This output message indicates to the end-user that a new StarFire Almanac has been received
that is ready to be enabled / switched-over to.

The receiver is configured to regualarly receive and process a new StarFire Alamnac over-the-
air at the top of each hour. If the newly arrived StarFire Almanac contains a StarFire satellite
constellation or frequency change, the receiver outputs this message on active ports to inform
the user that a new StarFire Almanac has been received which is different than the current one
in-use.

In the event that the newly arrived StarFire Almanac is the same as the current one in-use, the
new almanac is discarded, and no message is output.
