[Hackrf-dev] HOW to SPOOF OR Transfer Wrong GPS cordinates using HACKRF One.

[john vargh]

Hello ,

I am trying to spoof GPS device using Hackrf one.
Before that I have tried the some exercisw Like Receive FM & JAMMING the
GPS Device.
Antenna used is ANT500.

But I want to spoof the GPS Device for TESTING PURPOSE only.

Steps I followed is :-

1.:~/Downloads/gps-sdr-sim-master$ ./gps-sdr-sim -b 8 -e brdc3540.14n -l
46.257664,11.956105,100

2.Downloads/gps-sdr-sim-master$ hackrf_transfer -t gpssim.bin -f 1575420000
-s 2600000 -a 1 -x 0


Expected behaviour

Then my gps device must show this latitude & longitude. But it is not
working as expected.
Actual behaviour

Transmit LED is ON, but no spoofing happens on GPS device
