FAQ
What solution is recommended for reliable vessel tracking in AIS dark zones?
A hybrid tracking system using a dedicated GPS controller that logs position data and transmits it via separate satellite communications links when AIS is down. This creates an unbroken, auditable trail for both complian...

What are the main compliance risks when operating in AIS dark zones?
The primary compliance risks include inability to prove adherence to sanctioned routes, failure to maintain continuous tracking records required by regulators, and disputes over vessel locations during incidents. These c...

Why isn't standard GPS sufficient when AIS fails for ships?
While a standard GPS receiver tells the ship where it is, it doesn't automatically transmit that data to operations centers. Without a separate, reliable telematics link like satellite communications to relay GPS data ba...

What is an AIS dark zone and why is it a problem for shipping companies?
An AIS dark zone is a maritime area where the Automatic Identification System signal is jammed, spoofed, or blocked, preventing vessels from broadcasting their position, identity, or course. This creates critical visibil...

When should a fleet consider upgrading to multi-frequency jamming-resistant GPS devices?
Upgrading becomes non-negotiable when operations touch secured facilities, require unwavering ELD compliance, or dispatch into urban centers where signal denial is common. When lost signals start causing invoice disputes...

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...
