在今年的巴黎航展上,俄制GPS干扰机引人注目,这种便携式干扰机据介绍能有效干扰美国的GPS和俄罗斯的模拟式制导系统GLONASS.这种GPS干扰机比较小(120mm×190mm×70mm),轻便(3kg),在两个GPS波段上(1227和1575MH_z)和两个GLONASS波段上(1250和1607MH_z)提供的干扰功率为8W.此干扰机既可以用高增益定向天线,也可以使用全向天线,据称如果干扰机与被干扰导航接收机处于直线位置上,其有效干扰距离达“几百公里”.展场上一个飞行员在介绍此干扰机时提醒人们特
At this year’s Paris Air Show, the Russian-made GPS jammer attracts attention, and the introduction of such a portable jammer effectively interferes with GPS in the United States and GLONASS, Russia’s analog guidance system. The GPS jammer is relatively small (120mm × 190mm × 70mm), light (3kg) and provides 8W of interference power on two GPS bands (1227 and 1575MH_z) and two GLONASS bands (1250 and 1607MH_z). This jammer can use either a high-gain directional antenna or An omnidirectional antenna can be used and it is said that if the jammer is in a straight line with the jammed navigation receiver, the effective jamming distance will be “several hundred kilometers.” A pilot at the fair reminds people when introducing this jammer
