Success Stories

We are a team of enthusiastic developers who practice their long-standing technical expertise to achieve the highest possible customer satisfaction

“GPSPATRON provides an excellent tool for GNSS signal quality analysis. With an embedded spoofing/jamming detection and classification algorithms, we create a resilient synchronization system.”

Michael Vekselman



Svetlana Starostina Photo Moscow Exchange

“Joint experiments with GPSPATRON specialists allowed us to estimate vulnerabilities of time servers to intentional and non-intentional GPS spoofing, to obtain statistics on the quality of GNSS signals at antenna installation points. Research carried out with GPSPATRON will help us improve the architecture of our timing system, making it resistant to even the most complex, targeted attacks.”

Svetlana Starostina

Head of Hardware Support Department,

Can the existing GNSS antenna be shared between a time server and a GP-Probe?
What is the difference between synchronous and asynchronous spoofing attacks?
Why does the GP-Probe require external PPS?
Can the GP-Cloud application be installed before the firewall?
Can the existing GNSS antenna be shared between a time server and a GP-Probe?

Yes, sure. You can use GP-Divider. It is a two-way RF power divider with a 10 mA current simulation. The current simulation is needed for the time server with the antenna preamplifier current measurement.

What is the difference between synchronous and asynchronous spoofing attacks?

In an asynchronous spoofing attack, the generated signal can differ from the original one in a variety of parameters like coordinates, time, etc. Synchronous spoofer generates a counterfeit signal that is identical to the genuine. Asynchronous attacks are easy to detect due to a sharp shift in the parameters. Synchronous attacks are much more difficult to execute but they allow attackers to unnoticeably shift time or coordinates. Learn more in our article.

Why does the GP-Probe require external PPS?

It is not a requirement at all. You can connect PPS output of the time server to the PPS input of the GP-Probe and control the phase offset. It is an additional function of the system for controlling the health of the time server in real-time

Can the GP-Cloud application be installed before the firewall?

Affirmative. The GP-Cloud can be supplied under different license types. Use it in the cloud or install it on your own servers.
