ABSTRACT:
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.
