Description

The rinexinfo function returns the file information, including header contents, of a RINEX v3 or RINEX v4 navigation or observation file. rinexinfo supports RINEX files up to version 3.04 and version 4.02.

fileinfo = rinexinfo(filename) gets header information about the specified RINEX v3 or RINEX v4 file filename, and returns it as a structure, fileinfo. The contents of fileinfo depend on the RINEX file type and the satellite system in the file.
