Merge: allows to merge several RINEX files. Final RINEX file header will be updated by all the information (time start / stop, available GNSS, signals, data types) collected from merged files. Merged file may be also modified / converted (see options below for Edit). Merged files should be collected by the very same receiver.

Edit: allows to transform RINEX file from one version to another one (including converting Compact RINEX CRX Hatanaka). For instance, RINEX2 to RINEX4 or vice versa. Also one may modify RINEX file by removing GNSS, SVs, Signals, Data Types as well as do decimation (for instance, convert 1 sec file to 30 sec). "Edit" option allows to optimize RINEX file structure: keeping the same RINEX version, reduce size by optimizing satellites and signals slots, sort satellites in epoch, remove redundant spaces and empty slots / signals.

Convert RTCM3: allows to convert RTCM3 file (including MSM) into RINEX file.

Convert UBLOX: convert UBLOX UBX file into RINEX observation file. The log must contain UBX-RXM-RAWX message (Multi - GNSS raw measurements). Mostly focused on professional UBLOX F9 receivers. Epoch time stamps will be aligned and measurements will be corrected by receiver clock offset during converting.
