How Electronic Warfare (EW) Systems Affect GPS and Navigation

In today’s war environment, technology has become a key factor in gaining the upper hand both on the battlefield and in the rear. Navigation, logistics, unmanned systems, and transportation—all of these depend directly on the stability of the electronic environment. That is why electronic warfare (EW) plays a critically important role today.

One of the most noticeable and, at the same time, problematic consequences of its use is the disruption of GPS. This phenomenon has already become part of everyday life and affects not only military systems but also civilian transportation, business processes, and human safety.

What is EW and why does it affect navigation

Electronic warfare is a set of technologies designed to disrupt radio signals. Its primary objective is to hinder or render impossible the enemy’s communications, equipment control, and navigation.

Modern EW systems do not operate selectively. They create a powerful jamming environment that affects all devices within the coverage area—regardless of whether it is a military system or a civilian GPS tracker.

At the same time, the radius of influence can vary significantly:

• short-range — up to 10 km
• tactical level — up to 50 km
• operational-tactical — hundreds of kilometers

In such an environment, any system that relies on radio signals becomes vulnerable.

Why GPS is particularly vulnerable

GPS works thanks to satellite signals that transmit coordinates and precise time. A receiver on the ground determines its location by analyzing these signals.

The key problem is that the satellite signal is very weak. Under normal conditions, this isn’t a problem, but during active electronic warfare operations, even relatively minor interference can completely destroy the accuracy or availability of navigation.

In fact, GPS has no “anti-spoofing” protection at the basic level, so it is easily susceptible to both jamming and spoofing.

Main Ways Electronic Warfare Affects GPS

The impact of electronic warfare on navigation manifests in several key forms:

• Jamming — the signal simply disappears, and the device cannot determine coordinates
• Spoofing — signal substitution, causing the system to receive false coordinates
• Signal distortion — navigation operates erratically, with significant errors

Spoofing is particularly dangerous. It is precisely this that leads to situations where a car or smartphone “moves” to another continent, while the system continues to consider this data reliable.

Practical impact on transportation and logistics

In the transportation sector, the impact of electronic warfare is systemic and affects all processes—from dispatching to financial accounting.

First and foremost, control over transportation is compromised. The dispatcher either cannot see the vehicle at all or receives incorrect coordinates. As a result, it becomes impossible to accurately determine the vehicle’s location, speed, or route.

Additionally, serious distortions arise in analytics. For example, due to “jumps” in coordinates, the system may record thousands of kilometers of mileage in a short period of time. Combined with actual fuel consumption figures, this creates completely illogical data that cannot be used for business management.

Logistics itself also suffers: delivery deadlines are missed, route planning becomes complicated, and chaos ensues in the fleet’s operations. In critical cases, this can lead not only to financial losses but also to risks to the safety of drivers and vehicles.

Unobvious consequences: more than just navigation

The impact of electronic warfare is not limited to coordinates. GPS is also used as a source of precise time, and this is precisely why additional problems arise.

In many cases, devices begin to display the date and time incorrectly—sometimes with a discrepancy of years. This, in turn, affects the operation of vehicle systems, including maintenance reminders or even errors in the onboard computer.

Modern vehicles also use GPS for various “smart” functions. If the system receives incorrect coordinates, it may adjust climate control, brightness, or other settings based on a false geolocation.

A separate issue is communication disruption. Since GPS monitoring often works in conjunction with mobile networks, electronic warfare (EW) can simultaneously block data transmission. In such cases, the system loses control entirely.

How to Mitigate the Impact of Electronic Warfare

Despite the complexity of the situation, there are approaches that can significantly reduce risks:

• using alternative positioning methods (e.g., LBS)
• storing data on the device and transmitting it after communication is restored
• retrieving technical data via the CAN bus independently of GPS
• using backup communication channels

Equally important is the regular monitoring of data and an understanding of the nature of disruptions. In many cases, it is the human factor—the ability to interpret a situation correctly—that allows critical errors to be avoided.

Electronic warfare is fundamentally changing the role of GPS in the modern world. Navigation is no longer a guaranteed-accurate tool—it is becoming just one of many sources of information that requires verification.

Under such conditions, effectiveness and security depend on a comprehensive approach: a combination of technologies, backup solutions, and proper process organization.

Understanding the impact of electronic warfare on GPS allows us not only to adapt to new realities but also to maintain control over transportation, logistics, and the overall situation even in a complex electronic warfare environment.
