Multiple frequency range positioning signal processing

A positioning signal processing method comprising:

• receiving, wirelessly at an apparatus, a first positioning signal in a first frequency range;
• receiving, wirelessly at the apparatus, a second positioning signal in a second frequency range;
• converting the first positioning signal by a first analog-to-digital converter (ADC) of the apparatus to produce a first digital signal at a first sampling rate that is based on a clock signal;
• converting the second positioning signal by a second ADC of the apparatus to produce a second digital signal at a second sampling rate that is based on the clock signal and that is different from, and related to, the first sampling rate;
• and
• adjusting at least one of the first digital signal and the second digital signal to provide synchronized digital signals.

An apparatus comprising:

• means for receiving, wirelessly, a first positioning signal in a first frequency range;
• means for receiving, wirelessly, a second positioning signal in a second frequency range;
• means for converting the first positioning signal by a first analog-to-digital converter (ADC) of the apparatus to produce a first digital signal at a first sampling rate that is based on a clock signal;
• means for converting the second positioning signal by a second ADC of the apparatus to produce a second digital signal at a second sampling rate that is based on the clock signal and that is different from, and related to, the first sampling rate;
• and
• means for adjusting at least one of the first digital signal and the second digital signal to provide synchronized digital signals.
