### USING METHOD
|
||||||
|
Open the English version"KNZ_Convert_en_us_ver_1.2.5.exe", Click the "Single Convert", and
|
||||||
|
select the path of origin file. Click the button on the right of "Convert" button to choose
|
||||||
|
the origin format and target format. The converted file will generate in the same diectory
|
||||||
|
of origin file, if not select the path of output file. Click the "Batch Convert", same
|
||||||
|
as the operate of "Single Convert", it is to be noticed that the major version of files must
|
||||||
|
be same or the file of different version will fail to convert. The file name format of
|
||||||
|
converted is like: COV-{$originfilename}.{$originfileextensions}
|
||||||
|
|
||||||
|
### BRIEF
|
||||||
|
This software is developed by Python, mainly to complish the convert of different format
|
||||||
|
of RINEX observation data. At present, the convert between RINEX 2.xx and RINEX 3.xx is
|
||||||
|
already be basiclly supported.
|
||||||
|
|
||||||
|
Supported file format：
|
||||||
|
|
||||||
|
| FILE TYPE | MAJOR VERSION |2.10|2.11|2.12|3.00|3.01|3.02|3.03|3.04|3.20|3.30|4.00|4.01|

The double-character observation type of RINEX 2.xx will be matched by the list

|
|
||||||
|
Because of the observation type of RINEX 3.xx is not completely compatible with the type of
|
||||||
|
RINEX 2.xx. So, it will be omitted for the observation of same type from the same frequency.
|
||||||
|
In general, based on the rule: "Convert the first, omit the next." to compatible with the
|
||||||
|
RINEX 2.xx. At the same time, since this conversion is an irreversible processing method,
|
||||||
|
the converted observation file data can only be used as a reference when performing this
|
||||||
|
conversion, cannot replace the original version format.
|
||||||
|
|
||||||
|
Tip: if need to use RINEX file of strict format, you are supposed to be not use this software.
|
||||||
|
|
||||||
|
### UPDATE STAMP
|
||||||
|
2024/11/14: Currently, full support for RINEX 2.xx format conversion has been implemented, and
|
||||||
|
the format output errors of the previous version have been corrected. Currently,
|
||||||
|
support for converting RINEX 2.xx to RINEX 3.xx is available.
|
||||||
|
2024/11/15: Corrected output format, ignored RINEX 2.xx free signals and changed matching rules.
|
||||||
|
2024/11/17: Supports conversion between RINEX2.xx format and RINEX3.xx format, and also supports
|
||||||
|
conversion between the same major versions.
|
||||||
|
|
||||||
|
### UPDATE PLAN
|
||||||
|
1. ~~Short-term goals：Supports conversion of RINEX2.xx and RINEX3.xx observation files.~~ √
|
||||||
|
2. Middle-term goals：Supports conversion of RINEX2.xx and RINEX3.xx broadcast ephemeris files.
|
||||||
|
3. Middle-term goals：Gradually introduce support for conversion of RTCM format files.
|
||||||
|
4. Long-term goals：Receiver raw data conversion.
