GNSS Jamming and Spoofing Solution

The FMT-SSAS-V1 Ship Security Alert System is equipped with enhanced support for multi-constellation GNSS systems (GPS, GLONASS, BeiDou) with intelligent and configurable signal selection.

If one GNSS source becomes weak, disrupted, or unreliable due to jamming or spoofing, the system can be configured over the air to another available source.

Understanding GNSS Jamming & Spoofing

GNSS Jamming

GNSS jamming occurs when external radio frequency signals disrupt or overpower satellite signals, resulting in:

  • Loss of positioning data
  • Intermittent tracking failures
  • Reduced navigation accuracy
  • Gaps in vessel monitoring systems

Jamming is often unintentional (environmental or electronic interference) but can also be deliberate in sensitive regions.

GNSS Spoofing

Spoofing is more critical. It involves the transmission of false GNSS signals that mislead a receiver into calculating incorrect positions.

This can lead to:

  • False vessel location reporting
  • Misleading route tracking
  • Delayed or incorrect emergency response
  • Operational confusion in fleet monitoring systems

Unlike jamming, spoofing can be harder to detect because the system still shows a “valid” position.

Operational Challenges for Fleet Owners

GNSS interference directly impacts:

  • Vessel tracking reliability
  • Fleet visibility across regions
  • Emergency response accuracy (SSAS)
  • Compliance and reporting integrity
  • Operational planning and coordination

In modern maritime environments, position trust is as important as position availability.
