FAQ
What's the difference between 'jamming resistant' and 'jamming immune' trackers?
Jamming resistant trackers typically have better antennas but can only delay signal loss. True jamming immunity requires both multi-constellation reception AND onboard algorithms that can identify jamming patterns and sw...

Is jamming immunity only necessary for government or military fleets?
No, commercial jamming devices are now inexpensive and accessible. Any fleet operating in ports, near sensitive infrastructure, or transporting high-value goods is at risk. This protection ensures data continuity and com...

How does the multi-GNSS technology prevent jamming in fleet trackers?
The tracker receives signals from four different satellite constellations (GPS, GLONASS, Galileo, and BeiDou) across multiple frequencies. If one system like GPS is jammed, the device instantly switches to unaffected sat...

Is upgrading GPS controller software sufficient to prevent spoofing attacks?
No, software alone is not enough. While software can improve detection, preventing spoofing requires hardware-level changes including receivers that analyze signal structure for tampering and diversified positioning inpu...

How can you distinguish real GPS spoofing from just a bad signal?
Spoofing typically provides a strong, clear signal that feeds plausible but false information, while a bad or jammed signal usually results in complete loss of GPS fix or wildly inaccurate, jumping coordinates. Proper sp...

What are the immediate actions to take when a spoofing alert sounds on the bridge?
Immediately cross-reference the GPS position with independent systems: check inertial navigation if available, get radar fixes on known landmarks, examine the gyrocompass and log. Do not trust any automated systems takin...

What does a GPS spoofing detection alert mean for a commercial vessel?
A GPS spoofing detection alert means your vessel's GPS receiver has detected a conflict between expected satellite signal characteristics and the actual incoming signal, indicating that the reported position is being del...

How do delayed geofencing alerts create safety risks during signal jamming?
Under jamming, geofencing alerts can arrive 15 minutes late, with the vehicle already deep in a restricted grid. A three-minute delay in recalculating a route can mean the difference between a safe detour and entering a...

What's the biggest compliance risk with delayed tracking data during conflicts?
The risk is audit trail failure. If your GPS controller's logs show a vehicle was in a permitted zone, but actual satellite timestamps prove it was there later—after a closure order—you have no defensible compliance reco...

When should I switch from automated to manual crisis routing during signal disruptions?
The switch point is when over 30% of your fleet reports signal integrity below 50% for more than one hour. Before that, trust the controller's degraded-mode algorithms. After that threshold, manual oversight is required...

Why can't I rely on manual override when GPS systems fail during geopolitical crises?
By the time a dispatcher identifies a signal gap, pulls up vehicle history, and charts a new course, the geopolitical situation on the ground has often shifted—new roadblocks exist, fuel depots close, or diplomatic corri...

How does GPS signal jamming during conflict affect fleet rerouting accuracy?
Jamming doesn't just hide location; it injects timing errors into the GPS controller, causing it to calculate routes from wrong coordinates. A vehicle might be 2km off its last reported point, making any automated detour...
