XML Schemas for Assisted GNSS-SDR
GNSS-SDR can read assistance data from Extensible Markup Language (XML) files for faster Time-To-First-Fix, 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) 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 - GPS NAV message ephemeris parameters.
- iono_model.xsd - GPS NAV message ionospheric model parameters.
- utc_model.xsd - GPS NAV message UTC model parameters.
- gps_almanac_map.xsd - GPS NAV message almanac.
GPS L2C and L5
- cnav_ephemeris_map.xsd - GPS CNAV message ephemeris parameters.
- cnav_utc_model.xsd - GPS CNAV message UTC model parameters.
Galileo
- gal_ephemeris_map.xsd - Galileo ephemeris parameters.
- gal_iono_model.xsd - Galileo ionospheric model parameters.
- gal_utc_model.xsd - Galileo UTC model parameters.
- gal_almanac_map.xsd - Galileo almanac.
Please check https://gnss-sdr.org/docs/sp-blocks/global-parameters/ for more information about the usage of XML files in GNSS-SDR.
You could find useful the utility program rinex2assist for the generation of compatible XML files from recent, publicly available RINEX navigation data files.
