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.

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.
