Attribute | Scope | Type
authenticationResult | Public | Boolean
definition=Report of the authentication function result as provided by a GNSS constellation (True = GNSS constellation is trusted) (see CWA 16390:2018 Table 9). order=0
numberOfSatellitesTracked | Public | NonNegativeInteger
definition=Number of tracked satellites from the constellation specified by the "gnssSystemId" attribute. order=1
Notes: | Number of satellites tracked from a given Constellation (even if not used in the Location Speed Time solution)<br/>
sbasCorrectionStatus | Public | Boolean
definition=Indicates if the identified constellation is SBAS-corrected (value = true) or not. order=2
Notes: | According to CWA 16390 Revision :<br/>Two possible values indicating:<br/><ul> <li>Identified constellation is not SBAS corrected</li></ul> or<br/><ul> <li>Identified constellation is SBAS corrected</li></ul> <br/>The Id of the constellation is given by the gnssSystemID<br/><br/>Other values could be possibly used in the future (e.g. they could be used in the case a future SBAS will augment other GNSS constellations). In this case a new attribute boolean will be added for each Augmented constellation.<br/><br/>
