GPS/GNSS Jamming & Spoofing Resource Center

GPS/GNSS jamming and spoofing attacks are on the rise. The combination of low-cost hardware, open source software, and tutorials on YouTube have fostered the proliferation of these malicious acts. Beyond intentional disruption, other factors such as environmental conditions and conflicts with other electronic systems can result in unreliable or even unavailable GNSS data.

Now more than ever, it’s critical to protect your GNSS-dependent positioning, navigation and timing (PNT) systems.

At Orolia, we offer comprehensive anti-jamming and anti-spoofing solutions, from initial vulnerability testing to integrated interference, detection and mitigation (IDM) solutions to ongoing testing, simulation and monitoring.

How Common is GPS Jamming? (And How to Protect Yourself)

March 19, 2018
By Jeremy Onyan, Director of Time Sensitive Networks
 

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.

Making Time Sensitive Networks Resilient Against Threats White Paper

Today's time sensitive networks rely on available and accurate positioning, navigation and timing (PNT) signals to provide leaders with the information required to make timely and effective decisions. The proliferation of GNSS-degrading and denying devices across state and non-state actors put this critical information capability in jeopardy. Learn how a combination of alternative PNT signals with traditional GNSS references makes PNT applications resilient against jamming and spoofing.

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.

GPS/GNSS Spoof Testing By Simulation

Hardening GPS/GNSS receivers against spoofing and jamming is crucial as threats are new, real and increasing. Testing with a GPS/GNSS simulator is a very effective tool for designing and evaluating countermeasures for mission-critical applications for positioning, navigation and timing. This presentation describes the application for testing spoofing.

A Holistic Approach to Trusted, Resilient PNT

Positioning, navigation and timing (PNT) services are indispensable, and providing trusted, resilient PNT solutions requires us to look beyond individual systems and methodologies to focus upon the user. An architecture that can meet this demand must include multiple systems with diverse technologies so that any single threat or source of disruption can be mitigated. This document discusses how signaling technologies such as GNSS, eLoran and STL are the complementary components of this architecture.

Using a Passive Anti-Jam Antenna to Combat GNSS Interference

Banking on BroadShield

Alternative Signals

With an encrypted signal 1000x stronger than GPS/GNSS, STL Satellite Time & Location (STL) is an ideal solution to augment GPS/GNSS signals and provide additional resiliency for critical networks.

It works indoors where other GNSS signals can't reach. It’s the perfect standalone reference when you want to "cut the cord" or when roof access isn’t an option.

8230AJ Anti-Jam Antenna

8230AJ GPS/GNSS Anti-Jam Outdoor Antenna

The Model 8230AJ is a high gain (40 dB) GNSS outdoor antenna. It uses a three-stage low noise amplifier, a mid-section SAW, and a tight pre-filter to protect against saturation by high level sub-harmonics and L-band signals. The Anti-Jam antenna rejects signals for the lower elevation angles – where most of the interference comes from.
