Can GPS Trackers Be Jammed? What You Need to Know

GPS tracking technology has become an essential tool for businesses and individuals alike — helping with fleet management, theft recovery, driver safety, and asset monitoring.
But a common question we hear at EzyGPS is:

“Can GPS trackers be jammed?”

The short answer is yes — but it’s not as simple or effective as many people think. Let’s break it down.

What Is GPS Jamming?

GPS jamming involves using a device (called a GPS jammer) that emits radio frequency signals designed to interfere with GPS satellite signals. Since GPS signals are relatively weak by the time they reach the earth, a strong local interference signal can temporarily block or disrupt tracking.

These jammers are often small, illegal devices that plug into a vehicle’s cigarette lighter or USB port.

Are GPS Jammers Legal in Australia?

No. GPS jammers are illegal in Australia.

Under Australian law, devices that interfere with radio communications (including GPS, mobile networks, and emergency services) are prohibited. Using or possessing a jammer can result in significant fines and penalties.

This alone makes GPS jamming uncommon in legitimate business or everyday use.

How Effective Are GPS Jammers?

While jammers can block GPS signals temporarily, they have major limitations:

• 🚫 Short range – Usually only effective within a few metres
• 🚫 Easy to detect – Signal loss patterns are obvious
• 🚫 Unreliable – Often stop working once the vehicle moves away
• 🚫 Illegal – Risky to use

Most importantly, jamming does not disable the tracker — it only disrupts signal reception while active.

What Happens When a GPS Tracker Is Jammed?

Modern GPS tracking systems (like those used by EzyGPS) are designed to identify and respond to interference.

When jamming occurs:

• The system may show signal loss or GPS interruption
• Alerts can be triggered for abnormal behaviour
• Location data is often stored and uploaded once the signal returns
• Cellular (4G) connectivity may still provide partial tracking

This makes jamming very obvious, rather than invisible.

Can GPS Trackers Still Work Without GPS Signal?

Yes — many advanced GPS trackers use multiple technologies, including:

• 📡 Cell tower triangulation
• 🧭 Inertial movement data
• 📶 4G LTE communication
• 🔋 Internal memory for data backfill

This means even if GPS is briefly blocked, tracking data is often recovered afterward, showing movement gaps that raise red flags.

How EzyGPS Protects Against Jamming

At EzyGPS, we use commercial-grade GPS tracking solutions designed for real-world conditions, including tampering attempts.

Our systems offer:

• ✅ GPS signal loss alerts
• ✅ Real-time monitoring
• ✅ Data backfill once signal returns
• ✅ Hidden and hardwired installation options
• ✅ 4G network connectivity

For fleet operators, this provides peace of mind that suspicious activity won’t go unnoticed.

Is GPS Jamming a Real Risk for Most Users?

For the vast majority of customers — no.

GPS jamming is:

• Rare
• Illegal
• Easily detected
• Ineffective long-term

Most thefts and misuse are prevented simply by having a visible, reliable tracking system installed.

Final Thoughts

While GPS trackers can technically be jammed, modern systems are built to detect, record, and recover from interference. The risks and penalties associated with jamming make it an impractical solution for anyone attempting to avoid tracking.

If you’re looking for a reliable GPS tracking solution in Australia, EzyGPS offers trusted devices, professional support, and powerful tracking software to keep your vehicles and assets protected.
