Design and integration

REF has demonstrated experience in the design and manufacture of custom solutions for niche applications and works with clients to elicit requirements to suit end needs. The team has proven capability in the integration of a multitude of sensors on airborne systems to enable researchers to acquire data in a way not previously possible. This includes working to DO178B/C and DO297 standards, as well as with regulatory authorities such as the Civil Aviation Authority (CASA) to ensure seamless certification through the knowledge transfer process.

Examples of this include the design and manufacture of a lightweight two axis gimbal utilizing brushless motors and an Alexmos 32 bit BGC. The aim of the project was to build a custom gimbal to enable stabilization of the Headwall Nano Hyperspectral sensor and keep it within the weight limits of the DJI S800EVO multirotor. It has sophisticated vibration dampening and a wide center of gravity adjustment to ensure correct balance. It utilizes 3D printed and carbon fiber components. Two inertial measurement units (IMUs) are used for the frame and camera.

This equipment is now utilised by both QUT and Kansas State University to augment their data capture efficacy when using the Headwall Nano Hyperspectral sensor.

Other examples include the design and manufacture of an integrated spore trap for bio-data collection – working with the research team to elicit requirements and end needs, this unit has been created for seamless integration onto one of our multi-rotor platforms, taking into account requirements such as undisturbed air intake, centre-of-gravity placement and integration with the RPAS autopilot; as well as the design approval and manufacture of a sensor payload to support research into vertical infrastructure inspection tasks.
