Transmit .bin file #147

Closed gasparjoao closed 6 years ago

gasparjoao commented 6 years ago

Hello I am doing a project for my masters degree and I am trying use this GPS signal simulator and a bladeRF. I'm trying to transmit the binary file exported by the simulator through the gnuradio FileSource block but I'm not getting location because it seems the signal comes with low power (i used the GPS test android app to see the satellites and power of signal). But if I transmit the same .bin file through the CLI of the bladeRF i can get location. Has anyone had a problem like this? And can you tell me what possible causes / solutions to solve this problem?

Thank you greetings

I'm not very familiar with GNURadio, but these sites seem to be helpful to solve your problem: https://github.com/Nuand/bladeRF/wiki/bladeRF-CLI-Tips-and-Tricks#GNU_Radio_Flowgraph http://sdrgps.blogspot.jp/2016/12/gps-fake-out-with-limesdr.html https://wiki.myriadrf.org/GPS_Simulation
