FAQ
Why do tamper alerts sometimes show up late or out of order in fleet tracking systems?
Network latency and cellular handoff delays, especially in rural areas, can stall the final signal. The alert timestamp reflects when the server processes it, not when the event actually occurred, creating audit mismatch...

Can a GPS tracker still send an alert if it's physically removed from a vehicle?
Only if it has a dedicated backup battery and an independent antenna. Most standard fleet trackers cannot transmit once they're unplugged and removed from the vehicle's OBD-II port or wiring harness.

How quickly should a GPS tracker alert for tampering in security-critical fleets?
For security-critical fleets, the gap between tampering and alert should be under 60 seconds. This requires devices with frequent heartbeat intervals and immediate cellular network registration upon power loss.

When should you replace an ELD device instead of troubleshooting it?
Replace an ELD device when log errors are recurrent and tied to the device's core logging function, not just cellular coverage issues. If certified diagnostics show internal memory or sensor failure, continued use risks...

At what fleet size do ELD sync issues become unmanageable?
Beyond 50-75 power units, manual reconciliation of failed logs or unassigned driving events becomes essentially a full-time job. The scale constraint becomes critical when dispatch workflows depend on accurate HOS availa...

How does ELD failure create audit risks even when GPS tracking still works?
While the GPS may continue to show location data, the ELD module is responsible for recording engine data to prove driving time. A disconnect means the legally mandated log is wrong or missing while your fleet map appear...

What happens when an ELD compliant GPS fleet tracker fails?
When an ELD compliant GPS fleet tracker fails, it creates a compliance gap where the engine data drivers see doesn't match the logs sent to the back office. This can result in incorrect status reporting (like showing 'on...

When should fleet managers consider system redesign instead of hardware upgrades for urban GNSS accuracy?
If vehicles consistently show position errors over 10 meters for more than half a minute in core operational areas, you need system redesign. For fleet-wide issues affecting billing or compliance, software-level redesign...

How many vehicles in a fleet typically experience centimeter-level accuracy failures in dense urban cores?
In dense urban cores, over 60% of a fleet can experience episodes where accuracy drops beyond 2 meters. This directly impacts scalable geofencing alerts and accurate route reporting for fleet management.

What causes sudden GNSS position drift in city environments?
Sudden drift is usually caused by loss of lock on the correction signal, forcing the GNSS receiver to fall back to standard GPS. This frequently happens during maneuvers like turning into urban canyons where buildings bl...

Does centimeter-level GNSS work reliably in downtown urban areas?
No, it works only intermittently in downtown areas. Multipath interference from skyscrapers often degrades accuracy down to several meters, which eliminates the centimeter-level advantage needed for precise geofencing an...

Why isn't an autonomous vehicle's internal GPS sufficient for fleet management?
The autonomous system's internal GPS feeds the navigation stack, not your compliance and asset tracking workflow. Fleet management requires a secondary, time-synced data stream that is often overlooked during procurement...
