Pyramid GNSS is a cybersecurity software solution designed to protect GNSS (Global Navigation Satellite System) receivers and systems from spoofing and jamming attacks. It addresses threats to satellite-based navigation and timing across multiple industries. The product consists of two components: **Pyramid DT (Detection)** A hardware-agnostic, stateless, lightweight software library that detects and alerts against GNSS spoofing and jamming attacks. It operates in connected or standalone modes and requires minimal computational resources (~2 DMIPS, 500 bytes RAM, 2KB flash). It detects data and range spoofing, time shifts, combined attacks, and multiple simultaneous attack sources using dozens of independent software mechanisms and algorithms. The library is updated continuously to address newly identified threats. **Pyramid MT (Mitigation)** A chip/hardware-level solution that both detects and mitigates spoofing attacks, enabling continuous PNT (Position, Navigation & Time) operation even during active spoofing events. It uses multi-patent, multiple-peak detection and tracking algorithms and is designed for chip-level integration, FPGA, or software-based receivers.
