FAQ
How does INS fusion help maintain fleet tracking when GPS signals are jammed or spoofed?
INS fusion uses an Inertial Navigation System with internal sensors (accelerometers and gyroscopes) to calculate position, speed, and heading when GPS drops out. It provides dead reckoning from the last known GPS fix, ke...

Why is network latency particularly problematic for sanctions compliance in maritime tracking?
Network latency over satellite links can delay position packets by even 30 seconds, making it appear that a ship skirted an exclusion zone when it actually passed safely. This data error multiplies when generating automa...

What are the critical features needed in a GPS system for sanctions-compliant maritime monitoring?
A compliant system needs to deliver immutable, timestamped logs, integrate multiple data sources (like GPS and AIS), automate report generation, cross-check real-time data against updated sanctions databases, and provide...

How often do sanctioned shipping lanes change and why is this important for monitoring systems?
Sanctioned shipping lanes change dynamically based on diplomatic shifts, with new corridors designated and existing ones altered. Monitoring systems must update these geofences at least daily, as weekly or monthly update...

What is the biggest risk when using standard GPS tracking for sanctions compliance in shipping lanes?
The biggest risk is data latency or loss creating gaps in position history. If an auditor sees a 15-minute gap in a high-risk zone, they'll assume the worst, which can lead to frozen assets or revoked licenses. Standard...

What are the signs that indicate when to tune, reconfigure, or replace a fleet tracking system?
You can tune your system (update firmware, adjust antenna placement) if position drift is under 20 meters and happens sporadically. You need to reconfigure the entire telematics stack if data gaps align with specific cel...

When should fleet managers consider replacing their current GPS trackers with multi-band BeiDou units?
Only replace current GPS trackers with multi-band BeiDou units if you have a clear, recurring problem that dual-frequency BeiDou specifically fixes, such as consistent errors over 10 meters in your area that impact payro...

Why does advanced GPS hardware sometimes fail to solve fleet tracking problems?
Advanced GPS hardware alone doesn't solve all tracking problems because it addresses only one part of the system. Multi-band capability does nothing for network latency in the telematics pipeline, errors from poor vehicl...

What are the practical limitations of BeiDou L1/L2 multi-band anti-jamming receivers for fleet tracking?
While BeiDou L1/L2 receivers use two frequency bands to fix ionospheric delay and have anti-jamming capabilities, they still face practical limitations. In dense urban corridors, they can take 3-5 seconds to re-acquire s...

How can we tell if our current fleet tracking system can handle GPS dark zones?
Review your trip history for recurring 'straight line' trails or long periods with no position updates on specific routes. If your system shows a vehicle jumping 10km after a gap, it's not handling the dark zone properly...

What's the biggest compliance risk with GPS dark zone gaps for fleets?
The biggest compliance risk is unlogged mileage and time. In regions with strict digital tachograph and border crossing rules, a long gap in the log can be interpreted as device tampering or an unauthorized stop, which t...

How does predictive rerouting work before GPS signal is lost?
Advanced systems use historical trip data and 3D terrain maps to identify fixed blackout zones. As a vehicle approaches a known zone, the system calculates and validates an alternative route using secondary road data, pr...
