其次，格洛纳斯系统卫星可以使用不同的频率，它的抗干扰能力是只能使用一种频率的GPS系统的三倍。

Secondly, the satellite deal to be able to use different frequencies, it is anti-jamming capabilities and can only use a frequency of the GPS system three times.

模拟分析结果表明，主动式具有较好的抗干扰性、较小的频率再用距离等优点。

It is shown from the data analysis that the active model has better anti-interference and less frequency reuse distance than those of the passive model.

频率捷变是主要的抗干扰措施，并能改善雷达性能。

Frequency agility is a main antijamming means and improves radar capability.
