a. Satellite Based Augmentation Systems (SBAS) include WAAS (North America), EGNOS (Europe) and MSAS (Japan).
b. Typical values. Performance specifications subject to GPS system characteristics, US DOD operational degradation,
ionospheric and tropospheric conditions, satellite geometry, baseline length, multipath effects and the presence of
intentional or unintentional interference sources.
Export licensing restricts operation to a maximum velocity of 515 metres per second.
c. Typical value. No almanac or ephemerides and no approximate position or time.
d. Typical value. Almanac and recent ephemerides saved and approximate time entered. For more information, refer to the
"SETAPPROXTIME" command in the
AG-Star User Manual Rev 4
