TX Performance Issue (GPS-related)

Hello bladeRF community, I currently have a bladeRF xA4 board.

I generated an IQ signal and this signal contains GPS satellite signals.
Using the exact same IQ.bin file with a USRP X310 series, GPS receivers can normally decode the GPS coordinates without any issues.

However, when I transmit this signal using the bladeRF xA4, but only a very small number of receivers are able to lock onto the GPS satellites.

What could be causing this issue?
