Important Update
Information
The WAAS (Wide Area Augmentation System)
signal is currently transmitted by three geostationary satellites that
are completely independent of the GPS satellite system. Two of
these satellites (referred to as PRN 122 and PRN 134) are scheduled to
be decommissioned on July 31, 2007. Once those satellites cease
broadcasting correction signals, PRN 135 and PRN 138 (scheduled to be
operational July 11, 2007), will be the only active WAAS satellites.
Many GPS receivers will need to be updated to receive a configuration
change in order to continue receiving the WAAS correction signal.
