White Papers: Tech Brief Resiliency in PNT: GPS/GNSS Jamming and Spoofing Reliance on GNSS is now commonplace. However, all GNSS systems share a common vulnerability: their signals are very weak. GNSS satellites operate from Mid-Earth Orbit (MEO), approximately 20,000-25,000 km above the earth, to provide the best coverage and geometry for triangulation. As such, the transmitted signal is extremely weak upon arrival at the surface of the earth – so weak that it is weaker than the surrounding radio noise. Special signal processing techniques recover the GNSS signal from the background noise, but the weak signal strength at the user’s receivers makes GNSS navigation very susceptible to interference. pdf - 641 KB

Presentations and Articles: Testing GNSS Receivers to Harden Against Spoofing Attacks Spoofing is an attempt to deceive the GNSS/GPS receiver by broadcasting signals that the receiver will use instead of the live sky signals. This article describes a test system for spoofing allows testing the three major factors to consider in a spoofing attack, time synchronization to the signals to be spoofed, power level of the spoofing signal compared to the live sky signals, and accuracy of the position obtained by the spoofing signal to that of the actual position of the device being spoofed. Using a spoofing test system will allow a user to better understand the receiver and harden the system against spoofing attacks. pdf - 673 KB

Technical Notes and Briefs: Testing SAASM and Carrier Phase Receivers Orolia's GSG-6 GPS/GNSS simulators can be configured for dual frequency L1/L2 simulation. It generates both the C/A and P code signals simultaneously for the GPS and GLONASS navigation systems. Though it does not have an encryption capability to simulate a true classified P(Y) signal, it is still a powerful tool for acceptance testing of classified Selective Availability / Anti-Spoofing Module (SAASM) receivers. This technical note explains how to use the simulator for military SAASM receiver testing and for also testing commercial carrier phase receivers that use the L2 P(Y) signal. pdf - 148 KB

White Papers: The Advent of Tightly Synchronized Clocks in Distributed Systems The last decade has brought a paradigm shift in computing systems from single processor devices — whose performance plateaued — to distributed computing systems. In distributed systems, nodes execute concurrently with limited information about what the other nodes are executing at the moment. A key component of distributed coordination is the enforcement of consistent views at all nodes for the ordering of significant events. To this end, events are "timestamped" with logical counters or — increasingly lately — with tightly-synchronized physical time. White Paper

White Papers: The Importance of Low Phase Noise in Military Mobile Applications Military communications and intelligence-collection functions, traditionally associated with fixed sites and large platforms, are being pushed to tactical vehicles and sophisticated Unmanned Autonomous Vehicles (UAVs). This results in more C5ISR systems being installed on mobile platforms. Whether in the air, on land, or at sea, these vehicles will impart shocks and vibrations to their electronics, sometimes severely. In high vibration environments, the system designer must account for induced phase noise which can drastically affect overall performance. This white paper discusses the challenges of keeping low noise signals pure in any environment. pdf - 903 KB

White Papers: The Importance of Testing to Detect GNSS Vulnerabilities in Intelligent Transportation Systems

For more than a decade, GPS has been at the core of the navigation systems used in all types of road vehicles, train systems and marine transport vehicles. As industry moves from standalone navigation systems to the advanced multi-sensor systems used in intelligent transportation systems (ITS), GPS signals remain a key component of these systems.

The development of autonomous vehicles for road, rail and water demands a comprehensive and repeatable test plan for GNSS. This white paper discusses and outlines testing methods for GNSS performance and vulnerabilities.

White Papers: Time for Data Centers to Consider Time as a Service If you are in the data center business, you’re faced with a long list of customer demands as businesses and entire industries move operations to the cloud. But you’re also facing an increasingly competitive landscape where offering the best service and greatest value is paramount. Balancing what you can offer customers and at what cost can be complicated, to say the least. An often overlooked service offering, one which provides a large value to customers at a low cost to providers, is Time as a Service (TaaS). pdf - 472 KB

Technical Notes and Briefs: Time Synchronization for Secure Networks using Fiber Government and military networks often utilize the concept of unclassified (black) networks vs classified (red) networks to manage levels of information security. Since a complete “air-gap” around a highly sensitive network is not practical, every data connection is evaluated as a security risk. To synchronize a master source of time on a red network, Spectracom offers a fiber optical IRIG time code link between a SecureSync master-slave pair to offer high accuracy timing to a classified network while satisfying the requirements of SIPRNET, NIPRNET and other ultra-secure network systems. pdf - 254 KB

Application Notes: Time Synchronization's Role in Real-Time Trading GPS-enabled network time synchronization enables real-time trading of financial instruments by providing secure, accurate, and reliable time for events across the trading network. When an event occurs and is logged into the realtime database, the time associated with the event is accurate to national and international time standards. Synchronizing the time at which a transaction is executed from one system to another allows these systems to properly process transactions accurately. pdf - 106 KB

White Papers: Time Synchronization: Time is at the Heart of the MiFID Regulation

New regulations from MiFID II in Europe to the Consolidated Audit Trail in the US mandate that reportable events must be timestamped to much more accurate levels than ever before and that regulated organizations must have a clear understanding of time for all information they are required to report. Europe’s MiFID II, in particular — which came into force on January 3, 2018 — is far more prescriptive with regards to timestamping, as defined by the European Securities and Markets Authority (ESMA) within RTS 25.
