Interference detection: a jammer in a van located from three monitoring stations. The loop, step by step: 1. Three antennas ring a stretch of road. 2. The chain from source to console stands ready. 3. A vehicle carrying a jammer drives by. 4. Each antenna sees the noise at its own moment. 5. Time and place are fixed to every sample. 6. Arrival times reach the edge. 7. Relays carry the packets without reading them. 8. The edge verifies every signature first. 9. The edge triangulates the source on the road. 10. Only a confirmed result leaves the edge. 11. The enforcement desk receives the position. 12. The console shows the evidence with the alert. 13. The jammer’s track is followed to the stop. 14. Sensors check that the response worked. 15. The whole chain is archived for audit. 16. Everything settles back to idle.

At a glance

GNSS interference monitoring

Fixed sensors that detect and characterise GNSS interference near critical sites; detection and reporting only. In interference detection, part of Positioning, navigation and timing, the interference, jamming and spoofing detection layer holds GNSS interference monitoring, drawn against ICAO Doc 9849 and ITU RR Art.

Jamming and spoofing found, located and logged

Positions drive autonomous trucks; timestamps order every event in a network. When a receiver is jammed or spoofed, both can be wrong while looking perfectly normal. Integrity has to be designed and measured, because a degraded signal rarely announces itself to the systems that depend on it.

  7. Vertroue

    Proved before it is trusted

    A node joins a network for interference detection only after its hardware root of trust answers an attestation challenge. Its keys stay in secure hardware, its software arrives signed and every record it makes for interference detection carries a signature, so anyone downstream can check where a value came from.

  8. Bewyse

    Traced to its specifications

    We trace each part of interference detection to its specification: ICAO Doc 9849, ITU RR Art. 15 and Galileo OSNMA SIS ICD. We keep the versions, configurations and test results of interference detection as signed records, so a buyer or an auditor can check what was delivered against what was specified.

  9. Operations

    Every node watched, every incident closed

    The operations console shows every node of a network for interference detection with its state, its plan and its evidence. An alert arrives with its data and a runbook, acknowledging it opens a work order, and an incident for interference detection closes only when the operator records the cause and verifies the fix.

  10. Failure and recovery

    When a node fails, the fleet knows first

    When a node for interference detection goes silent or a sensor drifts, the node buffers its data and fails over to a second link where the site has one. The alert carries the evidence a responder needs, and the record for interference detection loses nothing and counts nothing twice.

  11. Bywerkings

    Updates in rings, with rollback

    Software and configuration reach a fleet for interference detection in rings: one canary site first, then a few, then all, each ring gated on health and data completeness. A failed gate stops the wave, and each node for interference detection returns to its last good release without a site visit.

  12. What you get

    Timing and positioning integrity

    PTP grandmasters with GNSS holdover, interference detection and timing monitoring for networks and instruments. For interference detection, it goes to carriers, utilities, financial infrastructure and observatories as hardware and software or a managed service, sized to the sites they run.

01Wat dit is

Interference, jamming and spoofing detection.

The shared foundations every network and sensor depends on: how spectrum is licensed, shared and monitored, GNSS positioning and its corrections, packet timing with PTP and SyncE, grandmasters and holdover, resilient PNT alternatives, and the detection of interference, jamming and spoofing. Each technology below carries what it is, what we do with it, and the standard it is drawn against.
