FAQ
How accurate is dead reckoning GPS tracking when GPS signals fail?
Dead reckoning GPS tracking provides directional and corridor awareness rather than street-level precision. The accuracy degrades over time without GPS correction, with an expected drift of about 2-5% of the distance tra...

What is the first sign that my current fleet tracking system might be vulnerable to GPS spoofing?
The first red flag is seeing unexplained, perfect routing compliance in areas historically known for signal issues. Another warning sign is when drivers report obvious location errors that your software dashboard doesn't...

What are the common mistakes that make GPS spoofing attacks invisible to fleet tracking systems?
Common mistakes include: 1) Assuming encrypted military-grade GPS signals make commercial fleets immune to spoofing (most fleet hardware uses civilian L1/L5 bands that spoofers can overpower), 2) Relying only on jamming...

Why is the Middle East considered a high-risk region for GPS spoofing attacks on fleets?
The Middle East is high-risk due to several factors: high-value cargo moving through the region, complex geopolitics, and extensive remote infrastructure. This combination creates both motive and opportunity for spoofing...

How does GPS spoofing detection work in fleet tracking software?
GPS spoofing detection works by analyzing the GPS signal itself—its strength, angle of arrival, and clock drift—and then cross-checking the GPS location against other sensors like inertial measurement units (IMU), cellul...

What is the scale problem with GNSS failures in fleet operations?
When multiple vehicles hit areas with localized interference simultaneously, it creates systemic blind spots. Dispatch sees delayed updates, but the deeper problem is losing synchronized telemetry. Fuel consumption data...

What does multi-constellation failure look like in practice?
Failure appears as 'position jitter' where a vehicle seems to drift off its route when it hasn't actually moved. The tracker rapidly switches its calculated position between weakening signals from different constellation...

How does bad GNSS data affect my fuel and maintenance reports?
It completely compromises them. Fuel performance monitoring depends on accurate location and distance to calculate consumption. If the tracker reports erratic positions, your calculated mileage becomes wrong, making MPG...

Why would all four GNSS systems fail at once in 2026?
They probably won't fail completely globally, but there's risk of localized, coordinated interference. This could be intentional jamming, intense solar weather affecting the ionosphere, or ground-based 5G interference. I...

What does multi-constellation GNSS mean for my fleet?
It means your tracker can pick up signals from GPS (USA), GLONASS (Russia), Galileo (EU), and BeiDou (China) satellites. This provides more satellites to lock onto, which should help in challenging locations like cities...

When should a shipping company overhaul its compliance data system instead of just fixing GPS issues?
The decision boundary is crossed after the first official inquiry or notice of non-compliance. Once regulatory bodies have flagged your data, simply improving GPS reliability isn't enough. You need a system redesign that...

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...
