UCMA (Universal Code Multipath Analyzer ) is a tool designed to analyze the code multipath observables MC1, MP1, MC2, MP2, MP5 in time and frequency domains. This tool requires the input data to be in Rinex 3.00 format. As its name implies, UCMA allows processing all currently available signals (L1, L2 and L5 signals) from all major navigation satellite systems ( GPS, GLN, WAAS, GIOVE )
