The ARI was developed in 2015 by the Astrophysics Department of Pontificia Universidad Católica de Chile (PUC) and BlueShadows. ARI is an implementation of a 2-element radio interferometer using two units of STR (Small Radio Telescope) designed by the Haystack Observatory. Signal Hound spectrum analyser and ROACH are integrated into ARI as the backend of the system and allow the spectral analysis of the signals captured by the interferometer. The control integration of the ARI components is done using the ICE software framework for Remote Process Call, which allows for the interaction and coordination of independent modules of Hardware and Software. The local control of the radio telescopes is done through controllers implemented over Raspberry Pi platform. ARI is aimed for academic purposes, allowing the execution of experiments for learning the fundamentals of Radio Astronomy.
