FAQ
What alternative location methods can be used during GPS outages?
Systems can use dead reckoning and cellular tower triangulation to estimate position during outages. However, this estimated location data must be correlated with other sensor inputs like door status, PTO engagement, and...

What happens to GCC fleet compliance during GPS outages in 2026?
During GPS outages, fleets need systems that switch to alternative location methods like dead reckoning and cellular tower triangulation while continuing to log engine hours, ignition events, driver ID, and other sensor...

What are the options for preparing for the 2026 OSNMA mandate?
You have two main options: reconfigure by upgrading to new OSNMA-ready hardware with dedicated secure elements to minimize tracking delays, or redesign your entire tracking workflow to account for the latency by adjustin...

How does the OSNMA delay impact maritime operations and compliance?
The 2-3 second authentication delay causes vessels' displayed positions to be 50-100 meters behind their actual location, which affects tight port maneuvers and geofence alerts. For compliance reporting, it creates times...

Can existing fleet tracking devices handle OSNMA authentication?
Most legacy maritime tracking devices cannot handle OSNMA because they lack the necessary dedicated cryptographic hardware. Attempting to enable OSNMA on incompatible units can cause system freezes, data dropouts, or cor...

What is Galileo OSNMA and how does it affect maritime GPS tracking?
Galileo OSNMA (Open Service Navigation Message Authentication) is a security feature that adds cryptographic authentication to Galileo satellite signals to prevent spoofing. For maritime GPS tracking, it introduces a man...

Why isn't a backup cellular connection sufficient protection against electronic warfare threats?
In EW zones, threats are coordinated; jamming often targets L1 and L5 GPS bands AND satcom frequencies simultaneously. Teams waste critical hours troubleshooting what they think are 'device issues' or 'server latency' wh...

When should we consider replacing our current tracking system entirely?
When your operational routes consistently pass through electronic warfare threat zones and your current provider can't integrate hardened, multi-source PNT data. If you're facing daily signal integrity alerts and manuall...

Can we rely on the ship's onboard inertial navigation system (INS) during GPS attacks?
Only for short periods. Commercial INS systems drift significantly—hundreds of meters per hour—and require periodic GPS fixes to recalibrate. Without truth data, INS error compounds, making it useless for precise trackin...

What's the biggest compliance risk from GPS spoofing for an oil tanker?
Unintentional violation of sanctioned shipping corridors or port exclusion zones. Your automated logs, powered by false GPS, will show you were in permitted waters, but terrestrial AIS or coastal radar will tell a comple...

How can I detect if my tanker's GPS is being spoofed versus just malfunctioning?
Look for impossible data signatures such as perfect, unwavering signal strength in high-risk zones combined with complete absence of normal minor coordinate 'jitter.' Spoofed signals are often too clean. Another major re...

How can I determine if my current fleet tracking system is immune to jamming?
You need controlled environment testing with a GPS signal simulator that replicates specific power and frequency hopping patterns used in modern jamming. Simple drive tests are insufficient—you must check for data contin...
