Abstract: GNSS-R interferometric reflectometry (also known as GNSS-IR, or GPS-IR for GPS signals) is a technique
that uses data from geodetic-quality GNSS instruments for sensing the near-field environment. In contrast to
positioning, atmospheric, and timing applications of GNSS, GNSS-IR uses signal to noise ratio (SNR) data.
Software is provided to translate GNSS files, map GNSS-IR reflection zones, calculate GNSS-IR Nyquist frequencies,
and estimate changes in the height of a reflecting surface from GNSS SNR data.
