Libraries included in plugins / Code taken from and in plugins

Elektro/Arktika, DecompWT, custom wavelet compression/decompression library originally used for MSG xRIT
GK-2A, libtomcrypt, for DES decryption
Inmarsat, libacars, for ACARS parsing
Inmarsat, mbelib, for AMBE audio decompression
Inmarsat, libaeroambe, not the library itself, but the code was adapted (for Ambe decoding)
Inmarsat, Scytale-C, for STD-C packet formats and parsing

Those libraries above are included directly as they are either header-only, not already present on most systems or required some modifications for the purpose of this software. For the code included, the licenses of each respective library applies.

Projects some code was taken from and included in libsatdump_core

GNU Radio, for the convolutional decoding / encoding (quite heavily modified) and a few other bits
gr-dvbs2rx, for TS Parsing and a few other bits
LeanDVB, for some definitions
SDR++, for the DSP stream implementation (thanks Ryzerth for the tip back then!) and a few other things, such as the SpyServer client

Libraries linked against

fftw3, used for all FFT operations
jemalloc, for memory allocation optimization on Linux and macOS
libpng, for PNG image loading/saving
nng, for network stuff
PortAudio, used for audio output for NOAA APT
Volk, to simplify SIMD utilization
zlib, required by libpng

SDR Libraries

UI Libraries

OpenGL ES and EGL, for OpenGL on Android
