Spectracom SecureSync User Manual

Note: For an effective jamming detection, and – to some extent – spoofing detec-
tion, a good antenna placement with optimal sky view resulting in a high signal-to-
noise ratio is essential. A strong signal is required to discern between normal sig-
nal fluctuations and a non-natural divergence of signal strength.
BroadShield Requirements
In order for BroadShield to work on your SecureSync system, the following requirements must
be met:
1.
The optional BroadShield software license needs to be enabled by applying the OPT-
BSH BroadShield license key. For more information, contact your local Spectracom Sales
Office. To determine if BroadShield has been activated on your SecureSync unit, nav-
igate to TOOLS: SYSTEM > Upgrade/Backup. The center panel System Configuration will
list the Options installed in your unit.
2.
BroadShield only works with a u-blox M8T receiver, not with Trimble receivers. To determ-
ine which receiver is installed in your unit, navigate to TOOLS: SYSTEM >
Upgrade/Backup. The center panel System Configuration will list the GNSS Receiver
installed in your unit.
3.
System Software 5.7.1 or higher must be installed in your unit. To determine which soft-
ware is installed in your unit, follow the instructions above and locate the System line
item in the System Configuration panel.
Activating the BroadShield License
If you have purchased the BroadShield license key and now want to activate it, please follow
the instructions under "Applying a License File" on page321.
To confirm that BroadShield has been activated on your SecureSync unit, navigate to TOOLS:
SYSTEM > Upgrade/Backup. The center panel System Configuration will list the Options installed
in your unit.
Enabling/Disabling the BroadShield Service
The Broadshield service can be run in two operating modes:
BroadShield only: In the event jamming or spoofing is detected, SecureSync will emit a
Major Alarm, however it will continue to consider the GNSS reference as valid, i.e. it
will NOT go out of sync.
Auto Sync Control: In the event jamming or spoofing is detected, SecureSync will emit a
Major Alarm AND it will go into Holdover mode.
To configure these settings:
