A single satellite signal.

[israel]

Hello.

Is there a way to receive a signal from a specific one GPS satellite and display it on an oscilloscope? what is the duration in nanoseconds of a typical signal?

Thanks.

I think the short answer is no.

The L1 GPS carrier wave is at a frequency of 1.57542GHz, the C/A (Coarse Acquisition) code is modulated onto this carrier, It repeats every 1023 bits and modulates at a 1MHz rate, however all satelllites transmit their sentences on the same carrier frequency using a unique Pseudo Random Noise code, this is called Code Division Multiplexing, it effectively means that the data from all 24 GPS satellites are are superimposed onto one another

Thanks. Is there any way to display all those signals on a scope? How long (nanos) is each signal?
