Hello~~
I have a few ca. 30h observations that were split in two rinex files (24h and 6h), so I'd like to merge them for processing.
I tried Ringo, but it only produced a 0 kb merged file (maybe the files were too big?). Any alternative you would recommend, possibly a freeware and user friendly? Of course I tried to AI suggestions, but wanted first hand human suggestions, too. I'm a Windows user unfamiliar with python etc.
Best regards ~~
The simplest solution would be to cut and paste with a text editor.
Open a RINEX file in a text editor and you will get a sense for the format. The first 20 or so lines are the header portion with metadata about the equipment, approximate position, starting time, etc. The remainder of the file is the raw GNSS observation data. Each block is identifiable by its observation epoch, i.e., unique timestamp.
To combine files, you could grab the lines of raw data from the second file and paste at the end of the first file.
As bene1 says, it is actually quite easy. Just make sure you use a text editor and not a word processor. There should be no extra bytes or characters in the file other than what was in the original files.
