RINEX data is made available at no charge from ORGN.
The nominal epoch rate for ORGN RINEX files is 5 seconds; however, users may request RINEX files with a faster epoch rate on a project-by-project basis, for example, an aerial photography project using airborne GNSS control. Contact ORGN Support in advance of your project if you have such a need.
The zipped RINEX files posted on the ORGN website contain both an observation RINEX file and a navigation RINEX file.
The file naming convention for the zipped file is: ssssdddh.rnx.zip, where “ssss” is used to identify the site name, “ddd” is the Julian day of the year, “h” is the hour identifier in UTC time (see chart below), “rnx” shows the type of files in the zipped file are RINEX, and "zip" is the type of compression used.
Do not be confused by the times listed on the left of the RINEX data page. They are the times that each file was posted onto the FTP server. The 8th character in the file name indicates the hour (UTC) that each hourly file was started, per the following chart:
For example, pdxa041p.rnx.zip is a zipped one hour RINEX file from station PDXA which contains data starting at 15:00 UTC on Julian Day 041 (February 10).
The Julian Day is the numerical day of the year starting with Julian Day 001 on January 1 and ending with Julian Day 365 on December 31 in a regular year (day 366 if a leap year). There are many interactive GNSS calendars available on the internet that give both the Julian Day and GPS week of a particular calendar date.
Each zipped RINEX file contains both an observation file and a navigation file from the site and a similar naming convention is used for both unzipped files: ssssdddh.yyt where “ssss” is used to identify the site name, “ddd” is the Julian day of the year, “h” is the hour identifier in UTC (see chart above), “yy” is the year, “t” is the file type (o= observation, n=navigation). For example, pdxa041p.07o is the observation file and pdxa041p.07n is the navigation file zipped into the above zipped RINEX file pdxa041p.rnx.zip.
