FAQ
What makes Iridium satellite communication more reliable than other satellite systems in conflict zones?
Iridium's L-band signal is more resistant to wide-area jamming typically used against GPS. Unlike GEO-stationary satellite systems, Iridium has lower latency, lower power requirements, and is less susceptible to targeted...

How quickly does the Iridium fallback system activate when GPS signals are lost in conflict zones?
Properly configured devices switch to Iridium fallback within 30 to 90 seconds of persistent GPS signal loss, ensuring near-continuous tracking without manual intervention.

Will multi-GNSS trackers work globally for international fleets?
Yes, different satellite constellations have better coverage in different regions worldwide. By using all four major systems, the tracker ensures optimal signal strength and availability globally, which is essential for...

When should a fleet upgrade to jamming-immune tracking systems?
Upgrade when your operation depends on uninterrupted location data for safety, security, or contractual obligations (like hazmat transport or high-value cargo). If current devices lose signal in problem areas or you expe...

What's the difference between 'jamming resistant' and 'jamming immune' trackers?
Jamming resistant trackers typically have better antennas but can only delay signal loss. True jamming immunity requires both multi-constellation reception AND onboard algorithms that can identify jamming patterns and sw...

Is jamming immunity only necessary for government or military fleets?
No, commercial jamming devices are now inexpensive and accessible. Any fleet operating in ports, near sensitive infrastructure, or transporting high-value goods is at risk. This protection ensures data continuity and com...

How does the multi-GNSS technology prevent jamming in fleet trackers?
The tracker receives signals from four different satellite constellations (GPS, GLONASS, Galileo, and BeiDou) across multiple frequencies. If one system like GPS is jammed, the device instantly switches to unaffected sat...

Is upgrading GPS controller software sufficient to prevent spoofing attacks?
No, software alone is not enough. While software can improve detection, preventing spoofing requires hardware-level changes including receivers that analyze signal structure for tampering and diversified positioning inpu...

How can you distinguish real GPS spoofing from just a bad signal?
Spoofing typically provides a strong, clear signal that feeds plausible but false information, while a bad or jammed signal usually results in complete loss of GPS fix or wildly inaccurate, jumping coordinates. Proper sp...

What are the immediate actions to take when a spoofing alert sounds on the bridge?
Immediately cross-reference the GPS position with independent systems: check inertial navigation if available, get radar fixes on known landmarks, examine the gyrocompass and log. Do not trust any automated systems takin...

What does a GPS spoofing detection alert mean for a commercial vessel?
A GPS spoofing detection alert means your vessel's GPS receiver has detected a conflict between expected satellite signal characteristics and the actual incoming signal, indicating that the reported position is being del...

How do delayed geofencing alerts create safety risks during signal jamming?
Under jamming, geofencing alerts can arrive 15 minutes late, with the vehicle already deep in a restricted grid. A three-minute delay in recalculating a route can mean the difference between a safe detour and entering a...
