Park, Hyuk; Camps, Adriano; Pascual, Daniel; Kang, Yujin; Onrubia, Raul; Onrubia, Raul
GEROS-SIM M2 Web is the simple implementation of M2 (Instrument to L1 module) of GEROS-SIM. It is a web-based software to compute Delay-Doppler Maps of GNSS Reflectometry in arbitrary configurations (friendly to the GEROS-ISS configuration.) The simulator has inputs via GUI: Receiver satellite height, sea surface height, elevation angle at specular point, sea surface wind speed / direction, total electron contents, and beam pointing errors. After the simulation, it produces outputs: DDM, central Doppler frequency, and the other auxiliary data. A user manual is provided, which contains the detailed description of input/output parameters, and how to execute the simulation.
