G-III Reference Receiver States
The G-III Reference Receiver is in the
Off
state when power is removed from the receiver.
The
Boot
state is initiated by powering on the receiver or after the receiver accepts a reset command. After the
boot process is successfully completed, the receiver transitions without user intervention to the
Configuration
state.
The
Configuration
state allows the user to configure receiver settings such as those related to communications
and signal tracking. In
Configuration
state, the user can issue a command to field load the receiver software,
which causes the receiver to transition to
Maintenance
state.
After configuration is complete, a user issued command causes the receiver to transition to the
Operational
state which commences signal tracking and measurement processing operations. Channel assignments can only
be accomplished in the Operational state.
