Hi everything,
Is it possible to generate GPS signal in MATLAB? I know nothing about the signal structure of the GPS signal. Is there a GPS toolbox that can do this?
Once I get the IQ samples of the GPS signal, then I plan to actually transmit the signal over the air to a phone.
Thanks
Kevin

I think you guys are thinking too highly of me. I don't have the money nor ambition to put up a transmit antenna to transmit GPS signal (either to do good or bad to general public).

Hmm, I have not thought about the legal matter.
Yes, I want to spoof a GPS signal. What if I just do it in a basement and the tx power is very low and so it won't affect anyone outside the house. The tx power is so low that I don't think a phone in the ground floor will even get affected.

Hey Kevin,
Did you end up finding an answer for this? I'm not interested in doing an over-the-air experiment, but I'd be interested in simulating to first order a GPS signal.

No. No one posts an answer.
