Find out the intermediate frequency for GNSS applications

[bpshop]

What would you like to know?

Hi everybody, I am using the HackRF as front end together with gnss-sdr. Also, I tried to implement my own sdr gnss receiver, based on a file acquired with the HackRF one. In that context, I would need to now the intermediate frequency.

• The center frequency of the high frequency signal is 1575420000 Hz (1.57542 GHz) and
• the sampling rate is 2600000 Hz (2.6 MHz).

Given that, what is the center frequency of the IF signal?

Not being sufficiently familiar with electronical engineering to figure that out myself, I am thankful for any advice.

Actually, the intermediate frequency is relevant only if processing IF samples. Since the HackRF writes IQ samples, this information is not needed.
