of accepting repositioning rather than some other means will depend upon the character of the affected earth and space stations; h) the analyses contained in Annexes 1 and 2.
