FAQ
What is the most common non-obvious compliance risk from GPS signal loss?
The corruption of timestamps is the most significant risk. Position data without accurate, synchronized UTC time becomes worthless for compliance. Many interference events distort timing data, making entire days of posit...

Can shipping companies simply explain GPS issues to authorities after they occur?
While explanations can be attempted, the burden of proof is high. Maritime authorities require continuous, unbroken, and reliable data. Post-event explanations are often viewed as excuses rather than evidence, as the com...

How does GPS interference lead to sanctions breaches for shipping companies?
GPS interference can corrupt a vessel's AIS position data, making it appear on official records that the vessel visited prohibited ports or entered restricted waters. This false data constitutes a reportable sanctions br...

Which regions have the highest GPS jamming risk for shipping?
The highest risk areas are near active military zones or testing areas including the Eastern Mediterranean, Persian Gulf, Black Sea, and parts of the South China Sea. However, jamming effects can travel hundreds of miles...

What solutions are available for ships facing persistent GPS jamming?
Ships have three main approaches: 1) Tune by adding backup signals like GLONASS or Galileo, 2) Isolate by installing dedicated inertial units and training crews on manual fixes, or 3) Redesign the entire navigation pipel...

What are the risks of treating GPS jamming as just a temporary signal issue?
Treating military-grade GPS jamming as a temporary signal issue is dangerous because delays in switching to full manual procedures can lead to accidents. Crews might misread compasses or not account for currents, and sti...

How does military GPS jamming affect civilian shipping operations?
Military GPS jamming causes operational blindness for ships, leading to instant loss of primary positioning. It freezes AIS screens or shows incorrect coordinates, causes ECDIS alarms, and creates cascading failures in s...

What strategies can fleet managers use to handle LORAN backup systems?
Fleet managers can tune their platforms by widening alert thresholds and geofence radii, reconfigure with hybrid systems that switch between LORAN and available GNSS signals, or replace single-source positioning with sen...

What compliance risks does LORAN's signal drift create for fleet operations?
LORAN's positional drift (tens to hundreds of meters) can invalidate electronic logging device (ELD) records during audits, cause inaccurate geofenced site entries/exits leading to wrong billing, and trigger false unauth...

What are the real-time tracking implications of using LORAN for fleet management?
LORAN introduces significant signal lag due to radio wave travel time, causing vehicle locations to appear 450-800 meters behind their actual position. This creates inconsistent reporting across fleets, makes synchronize...

Will existing GPS trackers work with LORAN signals?
No, standard GPS trackers cannot work with LORAN signals because they lack the appropriate antenna and decoder for LORAN's low-frequency radio waves. You would need dual-system receivers or separate LORAN-only devices, w...

How accurate is Iran's LORAN system compared to GPS for fleet tracking?
Iran's LORAN system provides accuracy around 100-500 meters, while standard GPS offers 5-10 meter accuracy. This makes LORAN suitable for regional location awareness but problematic for precise asset tracking, lane-level...
