Github Projects

iqtools - Collection of code for working with offline complex valued time series data (inphase and quadrature or IQ Data) with numpy written in Python. https://github.com/xaratustrah/iqtools

Project COGSWORTH - Creating images of RFI with a Raspberry Pi controled motorized dish receiver. https://github.com/FOULAB/Project-COGSWORTH

REDSAT - Raspberry Pi satellite SDR base station for weather & telemetry. Supports NOAA-15, NOAA-18, NOAA-19, METEOR-M 2, and MOVE-II https://github.com/StarGate01/redsat

Example code of Richard Lyons’ “Quadrature Signals: Complex but not complicated” paper https://github.com/daguiam/fft_quadrature_example

rtl_power_fftw - a program that obtains a power spectrum from RTL devices using the FFTW library to do FFT. It is inspired by the program rtl_power in librtlsdr. However, the said program has several deficiencies that limit its usage in demanding environments, such as radio astronomy. An inspection of rtl_power in hope of modifying it and obtaining better performance resulted in the conclusion that it would be an unfeasible task. https://github.com/AD-Vega/rtl-power-fftw
