FAQ
What's the biggest compliance risk from GPS spoofing?
It falsifies your auditable trail. If a spoofed truck appears to be at a certified weigh station or is logged as being within regulated driving hours, your electronic logging device (ELD) records become fraudulent withou...

How can I tell if my fleet's GPS is being spoofed?
Watch for data that doesn't make sense: vehicles reporting locations in impossible places (like middle of a lake without a ferry), groups of assets suddenly showing the same wrong offset in one area, or conflicts between...

How does switching to BeiDou affect geofence alerts and compliance reporting?
Latency and occasional position jumps during the GPS-to-BeiDou handoff can cause false entries or missed alerts, especially for small, precise geofences. Compliance logs may falsely show trucks idling when they were actu...

Will my current GPS trackers automatically work with BeiDou during jamming?
Only if they are multi-constellation (GNSS) devices. Many standard GPS-only trackers cannot see or use BeiDou satellites. You need to check your device specifications, as a hardware upgrade is often required to access al...

What happens to fleet tracking when GPS jamming occurs and systems switch to BeiDou?
The handoff from GPS to BeiDou isn't seamless - you'll see 'invalid position' flags in your data stream, and speed/heading data can glitch during the switch. Multiple vehicles hitting a jamming zone at once may all show...

What does 98% BeiDou accuracy under jamming really mean for fleet operations?
The 98% accuracy means BeiDou provided a position fix within its advertised error margin for 98 out of 100 position polls during tests. However, this doesn't guarantee operational reliability - the 2% failure rate create...

What are the practical implications of GPS signal loss for asset tracking systems?
GPS signal loss creates critical vulnerabilities in tracking systems. Decisions based on degraded INS data can lead to wasted resources, such as dispatching recovery teams to incorrect locations. The growing positional d...

How accurate is inertial navigation compared to GPS for tracking applications?
Inertial navigation is significantly less accurate than GPS and should be treated as a short-term bridge rather than a replacement. While INS can maintain basic navigation, positional errors can accumulate to hundreds of...

What is inertial drift and why does it occur in navigation systems?
Inertial drift is the compounding error that occurs when an inertial navigation system operates without GPS correction. Tiny, unavoidable errors in accelerometers (bias errors) and gyroscopes (drift rates) accumulate ove...

What happens when a GPS device loses satellite signal and switches to inertial navigation?
When GPS signal is lost due to jamming, spoofing, or environmental factors, the device automatically switches to its inertial navigation system (INS). This system uses gyroscopes and accelerometers to estimate position,...

When should a fleet operator consider redesigning their tracking system architecture?
Redesign becomes necessary when interference is persistent, targeted, and sophisticated enough to spoof multi-band GNSS and corrupt secondary systems. This is when the cost of not knowing true position (from safety fines...

What operational problems occur when GPS interference affects multiple vessels in a fleet?
At scale, GPS interference causes workflow collapse: dispatchers can't manually verify every position shift, automated ETA predictions become useless, safety alerts flood in based on ghost ships or phantom positions, and...
