摘要: 研究了960 MHZ~1 610 MHz频段内GNSS系统之间以及其他业务和GNSS之间的兼容环境。以北斗卫星导航系统为例,利用抗干扰系数计算了GPS、GALILEO对北斗系统的干扰;其次,依据ITU规定的发射机频率容限和可允许的最大杂散发射或杂散域发射功率电平等约束条件,定义了其他业务对北斗系统的潜在干扰,创新性地利用潜在干扰率推演其他业务和北斗B1、B2、B33个频段业务的频谱兼容性;最后,初步给出了北斗系统在960 MHZ~1 610 MHz频段内的兼容分析结果。Abstract: The spectrum compatibility analysis among GNSS and that between GNSS and other operations are firstly advanced in this paper.The interference of GPS and GALILEO to BeiDou is calculated with interference coefficient in the beginning.Consequently,according to constraint conditions for transmitter frequency tolerances and maximum permitted power levels for spurious or spurious domain emissions set by ITU,the potential interference between other operations and GNSS is defined and is employed to obtain the interference between other operations and BeiDou B1,B2 and B3.Finally,spectrum compatibility of BeiDou in 960 MHz~1 610 MHz is given in the paper.The analysis method of spectrum compatibility proposed here hold for the spectrum compatibility of other operations.
