卫星广播系统是按照国际电信联盟(ITU)规定的国际性技术标准构成的。能控制功率可变射束的下一代卫星广播系统也必须符合ITU标准。以现行卫星广播的12GHz频率为例,在对采用相同频率的别国广播系统和通信等其他业务规定了不致产生干扰的技术标准后,又有频道规划方案作依据,这就保障了各个国家进行卫星广播的权利。
Satellite broadcasting systems are constructed in accordance with international technical standards set by the International Telecommunication Union (ITU). Next-generation satellite broadcasting systems capable of controlling variable-power beams must also comply with ITU standards. Taking the 12 GHz frequency of the current satellite broadcasting as an example, after laying down the technical standards that will not cause any interference to other services using the same frequency in other countries’ broadcasting systems and communications, there will be another channel planning scheme which will ensure that all countries carry out Satellite radio rights.
