Optimised Multi-Band GNSS Protection

SPECTRA-I 400 is optimised for dual-band GNSS protection, supporting:

• L1/L2 protection as the standard configuration.
• Custom band configurations selectable according to customer requirements

This targeted approach ensures robust Position, Navigation, and Timing (PNT) performance under heavy jamming activity.

Integrated, Digital-First Architecture

The SPECTRA-I 400 employs a direct-conversion sampling architecture, bringing the captured GNSS spectrum directly into the digital processing domain. This enables:

• precise suppression of narrowband and structured interference
• efficient digital filtering without excessive RF complexity
• reduced component count and lower power consumption

By integrating the antenna and electronics into a single unit, the system minimises cabling losses, simplifies installation, and improves overall robustness.

Designed for Low SWaP Platforms

SPECTRA-I 400 is specifically engineered for applications where power efficiency, compact form factor, and system simplicity are critical. The optimised architecture delivers effective GNSS protection without the size, weight, and power penalties associated with larger EW-focused solutions.

Typical application areas include unmanned systems, tactical platforms, and other embedded navigation systems requiring dependable GNSS operation under interference.
