Aviation receivers manufactured to date rely solely on the L1 frequency (1575.42 MHz) being broadcast from the GPS satellites.The satellites also broadcast an L2 frequency (1227.60 MHz) which is primarily designed for use by the military.This second frequency is utilized by many non-military receivers in order to provide further mitigation of the ionospheric errors.However,the L2 frequency is not part of the internationally accepted spectrum for civil aviation nor is the signal designed for civilian use; therefore,it cannot be used for civilian navigation purposes.

目前制造的航空接收器都只依靠由GPS卫星广播发射的L1频率（1575.42 MHz）工作.卫星同时也广播发射只设计用于军事目的L2 频率(1227.60 MHz) .许多非军用接收机,出于进一步减轻电离层误差影响的目的,也使用这第二个频率工作.但 L2 频率既不属于国际认可的民用航空频谱的一部分,也不是设计用于民用的信号.因此,它是被禁止用于民用航空的.
