GNSS-SDR can read assistance data from
|
|
[Extensible Markup Language (XML)](https://www.w3.org/XML/) files for faster
|
|
[Time-To-First-Fix](https://gnss-sdr.org/design-forces/availability/#time-to-first-fix-ttff),
|
|
and can store navigation data decoded from GNSS signals in the same format. This
|
|
folder provides XML Schemas which describe those XML files structure.
|
|
|
|
[XSD (XML Schema Definition)](https://www.w3.org/XML/Schema) is a World Wide Web
|
|
Consortium (W3C) recommendation that specifies how to formally describe the
|
|
elements in an XML document.
|
|
|
|
## GPS L1 C/A
|
|
|
|
- [ephemeris_map.xsd](./ephemeris_map.xsd) - GPS NAV message ephemeris
|
|
parameters.
|
|
- [iono_model.xsd](./iono_model.xsd) - GPS NAV message ionospheric model
|
|
parameters.
|
|
- [utc_model.xsd](./utc_model.xsd) - GPS NAV message UTC model parameters.
|
|
- [gps_almanac_map.xsd](./gps_almanac_map.xsd) - GPS NAV message almanac.
|
|
|
|
## GPS L2C and L5
|
|
|
|
- [cnav_ephemeris_map.xsd](./cnav_ephemeris_map.xsd) - GPS CNAV message
|
|
ephemeris parameters.
|
|
- [cnav_utc_model.xsd](./cnav_utc_model.xsd) - GPS CNAV message UTC model
|
|
parameters.
|
|
|
|
## Galileo
|
|
|
|
- [gal_ephemeris_map.xsd](./gal_ephemeris_map.xsd) - Galileo ephemeris
|
|
parameters.
|
|
- [gal_iono_model.xsd](./gal_iono_model.xsd) - Galileo ionospheric model
|
|
parameters.
|
|
- [gal_utc_model.xsd](./gal_utc_model.xsd) - Galileo UTC model parameters.
|
|
- [gal_almanac_map.xsd](./gal_almanac_map.xsd) - Galileo almanac.

|
|
information about the usage of XML files in GNSS-SDR.

You could find useful the utility program
|
|
[rinex2assist](https://github.com/gnss-sdr/gnss-sdr/tree/next/src/utils/rinex2assist)
|
|
for the generation of compatible XML files from recent, publicly available RINEX
|
|
navigation data files.
