Phone is not scanning any satalites #263

Open hosam37r opened 3 years ago

hosam37r commented 3 years ago

Hi All I create the *.bin file with running: ./gps-sdr-sim -b 8 -e brdc2710.20n -l 32.0244770,35.8971050,100 -s 1250000 -d 100

Then I transfer the file using: hackrf_transfer -t gpssim.bin -f 1575420000 -s 2600000 -x 0

I put the antenna and a galaxy s6 phone in a metal drawer to make sure it wont get any signals from outside. Also Wi-Fi and Bluetooth were off. I could not scan any satellites. The TX antenna LED on my HACKRF is solid red during transfer.

I read issues threads here. I tired with -C 10 and -C 4 but no luck

Can someone tell me what am i doing wrong?

Use the same sampling rate for both the signal generation and transmission.

Hi Thanks for the reply. I tried sampling both at 2600000 but still have the same problem. Thanks,
