FAQ Answer
How can I tell if my ship is being jammed versus just having a bad GPS signal?
Support Context
Why this answer matters
This FAQ is sourced directly from our support database. It helps teams deploy GPSController faster, reduce onboarding friction, and understand platform compatibility for real-world fleet operations.
Answer summary
Jamming usually causes a complete, simultaneous loss of all GNSS constellations (GPS, GLONASS, Galileo) and you'll see a rapid drop in the signal-to-noise ratio in the raw device diagnostics. A bad signal might just weaken one constella...

When should I consider upgrading my fleet tracking system to prevent spoofing?
You should consider upgrading when you can't trust location data for core operations like verifying deliveries or getting reliable geofencing alerts for importa...
Can GNSS spoofing affect multiple vehicles in a fleet simultaneously?
Yes, absolutely. A powerful transmitter near your yard or depot can drown out real GPS signals for every vehicle and tracker in the area, making it appear as if...
What are the main compliance risks for delivery fleets from GNSS spoofing?
GNSS spoofing makes your operational records fraudulent. This includes ELD logs for driver hours, geotagged proof-of-delivery documents, and route histories. If...
How can I distinguish between GNSS spoofing and normal GPS signal loss in my fleet?
Look for physically impossible data patterns. Spoofing often shows sudden huge location jumps, steady directional drift, or vehicles appearing in impossible loc...
Can GPS jamming detection software differentiate between natural signal blockage and active jamming?
Usually no. Most software cannot tell the difference between natural signal blockage (like a metal building) and active jamming. This often leads to false posit...
When should I replace my tracking system instead of just upgrading software?
Replace when your current hardware lacks RF sensing capability and you face high-theft risk or strict compliance needs. Software alone cannot generate the foren...
