摘要
全球卫星导航定位系统具有全球、全天时、全天候、高精度三维定位和ns级定时等特点,同时存在抗干扰能力较低的缺点。主要论述了全球卫星导航定位系统的抗电子干扰技术,并对美国全球定位系统(GPS)抗干扰能力指标算法作出修正。
The global satellite navigation and positioning systems have characteristics of all globe,all time,all weather,high-precision 3Dpositioning,and timing at nanosecond level,but have weak anti-jamming capability.The anti-jamming technologies of the global satellite navigation and positioning systems are discussed.The algorithm for correcting the anti-jamming capability indexes in the U.S.global positioning system（GPS）is modified.
