10.3.7.97d<br />

UE positioning GANSS additional UTC models<br />

This element contains contains several se<strong>ts</strong> of parameters needed to relate GNSS system time to Universal Time<br />

Coordinate (UTC), as defined in [68, 69, 70, 71, 72, 73]. Only one parameter set can be included in one UE positioning<br />

GANSS additional UTC models and which set of parameters to include depends on the GANSS-ID and UE capabilities.<br />

The UTC time standard, UTC(k), is GNSS specific. E.g., if GANSS ID indicates QZSS, UE positioning GANSS<br />

additional UTC models contains a set of parameters needed to relate QZST to UTC(NICT). If GANSS ID indicates<br />

Modernized GPS, UE positioning GANSS additional UTC models contains a set of parameters needed to relate GPS<br />

system time to UTC(USNO). If GANSS ID indicates GLONASS, UE positioning GANSS additional UTC models<br />

contains a set of parameters needed to relate GLONASS system time to UTC(RU). If GANSS ID indicates SBAS, UE<br />

positioning GANSS additional UTC models contains a set of pameters needed to relate SBAS network time for the<br />

SBAS indicated by SBAS ID to the UTC standard defined by the UTC Standard ID. If GANSS ID indicates BDS, UE<br />

positioning GANSS additional UTC models contains a set of parameters needed to relate BDS system time to UTC<br />

(NTSC).<br />
