Six practices

Position and time you can still trust.

Independent consultancy across navigation, anti‑jam antennas, electronic warfare, UAV integration, survey mapping and applied machine learning.

Four failure modes.

Denial and deception are not one problem. Each needs a different mix of antenna, receiver and procedure.

01 / Denial

Jamming

Noise floor raised until the receiver loses lock.

02 / Deception

Spoofing

A false fix, with no loss‑of‑lock warning.

03 / Delay

Meaconing

Genuine signals, rebroadcast late.

04 / Accident

Unintentional

Repeaters, harmonics, your own platform.

How we work.

  1. Scoping call

    One hour. No charge.

Before you send anything technical

No controlled or classified data by ordinary email. Start unclassified; we will agree a handling route first.

Start with the problem.

Platform, environment, and the decision you need to make. If we are not the right people, we will say so.
