An end-to-end performance simulator for GNSS-R space mission have developed including the whole range of observation conditions, and instrument and platform parameters, in order to better understand, analyze, and quantify the performance of this GNSS-R space mission. The simulator has a user-friendly interface for parameter input, and users can conveniently simulate and analyze the DDMs and waveforms in various observation scenarios. The current version of GEROS-SIM L1 is available on the web ( for public use.
