This menu option allows you to disaable/enable Jamming or Spoofing. Spoofing refers to
impersonating the live-sky GNSS signal, thus "deceiving" the GNSSreceiver, while Jamming
refers to interference of the signal, i.e. making the live-sky GNSS signal unusable. Per default,
both are Enabled.
ABOUT
The About menu displays Version and Build Date of the BroadShield software. Periodic
updates are released with SecureSync system software updates, as they become available.
Monitoring BroadShield
You can use the BroadShield Web UI to monitor the jamming/spoofing status, or the
SecureSync Web UI. In the latter case, you will be informed of a Major Alarm, as described
below:
BroadShield Alarm
If BroadShield detects a jamming or spoofing event, SecureSync will emit a
BroadShield Crit-
ical, Major Alarm
(see illustration below). SecureSync will go into Holdover (yellow HOLD
status light) and – depending on the BroadShield Service setting (see "Enabling/Disabling the
BroadShield Service" on page175) and your SecureSync settings – will either remain in sync
(green SYNC status light), i.e. it will continue to output time and frequency signals considered
valid, or it will go out of sync (red SYNC light).
You can also configure a notification alarm, see "Enabling/Disabling the BroadShield Ser-
vice" on page175.
BroadShield Web UIMonitoring
The BroadShield Web UI will also display real time signal status information, or a map status.
