NOTE
Global SBAS Support
Wide area/regional satellite based augmentation
system (SBAS) support provided by the AeroNav
include WAAS (Continental US, Alaska, Canada and
most of Central America), EGNOS (most of Europe
and North Africa), MSAS (Japan) and GAGNAN
(India). These are regional augmentations of the
GPS satellite constellation and should not be
interpreted as meaning the AeroNav is compatible
with other GNSS constellation systems such as
Galileo (Europe), GLONASS (Russia), or Compass
(China).
The GPS navigation states possible are:
GPS Navigation State
Self Test
Init
Search
