Case Study: Defense Network Upgrades and Precision Time Synchronization

April 30, 2019
By Jean-Arnold Chenilleau, Program Manager
 
Orolia was contacted by a global defense infrastructure client to evaluate the obsolescence of its fixed site timing infrastructure, and the impact on overall system performance. This legacy defense network was a large installation specifically designed to synchronize multiple clocks in shelters separated over a long distance of several kilometers. These private point-to-point links were at least thirty years old. A private phone network is an example of this type of infrastructure.

Cybersecurity Checklist for Secure Timing

January 31, 2019
By David Sohn, Senior Product Manager
 
Network cybersecurity is top of mind these days for both government agencies and commercial enterprise. As the heart of network synchronization, time and frequency systems should include a standard suite of security features that give network administrators confidence in the cybersecurity protocols of their time servers.

Navwar Threats: How to Protect Naval Operations

November 12, 2018
By Stéphane Chèze, Business Development Director, Government Systems
 
Navigation warfare (Navwar) is an ever-increasing threat to naval missions, some of the most complex, covert and remotely operated military missions in the world. The naval theater of operations today relies on access to secure, continuous and reliable Positioning, Navigation and Timing (PNT) data for critical situational awareness and C5ISR systems.

The Importance of Low Phase Noise in Mobile Applications

September 19, 2018
By John Fischer, VP, Advanced R&D
 
Whether in the air, on land, or at sea, 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.

Position, Navigation, and Timing: Assured, but Affordable?

September 10, 2018
By Jon Sinden, Product Manager, Mobile Mission Systems
 
Maintaining a state of military readiness is a top priority for defense agencies. The ideal approach would deliver a consistent solution that is cost-effective across different platforms, with the ability to provide a compatible, scalable system to all of them. Expensive, inflexible A-PNT solutions will not solve the total problem. To provide affordable A-PNT for every link in the communications chain, a different approach is needed.

Need Low Phase Noise Under Vibration?

August 29, 2018
By Scott Hildebrandt, Senior Program Manager
 
To improve performance of your radar system or signal intelligence (SIGINT) receiver, you need a time and frequency reference that can deliver a low phase noise signal. If your mission is signal intelligence gathering, then that means deeper penetration and more intelligence gathered.

Protecting GPS-Reliant Military Systems – Part 2

August 6, 2018
By John Fischer, VP, Advanced R&D
 
As is widely understood, GPS signals are weak and vulnerable to interference. Interference can be unintentional, such as side band energy from radio transmissions on the battlefield, or intentional. Intentional interference can be jamming or it can be a fake signal, sometimes called spoofing or sophisticated jamming. Spoofing is potentially the most dangerous type of interference. Connectivity and signal disruption is one issue; acting on misinformation or falsified data could be catastrophic.

Protecting GPS-Reliant Military Systems – Part 1

July 25, 2018
By John Fischer, VP, Advanced R&D
 
While the use of GNSS – more commonly known as GPS – is now widespread, the signal itself comes from satellites that are 20,000 kilometers away, making it fairly weak and subject to loss of signal or interference. For military operations, this presents several challenges. In a recent naval exercise, a scenario of GPS denial triggered up to 48 shipboard systems to generate alerts when GPS was lost. This shows how GPS is so pervasive and deeply integrated into many military systems for air, land and sea.

M-Code Receiver Testing: The Time is Now

June 19, 2018
By Lisa Perdue, Product Manager
 

M-Code – it is here. Public Law 111-383, Section 913 requires all military GPS user equipment purchased after FY 2017 to be M-Code capable, unless a waiver is issued the Secretary of Defense.

One reason for the Secretary of Defense to issue this waiver has been the unavailability of M-Code user equipment. With Military GPS User Equipment (MGUE), or M-Code receivers, becoming available to vendors, now is the time to start getting serious about integration and performance testing of MGUE and systems that rely on it.

The Critical Role of PNT for Special Operations Forces

May 14, 2018
By Mike Sutton, Applications Engineer
 
Orolia had the privilege of participating in the Special Operations Command (SOCOM) Technical Experimentation event at the Muscatatuck Urban Training Complex, Indiana in late March. During this event, the Army scouted new technologies that provide positioning, navigation and timing (PNT) in GPS-denied environments.
