Designed for Persistent and Wide-Area Interference

SPECTRA-I 1600 is engineered for environments where GNSS interference may be continuous, high-power, or geographically distributed.

The system maintains stable Position, Navigation, and Timing (PNT) performance during extended operation, making it suitable for both mobile and static deployments where GNSS availability is mission-critical.

Wideband GNSS acquisition enables rapid detection of interference activity, while spatial processing and digital mitigation work together to reduce jammer impact over time.

Simultaneous Multi-Band GNSS Protection

The system provides concurrent protection of L1, L2, and L5 GNSS signals (or user-specified custom bands), supporting all major constellations including GPS, Galileo, and BeiDou.

Parallel multi-band processing ensures navigation continuity even when interference is focused on specific frequency regions, without reliance on RF band switching.

This capability is particularly valuable for installations and platforms that must remain operational under evolving electronic attack conditions.

Digital-First Architecture for Long-Duration Operation

SPECTRA-I 1600 uses a direct-conversion sampling architecture, transferring the captured GNSS spectrum directly into the digital domain. This enables:

• adaptive suppression of narrowband and structured interference
• effective handling of multi-tone and swept jammers
• repeatable, stable performance during long deployments

The digital-centric design reduces RF complexity while supporting high dynamic range and sustained suppression capability.

Optional Electronic Warfare Awareness

(Configuration-dependent)

For applications requiring enhanced situational awareness, SPECTRA-I 1600 can be configured with optional capabilities that extend beyond core GNSS protection:

• Jammer direction indication for threat localisation
• Interference characterisation to assess jammer behaviour

Threat reporting and event logging for operational analysis

Interfaces to navigation, mission, or EW management systems

These options allow SPECTRA-I 1600 to contribute to a broader operational or EW picture while remaining focused on GNSS resilience.

Suitable for Large Platforms and Fixed Deployments

SPECTRA-I 1600 is well suited for applications where continuous operation, mechanical robustness, and sustained performance are required, including:

• large surface vessels and maritime platforms
• coastal and port installations
• fixed infrastructure and reference sites
• land-based command, control, or security installations

The integrated design minimises external RF cabling and supports long-term deployment in demanding environmental conditions.
