HIL testing is an essential step in the verification process of the Model-Based Design (MBD) approach. HIL testing is usually the last step before testing in the field and after Model-In-the-Loop (MIL), Software-In-the-Loop (SIL) or Chipset-In-the-Loop (CIL). This step is critical because it involves all the hardware and software that will be used ...

Description GNSS signal spoofing consists of broadcasting fake signals –over the real GNSS signals– in order to take control of a GNSS receiver that will continue to track those signals in error. GNSS is very sensitive to this type of attack due to the weakness of satellite signals at the earth's surface and the fact that these signals are public a...

Problems it Solves When testing self-driving and driving assistance systems, GNSS simulators can generate a signal to represent the vehicle. But how those vehicles interact with other vehicles with different trajectories and speeds, handle scenarios like crash avoidance, and perform in GPS and GNSS-denied environments can make all the difference in...

In 2013, the Federal Communications Commission fined a person almost $32k for using a device intended to evade the fleet management tracking system on his company vehicle. The device in question: a GPS jammer. The incident occurred at the Newark Airport after FAA and NJ Port Authority officials struggled for over two years to determine why the new ...

Adjusting Clocks for Daylight Saving Time: Daylight saving time comes twice a year, once in March and again in November. This can be a big hassle for maintenance teams, facility managers, IT staff, and anyone else in charge of keeping a building running smoothly. Adjusting for daylight saving time is easier if you have a synchronized clock system t...

GNSS is well-known for its ability to provide a position with sub-meter accuracy. However, it is less well-known that GNSS provides a very convenient way of obtaining nanosecond (or even sub-nanosecond) timing accuracy via a GNSS receiver. Indeed, in addition to the three spatial dimensions, GNSS enables the user to compute the clock bias and the d...

Customers frequently seek information and recommendations from Orolia about hardening security, including general guidelines about available network security features, jamming and spoofing deterrence, bug fixes, and networking-related issues. Sometimes they're in search of specific practices for time servers and clients. Sometimes, because SecureSy...

Merger to Deliver High-End Performance and Ultra-Accurate Timing and Frequency Products for Commercial, Critical Infrastructure and Military Markets Worldwide Orolia, the world leader in Resilient Positioning, Navigation and Timing solutions, announced today that it has entered into a definitive agreement to acquire Seven Solutions, a global innova...

Who Should Read This White Paper? Network and System EngineersNetwork and System ArchitectsNetwork and System AdministratorsDirectors/Managers of IT InfrastructureCTOs By Pritam Kandel Introduction Network time service is not something many businesses think about as a key component of their critical infrastructures. In fact, it is often overlo...

Which clock is used as the reference for all other clocks How to transfer the time from the reference clock to all other clocks The solution is to use a master clock as your reference. Master clock systems are used in a wide variety of applications and industries including aerospace and defence, broadcast, radio and telecom, network systems, financ...

Every day, all of us use this little technological miracle called GPS to take advantage of precise and trustable position, navigation and timing (PNT), all over the world. More than 2,000 billion Euros of critical infrastructures around the world are directly dependent upon GPS every day – including public and private, aerospace and defense, smart ...

By Robyn Federman, Head of Global Commercial Marketing for Orolia Most think of GPS as simply a way to get directions from their smartphone, or to tell a friend where they're hanging out. Those of us who develop resilient positioning, navigation and timing solutions (PNT) for a living know that there's a lot more to it. GPS generates about $1.4 tri...

By David Sohn, Solution Architect (And Which One Do You Really Need?) NTP (Network Time Protocol) and SNTP (Simple Network Time Protocol) are similar TCP/IP protocols in that they use the same time packet from a Time Server message to compute accurate time. The procedure used by the Time Server to assemble and send out a time stamp is exactly the s...

By Ron Dries, Applications Engineer Monitoring and managing PNT devices that can be spread across the globe can be challenging. It is also necessary to ensure the devices are configured and running properly. In certain applications, there could also be the need to schedule a task or automate some functionality of a PNT device. The built-in web GUI ...

By David Sohn, Solution Architect A leap second is a discontinuity in the world's official timescale and is a risk for those developing and maintaining GPS/GNSS systems and/or managing a time synchronization deployment. The last leap second occurred on December 31, 2016. This blog is to help you understand the leap second vulnerability and plan ahe...

Nearly 200 SecureSync® Time Synchonization Servers for U.S. Enroute Radar Systems Background FAA employs a variety of radar types for short-, medium- and long-range air traffic control requirements. Those different radars require different types of timing signals and outputs to suit their operations. Orolia was selected by the FAA for this competit...

Now your digital clocks don't have to be just used to show time, they can also show daily messages like news and event reminders. In a crisis situation, you can deliver critical information to the areas that need to know. Digital Clock Messaging is an advanced, powerful communication platform that delivers better communication and productivity thro...

What Is NTP Over Anycast? NTP (Network Time Protocol) over Anycast mode is a software technology that allows two (or more) NTP servers to sync clients via a single IP address. NTP is a packet network-based synchronization protocol to sync a client clock to a network master clock. Anycast is a networking methodology using standard routing protocols ...
