GMS Ground Monitor Station (MSAS)<br />
GMSK gaussian minimum shift keying<br />
Typically allows 8 kbps to be transmitted over a 12.5 kHz channel.<br />
GMSP Global Multimission Service Platform (USA)<br />
Could represent 8 satellites giving both higher-power GPS <strong>and</strong> comms.<br />
The 8 could replace the same number of current GPS sats at about the<br />
time of introduction of GPS III.<br />
GMT Greenwich Mean Time<br />
May be regarded as the general equivalent of UT1.<br />
GMU GPS-based monitoring unit<br />
US system for checking aircraft <strong>navigation</strong> performance.<br />
GN grid north<br />
Northerly direction indicated by the gyro-compass 000º index.<br />

GNE gross <strong>navigation</strong>al error<br />
GNS Ground Network System (US ATC)<br />
GNSS Global Navigation Satellite System<br />
Generic term for satellite <strong>navigation</strong> systems. GNSS-1 covers GPS <strong>and</strong><br />
GLONASS augmented with additional ranging, differential <strong>and</strong><br />
integrity signals (eg EGNOS, MSAS, WAAS). GNSS-2 should include<br />
Galileo & Compass. Covered by IMO Res. A.860(20) ‘Maritime Policy<br />
for the Future GNSS’.<br />
