Defence engineering, designed and built in Sweden.

We have been engineering precision systems in Sweden since 2000. Defence forces and industry partners come to us for applications where the measurement has to be right.

All electronics and software are designed in-house, keeping quality control and engineering expertise inside the company.

Three generations of the Tensec tracker side by side — Built to the size the requirement calls for. Three generations of the same tracker, each specified for a different installation, from a cast pedestal to a flat plate. The apertures went the other way: larger, not smaller, because reach depends on how much light the optic can gather.

How we work

We do not deliver pre-built standard systems. Every project starts with your specific requirements, and our engineers work alongside your team through design, delivery and commissioning. We support what we deliver ourselves, for as long as the system is in service. No reseller, no third party.

Diagram: impacts plotted against a target area, with the measured error from the target centre marked — Where a system starts, and how it gets built. The scoring geometry worked out first: impacts against the target area, and the error measured from its centre. Then the same geometry compiled and running on the bench, against live cameras.

Development bench: source code beside the tracker software running live on thermal and daylight cameras — Where a system starts, and how it gets built. The scoring geometry worked out first: impacts against the target area, and the error measured from its centre. Then the same geometry compiled and running on the bench, against live cameras.

Track record

Our engineers have spent their careers in military systems engineering, and that discipline is why companies outside defence also come to us to design their products.

Our systems are in service with armed forces and national defence authorities in several countries.

Made in Sweden

All Tensec systems are designed and built in Sweden, and every system is ITAR-free.

CAD render of a sensor head: thermal objective, daylight camera, inertial unit and computer inside a machined housing — A sensor head from the CAD model, and the manufacturing drawing for one of its machined parts. Thermal objective, daylight camera, inertial unit and the processing computer inside a single housing. All of it drawn, dimensioned and released by our own engineers.
