FAQ
What specialized GPS technologies are needed for accurate rail track inspection?
Rail inspection vehicles require correction protocols like RTK (Real-Time Kinematic) or precise point positioning (PPP) services for sub-meter accuracy. They also need robust dead reckoning systems using inertial measure...

When should rail operators consider specialized GPS controllers instead of standard fleet tracking systems?
The threshold is when compliance or engineering teams start manually correcting location data, or when the cost of potential re-work due to location errors exceeds the investment in a precise system. If work defines asse...

How do tunnels and urban areas affect GPS tracking for rail inspection vehicles?
Total signal loss in tunnels creates data gaps. Systems without robust dead reckoning—using wheel encoders and gyros—will often draw straight lines between signal points, falsely showing the vehicle traveling off the tra...

What are the consequences if GPS logs show a rail inspection vehicle was on the wrong track?
In regulatory audits or incident investigations, discrepant logs create immediate doubt about all recorded work. This can lead directly to fines, contract penalties, or mandatory re-inspection of entire line segments at...

Why is standard vehicle GPS not accurate enough for railway track inspection vehicles?
Standard automotive-grade GPS has a typical 5-10 meter circular error probability (CEP), which is greater than the width of the track bed itself. This level of uncertainty makes it impossible to definitively tie maintena...

What are common signs of fuel fraud revealed by location mismatches?
Common signs include: overnight refueling at truck stops when the vehicle was parked at a depot miles away, mismatches clustering on weekends for vehicles supposedly undergoing maintenance, and transactions occurring in...

What is the minimum GPS update frequency needed to reliably catch fuel fraud?
To reliably catch fuel misuse, you need GPS updates at least every 60-90 seconds during operating hours. Batch updates every 5-10 minutes create gaps where drivers can fuel up and return to route without the system detec...

Can GPS signal delays cause false fraud alerts?
Yes, GPS signal delays can cause false alerts in dense urban areas or tunnels where signal loss is brief. However, systems account for this with a configurable time buffer (typically 2-5 minutes). Mismatches lasting long...

What triggers a fuel card transaction location mismatch fraud alert?
A fraud alert is triggered when the geofence around a fuel pump's address and the GPS ping from the assigned vehicle don't intersect at the exact transaction timestamp. The system flags variances outside a configurable r...

When should we upgrade from a standard fleet tracker to a hardened security controller for armoured vehicles?
The decision hinges on compliance and liability. If you merely need to know a vehicle's general location, a commercial tracker might suffice. But if you need an immutable, court-admissible log of a high-value asset's exa...

How important is geofencing for cash transit routes?
It's the primary real-time control layer. For transit, you need dynamic corridor geofencing that alerts if the vehicle deviates from the planned route. The real risk is a delayed or missed alert due to telemetry batching...

Can signal jamming really disable vehicle tracking for armoured cash transit?
Yes, easily. Low-cost jammers flood GPS frequencies, causing standard devices to lose fix. A proper security-grade controller detects this jamming as an attack signature, triggers an immediate tamper alert via cellular b...
