Cheap GPS jammers are now a standard tool for stealing plant, machinery and high-value vehicles — they blind the tracker so the asset can't be followed or recovered. I'm the independent RF engineer who detects the jamming, locates the source, and proves what happened.
Thieves don't break the tracker; they drown it. A £30 device in a cab or a nearby vehicle silences GPS across a yard, and the asset rolls away invisible. Detection and proof is an RF-engineering job, not a tracker subscription.
Estimated annual cost of plant & machinery theft to UK industry.
Share of stolen unregistered plant that is ever recovered.
Cost of the jammer that defeats a tracking system worth far more.
Independent RF work the tracker companies can't offer — because I don't sell the tracker, so there's no agenda in the findings.
Trackers going dark in the same yard? I sweep the site to confirm whether GPS jamming is active, when it happens, and how strong it is — turning "we think something's wrong" into a measured fact.
Direction finding to trace an active jammer back to its source — a device in a specific cab, a vehicle parked across the road, or a unit hidden on a machine.
Impartial, documented proof that jamming occurred — frequency, levels, timing, location — for insurance claims, loss adjusters and legal disputes. Independent evidence carries weight a supplier's report doesn't.
Assess how exposed a yard or fleet is to jamming and advise on resilience — vendor-neutrally, because I've nothing to sell you but the engineering.
Check returned hire vehicles or plant for a fitted jammer — used to evade telematics or as a precursor to theft — before the next hire goes out.
Sweep high-value cars, vans and assets for jamming devices and confirm whether a tracking blackout was interference or a fault.
No hardware to push, no subscription to protect. The finding is the truth about your RF environment — which is exactly why it stands up for an insurer or a court.
Using or supplying a jammer is a criminal offence in the UK. This service is entirely defensive: I detect, locate, document and advise. I never supply jamming equipment or help defeat lawful tracking.
An RF and microwave engineer with a counter-surveillance background — finding signals that don't want to be found is the core craft, not a sideline.
The service finds jamming when you call. The next step is a device that watches the GNSS band continuously at your yard, on a machine or in a vehicle — and the moment it sees jamming, it acts: sounds an alarm, alerts your team, or notifies a monitoring centre.
Describe what's happening and I'll tell you whether it's jamming — and what proving it would take.
