FAQ
What happens to fleet management software when AIS signals go dark in conflict zones?
When AIS signals go dark, your fleet management software effectively stops being a live command center and becomes a historical data log. The software freezes the vessel's last reported position, and all automated alerts...

Why do standard commercial anti-jamming devices fail against jamming in the Strait of Hormuz?
Standard devices often fail because they can't handle frequency-hopping jammers that switch signals faster than filters can adapt. Additionally, in the mountainous terrain around Hormuz, jamming signals reflect off landm...

Why can't ships rely solely on inertial navigation systems when GPS fails in the Strait of Hormuz?
Inertial navigation systems (INS) drift over time—about 1 nautical mile per hour without GPS correction. For prolonged transit through a narrow strait like Hormuz, this error accumulates to dangerous levels, making INS u...

What is the biggest compliance risk from GPS jamming when transiting regulated straits?
The biggest compliance risk is an inaccurate Automatic Identification System (AIS) track. Authorities use this log to verify you stayed in the designated transit corridor. Jamming-induced position jumps can make it appea...

How can I distinguish between GPS jamming and just a weak GPS signal on my vessel?
Jamming causes a total loss of all GPS satellites simultaneously on your tracker's status page, while a weak signal usually shows a gradual drop of individual satellites. You might also see a constant, high carrier-to-no...

What type of anti-jamming device is most effective against sophisticated jamming in the Strait of Hormuz?
For guaranteed operation in the Strait of Hormuz in 2026, you need a modern Controlled Reception Pattern Antenna (CRPA) system that uses spatial filtering to physically block signals from hostile directions. This should...

What happens if both GPS and BeiDou signals are jammed simultaneously?
If both systems are jammed, a good telematics device switches to inertial measurement (dead reckoning using sensors) and cell tower triangulation. The GPS Controller should immediately flag a high-priority 'total GNSS lo...

How does the GPS Controller handle BeiDou backup switching?
The GPS Controller automatically switches to BeiDou satellites when GPS signal quality deteriorates. It checks the BeiDou signal against the last good inertial data first to prevent spoofed locations from corrupting logs...

What hardware requirements are needed for BeiDou backup capability?
Devices need specific multi-constellation GNSS chipsets to receive BeiDou signals. GPS-only devices cannot be upgraded via firmware to support BeiDou - the hardware must be replaced. The telematics hardware must have the...

Why is BeiDou backup essential for Middle East fleet operations in 2026?
BeiDou backup is essential because GPS signal jamming and spoofing have become common near major ports and logistics routes in the Middle East, causing vehicles to disappear from tracking screens for hours. This creates...

What is the biggest risk when using GPS Controller's estimated positions in jammed environments?
Complacency - operators trusting estimated positions as absolute truth. The system provides continuity of awareness, not GPS replacement. Successful use requires accepting uncertainty and building operational procedures...

How long can GPS Controller operate effectively using only dead reckoning without GPS correction?
Technically it can estimate indefinitely, but practically it becomes less useful after 30 to 60 minutes without position correction. The accumulating error makes the data less reliable for real-time decisions, shifting i...
