Prior to Dark's discontinuation, my role included: - Electronic PCB design of avionics for HADES spacecraft - Design and testing of engine ignition systems for 1N, 5N and 20N green thrusters - Architectural design of spacecraft avionics systems

Key Roles and Responsibilities include: - Responsible Design Engineer and hardware owner for key Neutron launch vehicle hardware, including engine controller. Piloting projects from concept through to survival testing - Design, review and validation of Avionics hardware for use on the Neutron launch vehicle

Key Roles and Responsibilities include: - Design, review and validation of Avionics hardware for use on the Electron launch vehicle and third-party vehicles - Management and maintenance of ECAD project and component libraries - Management of Avionics Component Development Lab

Exploration, design, and development of a UAV mapping system to aid navigation and fleet management of the SeedSpider robot.

Exploration, development and evaluation of different motor encoder technologies for development and production applications. This involved extensive use of LabVIEW FPGA for deployment on NI cRIO hardware, as well as the use of Altium Designer for the design of interfacing hardware.

My main tasks and duties included: - Assembly, preparation and assistance with fabrication of metalwork and components in the workshop - Assistance with aerial rigging work - Installation, configuration and maintenance of radios and other equipment, buildings and machinery as well as hilltop sites and control rooms - Stock and inventory control including ordering, pricing and locating project items

Self-proposed Master's research project for sponsor company Salcom Ltd, enabled through a Callaghan R&D Fellowship Grant. This research project aimed to investigate the applicability of a UAV-mounted cellular femtocell for Search and Rescue purposes. This project involved: - Design and build of UAV platform - Custom antenna gimbal design - Software Defined Radio design with custom FPGA images for use in srsRAN - Design of novel UAV tracking antenna to maintain high-speed eNB to EPC link - Extensive antenna simulation in Ansys HFSS - Simulation and validation of dynamic coverage patterns from aerial femtocell The results from this research were favorable and warrant further development of the system. To date, the research has resulted in 2 publications.
