Dopplerfix

Simple program which fixes doppler shift on satellite signals
It uses libpredict as doppler shift calculator

Currently only supports 32bit floating point raw IQ files

Compile

• First install libpredict
• Compile
  • Shared linkage with libpredict:

    cargo build --release

  • Static linkage with libpredict:

    RUSTFLAGS="-C target-feature=+crt-static" cargo build --release --target x86_64-unknown-linux-gnu
