Modified librtlsdr (rtl_sdr command) to enable seamless switching of frequency during reception. This is based on the async_rearrangement branch of librtlsdr.
This lib enables TDOA localization with RTL-SDRs, when a reference transmitter is used for synchronization. More information: http://www.panoradio-sdr.de/tdoa-transmitter-localization-with-rtl-sdrs/
rtl_sdr -f <frequency 1> -h <frequency 2> -n <num_samples> <out_filename>
receives first <num_samples> IQ samples at <frequency 1> (in Hz), then <num_samples> IQ samples at <frequency 2>, then again <num_samples> at <frequency 1> without interruption. For help and more options type rtl_sdr.
Example Usage: rtl_sdr -f 200e6 -h 100e6 -n 1e3 record.dat receives first 1000 IQ samples at 200 MHz, then 1000 IQ samples at 100 MHz, then again 1000 at 200 MHz without interruption, resulting in 3000 samples in total.
- navigate to main folder librtlsdr-2freq/
- mkdir build
- cd build
- cmake ../
- make
binaries (rtl_sdr) can then be found in build/src/
