Predator drone with stabilized gimbal optical payload

Practical Precision specializes in engineering lightweight and rugged high-performance optical systems for aerospace, defense, and security applications, including stabilized gimbals and payloads; hand-held imagers and targeting systems; weapon sights; and space based systems.

More capability in a smaller package

Deliver more capability in a smaller package to your customers by leveraging our experience and expertise in developing multi-sensor systems and payloads that retain boresight alignment under harsh operating conditions, handle higher thermal densities with less space and surface area for cooling, and yet remain manufacturable and serviceable.

Engineered to perform after drops, weapon shock, or space launch

Your product will be engineered to perform even after drops, weapon shock, or space launch – while meeting weight budget – through analysis-driven design, weight-optimized system architecture, and the application of high-performance, lightweight materials (including plastics, carbon fiber, beryllium alloys, and silicon carbide) in the optimum form, function, and combination.

A US small business serving the aerospace and defense community

Practical Precision is a US small business providing engineering services to aerospace and defense companies including Northrop Grumman, General Dynamics, and FLIR. Many of the projects we work on are covered by ITAR.

Our focus is engineering lightweight and rugged high-performance optical systems that are optimized for harsh service environments, including space, high-altitude, and the combat theater, including sea, air, and land. These systems range in size and operational mode from handheld to weapon mounted to man-portable to manned or unmanned craft-mounted to Earth- and space-based telescopes.
