FAQ
What are the compliance risks of not having offline backup tracking?
The primary risk is creating unverifiable gaps in the chain of custody or hours-of-service logs during signal outages. This leads to compliance violations during audits because you cannot prove vehicle location or driver...

How does offline backup tracking work when GPS signal fails?
It uses cellular-based dead reckoning which combines the last-known GPS position, cellular tower triangulation, and vehicle sensor inputs like speed and heading to calculate and cache estimated positions. The system cont...

When should a fleet consider redesigning their tracking setup instead of just tuning it?
Redesign is necessary when signal loss consistently occurs during critical compliance events or creates audit mismatches. At this point, you need multi-source validation including GLONASS, cellular triangulation, and ine...

What is the common mistake teams make when troubleshooting GPS signal loss?
Teams often mistakenly assume cellular data equals GPS tracking. When the GPS receiver is jammed or blocked, the device might still show as 'online' via cellular, but its location data becomes stale or inaccurate. This l...

What happens to location data when a GPS tracker loses signal for extended periods?
Most tracking devices have a limited internal buffer for storing location pings during outages. Once this buffer is full, new data overwrites the old data, creating permanent gaps in trip history that can be flagged duri...

What operational risks occur when GPS signals drop in fleet tracking?
When GPS signals drop, you experience delayed geofence alerts, missed route compliance monitoring, and inability to detect silent vehicle idling. The system cannot report critical operational data, creating hidden risks...

When should fleet managers consider replacing their tracking software's jamming detection system?
Consider replacement when alert delays consistently exceed 30 seconds, false positives make up more than 20% of alerts, or the system cannot integrate jamming data with other security layers like geofencing. At this poin...

What are the compliance risks when anti-jamming alerts fail in fleet tracking?
The main compliance risk is the inability to prove chain of custody or explain unauthorized stops during audits. Missing alert logs create gaps in the required electronic record of vehicle security events, which cannot b...

Why can anti-jamming alerts be delayed in fleet tracking systems?
Alert delays occur because the software's alert engine often shares processing queues with high-volume telematics data like engine diagnostics or frequent location pings. Under loads of 50+ vehicles, jamming alerts can g...

How does GPS tracking software detect jamming in fleet vehicles?
The software monitors the GPS receiver's signal-to-noise ratio and analyzes satellite constellation data, looking for patterns of broad-spectrum noise that overwhelm legitimate signals. This is different from simply dete...

When should a fleet upgrade to anti-spoofing hardware instead of relying on software alerts?
Upgrade to hardware with anti-spoofing features when operating high-value or time-critical deliveries in sensitive areas, after confirmed spoofing incidents, or when the cost of a single compromised route (like losing va...

How can I identify if my fleet is experiencing GNSS spoofing versus routine GPS issues?
Look for 'plausible but impossible' data patterns: vehicles appearing to teleport or travel at impossible speeds, routes completed in unrealistic timeframes, clusters of vehicles reporting the same wrong coordinates, or...
