This message is periodically used for the High Latitude StarFire Solution and is transmitted from
the GNSS receiver to the StarFire receiver. It can be set ONCHANGE and ONTIME for any
baud rate. However, the message will be output once every 10 seconds for both modes
regardless of the users rate specification.

The message will be used only if the STARFIRE-ONLY option is enabled on the unit. This
option will employ the time information to verify if the SF License is valid. The position will be
used to verify that the SF region is valid. Finally, it will calculate the lookup angle in order to
search for SF Satellites.

If the Starfire receiver does not receive this message within 15 minutes, it will default to output
corrections until the command is provided again. This message shall be encrypted to prevent
any changes to the time information and position.
