# What is GNSSpy?
GNSSpy is a free and open source library for handling multi GNSS and different versions (2.X and 3.X) of RINEX files. It provides
Single Point Positioning (SPP) solutions by least squares adjustment using pseudo-range observations using precise ephemeris and clock files. GNSSpy can be used for editing (slicing, decimating, merging) and quality checking (multipath,ionospheric delay, SNR) for RINEX files. Ionospheric delay can be calculated from GNSS atmospheric models of IGS for single frequency RINEX data or removed using dual frequency RINEX data. It can be used for visualizing GNSS data such as skyplot, azimuth-elevation,time-elevation, ground track and band plots. Additionally, this library can be used for basic geodetic computations such as geodetic positions on reference ellipsoid and projection computations.
