摘要： Methods of operating a satellite navigation system (SNS) receiver in a portable electronic device according to some embodiments include determining the presence or absence of a low frequency signal associated with power distribution lines, and disabling the SNS receiver in response to detecting the low frequency signal associated with power distribution lines. The methods may further include detecting weakening of a satellite navigation signal, and determining the presence or absence of a low frequency signal associated with power distribution lines may be performed in response to a detected weakening of the satellite navigation signal. Related devices are also disclosed.
摘要翻译： 根据一些实施例，在便携式电子设备中操作卫星导航系统（SNS）接收机的方法包括确定与配电线路相关联的低频信号的存在或不存在，以及响应于检测到低频信号而禁用SNS接收机 与配电线路相关联。 所述方法可以进一步包括检测卫星导航信号的弱化，并且可以响应于检测到的卫星导航信号的弱化来执行确定与功率分配线相关联的低频信号的存在或不存在。 还公开了相关设备。
