Position Without a Satellite, Without a Beacon Grid

Assured PNT and GPS-Denied Operations

Centimeter-accurate position where GNSS does not reach and infrastructure cannot be installed. Basements, hulls, tunnels and contested airspace share one problem, and cameras are in scope for alternative PNT.

Get Started
No Satellite Needed
Camera-based position where GNSS is blocked, jammed or spoofed.
No Infrastructure
No tags, anchors or beacon grid to install or maintain.
Air-Gapped Deployment
On-prem, disconnected and on-device options by default.
Any Capture Source
E57, LiDAR, drone, 360 and phone scans into one map.
What is “Assured PNT and GPS-Denied Operations”?
Alternative PNT is positioning that doesn't depend on a satellite, and cameras are part of the definition. In a basement, a hull, a tunnel or contested airspace, GNSS is absent or untrustworthy. MultiSet localizes from the scene itself, with nothing mounted and nothing transmitting.

Benefits & Measurable Impact
Resilient Position
Holds when GNSS is blocked, degraded, jammed or spoofed.
Nothing to Install
Resolve 6-DoF pose from the camera alone, disconnected if needed.
Runs Disconnected
Combine with inertial and other aids; hold position through GNSS loss.

How it works
Map the Space
Import an existing scan or capture the zone; no survey infrastructure required.
Localize On Device
Resolve 6-DoF pose from the camera alone, disconnected if needed.
Fuse & Operate
Combine with inertial and other aids; hold position through GNSS loss.
Frequently asked questions
What is alternative PNT?

Positioning, navigation and timing that does not depend on GNSS. The category covers camera, terrain, magnetic and inertial methods, and it exists because satellite signals are blocked indoors and are jammable outdoors.

Is camera-based positioning in scope for assured PNT programmes?

Yes. Alternative PNT is defined to include optical methods alongside terrain, magnetic and inertial. Individual solicitations vary and some exclude optical explicitly, so read each one, but the category itself includes cameras.

How is this different from GPS-denied navigation using SLAM?

SLAM builds a map as it goes and drifts against no fixed reference. MultiSet localizes against a known map, so the pose is absolute and repeatable across sessions, devices and operators rather than relative to where the run started.

Can it run air-gapped?

Yes. On-prem, private cloud and fully on-device deployment, with no callback and no data leaving the site. Maps stay inside the customer’s own infrastructure.

What accuracy should we expect?

Sub-5 cm median with quality captures and appropriate conditions. For comparison, RTLS literature treats 10 to 30 cm as centimetre-level, and that usually arrives with tags and an infrastructure project attached.
