5.2.7.1 STL Option Module [1204-3E]
The Satelles Satellite Time and Location (STL) signal is broadcast on Iridium
satellites and offers a spoofing-resilient encrypted signal that is 1000x stronger
than GNSS- based timing signals. Hence, it is difficult to jam, and it can be
received indoors.
STL is a subscription-based service. Please contact Safran for details.
A SecureSync equipped with the STL 1204-3E option card can be operated with
or without GPS, depending on your application, i.e. STL can be utilized as a
backup, or as the only external timing source.
Note: Devices are shipped with the STL subscription deactivated. It is
necessary to contact customer service to activate the subscription:
stlsubscription@nav-timing.safrangroup.com US: +1 585 321 5800;

Hardware Installation
1. If your STL option card was purchased together with a SecureSync unit, the
card will be pre-installed in the unit. Proceed to Step 3.
2. If you purchased your STL option card separately, you will need to install
the card into the SecureSyncunit. For instructions, see the hard copy of the
Option Card Installation Guide that shipped with the unit, or see the Field
Installation instructions in the user manual.
Note: The -3E card can be installed in any free card slot.
3. Install the SecureSync unit in its assigned location e.g., in a server rack.
4. Install the supplied STL satellite antenna: The antenna is designed for
indoor use. The ideal location for the antenna is near the ceiling of the room
in which your SecureSync unit is located, or near an outside wall. In general,
a higher location is preferable over a lower location. Do not cover the
antenna with electronic equipment or other metal objects.
