Rinex Format
The Receiver-Independent Exchange (RINEX
1
) format is a broadly-accepted, receiver-independent
format for storing GPS data. It features a non-proprietary ASCII file format that can be used to
combine or process data generated by receivers made by different manufacturers.
The Convert4 utility can be used to produce RINEX files from NovAtel receiver data files.
Although RINEX is intended to be a receiver-independent format, there are many optional records
and fields. Please keep this in mind when combining NovAtel and non-NovAtel RINEX data.
When converting to RINEX, two files are produced - a RINEX observation file and a RINEX
navigation file. A third GLONASS file is produced if the data contains GLONASS observations. The
default names of these files conform to the RINEX Version 2.10 recommended naming convention of
ssssdddf.yyt, where:
ssss
4 character station name - Convert4 uses the first four characters of the <infile>
parameter as the station ID
ddd
day of year
f
file sequence number within the day - Convert4 sets this to zero
t
file type: o for the observation and n for the navigation file
Selecting the RINEX field, see Figure 11, Convert4 Screen Examples on Page 44, in the Convert4 To
section causes the:
1. Destination File: field to be replaced by the Observation File: and Ephemeris File: fields. Note
that Observation File refers to the RINEX OBS file while Ephemeris File refers to the RINEX
NAV file.
2. RINEX Headers buttons to appear allowing you to supply additional information that appears in
the header records of the RINEX output files (for example, Company Name, Marker Name and
Marker Number).
For best results, the NovAtel receiver input data file should contain the logs as in Table 5, NovAtel
Logs for Rinex Conversion on Page 46.
