  • ABOUT
  • PUBLICATIONS

Mr. Dimitrijevic has been working in the field of Aerospace electronics for 5 years and general electronics design for 7 years. Most notably, he has developed the instrumentation, power management, and the overall electrical and electronics design of the SCRAMSPACE I experimental hypersonic vehicle. In addition, Mr. Dimitrijevic has developed a number of prototypes of inertial navigation systems, one of which has been flight proven on a real hypersonic vehicle.

CAPABILITIES

  • Design of electronic systems for Aerospace applications
  • Management of manufacture, procurement and assembly of electronic systems
  • Analog instrumentation design
  • High precision data acquisition systems
  • Custom logic design in VHDL for FPGA/PLD devices
  • SPICE simulations
  • Unit testing and environmental testing of electronics for Aerospace applications
  • Low level driver development on bare silicon and Linux systems (in C)

 

EXPERIENCE:

In the last few years, Mr. Dimitrijevic has worked on electronics and instrumentation for hypersonic vehicles. He has developed a full analog signal acquisition electronics for the SCRAMSPACE I hypersonic vehicle including a high precision, low noise data acquisition system driven by an FPGA. He has also developed the high level electrical system architecture on SCRAMSPACE I, power switching and regulation electronics, and has been heavily involved in assembly and ground testing of hypersonic vehicles.

Mr. Dimitrijevic has also developed the hardware and low level drivers for a number of Inertial Navigation Systems (INS) and Attitude and Heading Reference Systems (AHRS). These systems require integration of high level processors such as the ARM Cortex A8, sensitive Inertial Measurement Units (IMUs) and variety of communication protocols.

During his Bachelor degree, Mr. Dimitrijevic developed a motor failure detection system for quad rotor Unmanned Aerial Vehicles (UAVs). The system implements detection and correction algorithms on FPGA hardware that monitor the performance of individual motors and detect motor performance degradation. In case of full in-flight motor failure, the system is able to keep the UAV stable, compensating for the failed motor by driving the opposite motor bi-directionally, allowing the operator to land the vehicle safely.
