FAQ
What causes data gaps during GPS to BeiDou auto-switch in fleet tracking?
During the auto-switch from GPS to BeiDou, there's a 2-8 second recalibration period where the device's internal clock resynchronizes to the new satellite constellation. During this time, no valid position is reported, c...

When should operators consider upgrading their vessel monitoring system for dark zone coverage?
Operators should consider upgrading when dark zone coverage exceeds 15% of a vessel's journey and their current provider cannot guarantee a unified, auditable track. If dark zones are frequent and long, impacting securit...

What are the compliance risks when a vessel experiences AIS signal loss?
Port State Control under the IMO framework can scrutinize any gap in the continuous synopsis record. Gaps exceeding 15-30 minutes in high-risk areas trigger immediate questions about vessel activities during blackout per...

How does a GPS Controller platform handle AIS signal loss?
A GPS Controller platform bridges AIS gaps by fusing satellite positioning with predictive dead reckoning. It uses vessel sensor data (gyro, log) to calculate a 'most probable position' and flags the period as estimated...

What causes AIS dark zones in Middle Eastern waters?
AIS dark zones are caused by a combination of geographic blockage, intentional jamming or spoofing by state or non-state actors, and satellite coverage gaps. In 2026, the issue is less about technology failure and more a...

How can you distinguish GPS jamming from standard hardware failure?
Look for pattern-based failures: simultaneous signal loss across multiple vehicles in a tight geographic area, paired with a sharp, identical rise in reported signal noise levels on all affected units. Standard hardware...

When should fleets upgrade to jamming-resistant GPS controllers?
When operational logs show repeated unexplained location clusters, latency spikes in specific areas, or geofence breaches without movement alerts. For fleets operating near ports, borders, or sensitive sites, jamming-res...

What's the difference between jamming and spoofing in GPS systems?
Jamming floods the frequency with noise to block real signals, causing total loss of GPS fix. Spoofing broadcasts false signals that look legitimate, tricking the receiver into reporting completely wrong coordinates. Bot...

What are the practical benefits of jamming-resistant GPS controllers for fleet operations?
They prevent critical failures like trucks showing as 'idle' in a depot yard while actually being 20 miles down the road, maintain accurate real-time vehicle tracking and billing, prevent entire dispatch maps from going...

How does a multi-frequency L1 L2 L5 GPS controller detect jamming and spoofing?
The controller receives and compares signals across three different GPS radio frequencies: L1, L2, and L5. When jamming floods the L1 band with noise, the system detects the problem by checking for the absence of L2 and...

What distinguishes a resilience platform from basic rerouting tools for conflict zone logistics?
While basic tools can reroute trucks, a resilience platform ensures continuity of data itself with features like encrypted data bursts, remote device configuration, multi-network SIMs, and integration with security intel...

How does GPS Controller handle dynamic security situations like changing geofences in conflict zones?
The system handles dynamic, rapid geofence updates from a central desk and logs every entry or exit attempt—successful or blocked. This prevents losing visibility and maintains the audit trail when geographic boundaries...
