In 2010, Callen-Lenz became a world leader in the breakthrough technology of drone-based photogrammetric data capture. This pioneering remote sensing service uses in-house designed aircraft with modified sensors to fly over forests and crops gathering 3D and multispectral data. Innovation and pioneering technology have been the hallmarks of Callen-Lenz since the start.

Since 2012, Callen-Lenz has pioneered Beyond Visual Line of Sight (BVLOS) testing and evaluation as a commercial operation, supporting trials for the UK MoD and commercial customers. Trials services then grew to encompass regular provision of BVLOS counter-UAS target services and flight testing of large military and commercial UAS.

In 2013, Callen-Lenz acquired SkyCircuits, which became a wholly owned subsidiary of Callen-Lenz. SkyCircuits develops high-integrity autopilots for use in crewed and uncrewed systems. SkyCircuits launched the first autopilot/mission management system, SC2, for use across the civil and defence markets. Since 2013, the SC2 has architecturally evolved, leading to the design and manufacture of the SC3 in 2019, a more powerful and sophisticated autopilot. SkyCircuits has produced hundreds of autopilots since 2013 and is best-in-class, readily tailored and integrated into a wide variety of platform configurations.
