GPS receiver/simulator using bladeRF

Post by christopharris »

Hi everyone,

I’m developing a GPS receiver/simulator using bladeRF. As far as I can see, the current firmware and fpga are improved with respect to packet losses.

At this moment, real-time GPS positioning using bladeRF worked well :P
Here is the demonstration video on YouTube.

However, there are still few packet losses if we set sampling rate as 40 Msps. The bladeRF is of course connected via USB 3.0 port. In addition, there is also a large DC bias.

Further, Tx at 1.5GHz doesn't work well. For example, I put following commands using bladeRF-cli.exe, but bladeRF-cli.exe has crashed after “tx start”.

Set frequency 1.57542G
Set samplerate 8M
rx config file=test.bin n=8M
rx start
tx config file=test.bin
tx start

Please let me know if anyone has any solutions.

Thank you.
