Rinex2assist
------------
This program reads data from RINEX navigation files and generates XML files that can be read by GNSS-SDR as Assisted GNSS data. The usage is as follows:
This program reads data from RINEX navigation files and generates XML files that can be read by GNSS-SDR as Assisted GNSS data.
### Building
This program is built along with GNSS-SDR if the options `ENABLE_UNIT_TESTING_EXTRA` or `ENABLE_SYSTEM_TESTING_EXTRA` are set to `ON` when calling CMake:
```
$ cmake -DENABLE_SYSTEM_TESTING_EXTRA=ON ..
$ make
$ sudo make intall
```
The last step is optional. Without it, you will get the executable at `../install/rinex2assist`.
The building requires two extra dependencies: the Boost Iostreams library and the program `uncompress`:
* The Boost Iostreams library can be installed through a package:
- In Debian / Ubuntu: `sudo apt-get install libboost-iostreams-dev`
- In Fedora / CentOS: `sudo yum install boost-iostreams`
- In OpenSUSE: `sudo zypper install libboost_iostreams-devel`
- In Arch Linux: included in `boost-libs` package.
- In MacOS: included in Macports / Homebrew `boost` package.
* The program `uncompress` is available by default in most UNIX and GNU/Linux systems.
- In Fedora / CentOS: `sudo yum install ncompress`
- In OpenSUSE: `sudo zypper install ncompress`
### Usage
The usage is as follows:
```
$ rinex2assist /path/to/RINEX_nav_file

The argument is mandatory (the name of the RINEX navigation file). The name `gps_ephemeris.xml` is given to the output if GPS NAV data is fould. If the RINEX file contains Galileo data, the corresponding `gal_ephemeris.xml` file will be generated. The program is also able to extract parameters of the UTC and the Ionospheric models from the RINEX header, if available. They will be called `gps_utc_model.xml`, `gps_iono.xml`, `gal_utc_model.xml` and `gal_iono.xml`.
There are some servers available for downloading RINEX navigation files. For instance:
