FAQ
Does P code encryption provide end-to-end security for fleet tracking data?
No, P code encryption only secures the link from the satellite to the receiver. After that, location data is transmitted over cellular or satellite networks using standard commercial encryption (if configured). This crea...

What is the operational reality of using P code encrypted GPS for fleet tracking?
P code encryption provides more secure and precise signals that are harder to spoof, but it introduces a 300-800 millisecond delay due to decryption. At fleet scale (e.g., 500 vehicles), key rotations can cause temporary...

How does GPS spoofing evidence differ from standard GPS tracking data?
GPS spoofing evidence requires controller-level signal authentication and timestamped raw NMEA data that proves the GPS receiver was actually deceived. This includes RF signal metrics, signal power anomalies, and diagnos...

Can older vessel tracking systems be upgraded to meet 2026 evidence standards?
Yes, but it requires installing modern GPS receivers/controllers with spoofing detection firmware. You also need to ensure your data backhaul has sufficient bandwidth and storage to handle the increased diagnostic data v...

What's the biggest mistake in GPS evidence collection for maritime claims?
Configuring GPS tracking for efficiency rather than evidence. Most systems filter out 'invalid' positions with high HDOP or low satellite counts, which are exactly the signals that indicate active spoofing or jamming. By...

Why can't standard GPS tracking maps prove spoofing to insurers?
Standard maps only show processed location points, which is the result of spoofing. Insurers need proof of the cause - the fake signals themselves. They require technical data from the GPS controller showing signal anoma...

What specific data from a GPS controller is needed to prove GPS spoofing for insurance claims?
You need raw RF-level evidence including signal-to-noise ratio (SNR) anomalies, sudden changes in reported altitude, signal authentication flags, raw carrier phase measurements, full timestamped NMEA sentences (not just...

What are the risks of using standard GPS trackers in conflict zones?
Standard GPS trackers become liabilities when their single-frequency signals are jammed or spoofed, creating dangerous blind spots in situational awareness. The highest risk is making decisions based on false data - your...

When should logistics operations upgrade to frequency agile GNSS receivers?
Upgrade becomes necessary when standard tracking fails repeatedly on critical runs, especially in known contested corridors. If you're experiencing data blackouts despite using geofencing alerts and secondary data checks...

What's the difference between multi-band support and true frequency agility?
Multi-band support means a device can physically access multiple frequency bands, but true frequency agility requires intelligent anti-jam and anti-spoof software algorithms. A receiver might access L2 bands but without...

How does a frequency agile GNSS receiver maintain signal in conflict zones?
A frequency agile GNSS receiver constantly monitors multiple GNSS frequency bands (L1, L2, L5) and checks for signal strength and integrity. When it detects interference or signal degradation on one band, it rapidly retu...

When should a fleet upgrade their management software for electronic warfare resilience?
Upgrade when the cost of a single failure (lost high-value shipment, safety incident from misrouted vehicles, or regulatory fine for falsified logs) exceeds the investment in a resilient system. If operations are in or e...
