3.1

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.
3.2

G-III Reference Receiver Modes

The G-III Reference Receiver has two modes: Normal and Failed. These modes are used to track the receiver
system health condition. If the receiver is determined to have failed as a result of IBIT or CBIT, the receiver
goes to Failed mode. Limited commands are accepted when the receiver is in Failed mode. When the receiver
is healthy, the receiver mode is set to Normal.
