WHO IT’S FOR

Built for teams that depend on GPS

DRONES

Drone operators & makers

Survey, inspection and delivery fleets that must keep flying when GNSS degrades.

ROBOTICS

Robotics & autonomy

Ground robots and vehicles that need to know where they are in tunnels, ports and cities.

INFRASTRUCTURE

Infrastructure & timing

Systems that rely on GNSS time or position, from telecoms to energy.

WHAT YOU GET

Deliverables

  • Threat review: where jamming, spoofing and outages are realistic for you
  • Failure-mode analysis of your navigation stack, sensor by sensor
  • Prioritised recommendations with rough effort and cost
  • A written report, plus a walkthrough by email or call
  • 30 days of follow-up questions

HOW IT WORKS

Four steps, about two weeks

  1. Brief

    You send a short description of the system and your concerns.

  2. Scope & quote

    A written scope and fixed price within two working days.

  3. Analysis

    We review the design, data and failure modes.

  4. Report

    Clear findings, priorities and next steps.
