FAQ
What's the difference between basic multi-band GPS devices and true jamming-resistant devices?
Basic multi-band devices may use extra frequencies only for faster initial lock or slightly better accuracy in clean environments, but lack dedicated hardware and signal-processing firmware to actively detect and mitigat...

How does jamming resistance actually work in a GPS tracker?
Jamming resistance works through a combination of specialized hardware (like antennas that filter noise) and software algorithms that continuously monitor signal characteristics across multiple frequencies. When it detec...

What is the main advantage of L1/L2/L5 multi-frequency GPS over just L1 GPS for fleet tracking?
The main advantage is signal redundancy and integrity. If one frequency (like L1) is blocked, reflected, or jammed, the device can calculate position using L2 and/or L5. This maintains location continuity where a single-...

What are the most effective solutions for protecting air cargo fleets from GPS spoofing by 2026?
Options include tuning existing systems with spoofing detection software, reconfiguring to use multiple data sources like cellular tower pings or inertial sensors, or replacing hardware with modern GPS controllers that c...

How does GPS spoofing affect other fleet management systems beyond just location tracking?
Spoofing impacts any system using GPS for timing, including delayed geofencing alerts, incorrect automated fuel tax (IFTA) reporting assigning miles to wrong states, and thrown-off time-based maintenance alerts. It makes...

What are the main compliance risks from GPS spoofing for regulated air cargo shipments?
The biggest compliance risks include falsification of Electronic Logging Device (ELD) and Hours of Service (HOS) records, which become invalid for DOT audits. For sensitive cargo like vaccines or food, spoofing breaks th...

How can I distinguish between GPS spoofing and normal signal glitches in my air cargo fleet?
Look for specific patterns: a vehicle showing strong GPS lock with multiple satellites but its reported location slowly drifts off known roads, or you see impossible data like sudden 500 mph jumps. Also check if GPS spee...

What defense strategies should fleet operators consider against GPS spoofing?
Fleet operators have three paths: 1) Patch - update device firmware and tighten driver policies to stop opportunistic spoofing; 2) Isolate - ground and physically inspect any asset triggering high-confidence alerts immed...

What is the critical mistake fleet managers make when receiving spoofing alerts?
The most expensive mistake is treating spoofing alerts as GPS glitches or device failures that need rebooting. Spoofing is a deliberate attack, not equipment failure. The 'reboot and retry' instinct creates critical dela...

What are the immediate consequences if GPS spoofing goes unchecked in a fleet?
Unchecked spoofing leads to phantom vehicles completing routes in fleet management software, generating false proof-of-delivery timestamps and invoices for work never done. Real assets could be used for unauthorized side...

What does a real-time spoofing detection alert actually mean for my fleet operations?
A spoofing alert means your GPS Controller platform has detected that your vehicle's reported location is being faked. The system catches discrepancies like impossible location jumps, GPS coordinates disagreeing with ine...

When should I upgrade tracking systems for high-risk logistics operations?
Upgrade when the cost of a single lost or compromised shipment—including liability—exceeds the investment in hardened, multi-source tracking technology. For operations planning routes in 2026 conflict zones, specialized...
