Advanced avionics solutions for uncrewed systems

Callen-Lenz designs and develops avionics and autopilot solutions for a wide range of uncrewed aircraft, from multirotor and rotary wing to fixed-wing, hybrid fixed-wing, hybrid tilt-wing, and experimental platforms. Designed and developed entirely in-house by expert systems and software engineers, our avionics are cyber secure, rugged, reliable, and proven in complex operational environments.

SC3 autopilot and mission management system

The SC3 is the latest generation autopilot and mission management system from Callen-Lenz, engineered to deliver maximum capability with minimal pilot workload.

Explore the core capabilities that make SC3 a trusted, future-ready autopilot and mission management system:

SC3 is designed to work on any uncrewed aircraft, fixed-wing, rotary, hybrid, multi-rotor, enabling you to standardise avionics across diverse UAS fleets.

Built with automotive-grade lock-step processors and model-based control design, SC3 brings reliability and rigorous engineering into UAS operations.

SC3 reduces pilot workload by enabling pre-programmed missions, autonomous operation, crewed-uncrewed teaming (CUC-T) and swarm capabilities - so your team can focus on mission outcomes rather than manual piloting.

With high-speed data logging, a wide range of interface/connectors and support for mission control, navigation and payload management, SC3 keeps you connected and informed.

SC3 has been operationally proven over thousands of flight hours and utilised in complex applications like crewed-uncrewed teaming and tactical deconfliction scenarios.

The design of SC3 anticipates evolving mission profiles from ultra-long-range operations to swarms, providing a scalable avionics framework for tomorrow’s UAS demands.

The SC3 architecture is purpose-built to meet the demands of real-time flight control while supporting mission management, navigation, communication, and data logging across a variety of mission profiles:

  • Standalone autonomous missions
  • Crewed-uncrewed teaming
  • Swarm operations
  • Ultra-long-range deployments

 

With high-speed data logging, a wide range of interface/connectors and support for mission control, navigation and payload management, SC3 keeps you connected and informed.

SC3 integration case studies

Safe flight

Using SC3 technology, Callen-Lenz integrated and flew the Tactical Deconfliction sensor system onto the FW Fregata air frame. The flight trial involved the test aircraft flying towards stationary, dynamic airborne objects and pre-mapped terrain hazards, resulting in the test aircraft detecting these threats and the DARi onboard intelligence system taking steps to send speed, heading and/or altitude override commands to the SC3 Autopilot to avoid and maintain safe operating distances, autonomously.

CUC-T

In September 2020, Callen-Lenz and Leonardo completed a demonstration of Crewed-Uncrewed Teaming (CUC-T) between a 4m wingspan Callen-Lenz Fregata UAS and a crewed AW159 Wildcat Helicopter. The Fregata aircraft and its optical sensor were being operated from an interface within the Wildcat using our own SC3 autopilot and mission management system. A UAS Gateway Processor, supplied and integrated by Callen-Lenz, enabled the Fregata to be operated in line with an onboard sensor and provide the pilots with a live video feed from the Fregata whilst operating the UAS and helicopter with minimal additional workload. This demonstration was part of the Army Warfighting Experiment 19 (AWE19).
