7.7.1 Satellites in SDGPS system

The SDGPS system consist of eight orbiting geostationary satel-
lites and is designed to form a seamless global augmentation system
consisting of Waas (USA), EGNOS (Europe) and MSAS (Japan). If
all three parts would become operative at the same time, there would
be no performance problem. However, since WAAS is the only
system currently in normal operation, the WAAS correction signals
can have a negative effect on receivers operating in Europe and Far
East outside the intended WAAS coverage area. In these areas, we
recommend that the 'SDGPS select mode' is changed from 'AUTO'
to 'PASSIVE'.
Refer to Addendum no. 183-0002-000 (included in the package) for
up-to-date information on the current status of the SDGPS system.
