gr-iridium-get_IQ_samples

This is a modified version of gr-iridium to extract IQ samples from the burst_downmix block for satellite authentication.

Features

• Uses bursts after the RRC filter (burst_rrc) in the burst_downmix block to extract IQ samples.
• Appends burst_rrc to the original burst stream.
• Passes the modified burst stream to the iridium_qpsk_demod block for demodulation.
• Successfully demodulated bursts are sent to the iridium_frame_printer block and exported to a file along with the demodulated bits.

Installation & Usage

To use this modified project, you need to:

1. Modify iridium_frame_printer_impl.cc in the lib directory.
2. Change the IQ file save path to your own directory.
3. Compile and run as per the official gr-iridium repository.

For more details, please refer to the official gr-iridium repository.
