Research Areas research areas


research overview

  • Dr. Akos' research is focused on satellite navigation receivers for the US Global Positioning System (GPS), Russia‚Äôs GLONASS, China's Compass, and Europe's Galileo Global Satellite Navigation Systems as well as the various regional systems and augmentations. His investigation focuses on all aspects of the satellite navigation receiver: the antenna, through the radio front end, and the internal signal processing as well as the position solution. This includes such topics as enhanced sensitivity, improved antenna design/antenna arrays, and radio frequency interference detection and mitigation - all to increase robustness. Dr. Akos pioneered the concept of the 'Software Radio' for GPS and other satellite navigation system, providing insight necessary to use such equipment for safety-of-life operations such as aviation. In addition, his expertise with the receiver architecture has been employed in a number of unique aspects, now using the suite of Global Navigation Satellite System (GNSS) signals for remote sensing and other diverse applications.

selected publications


courses taught

  • ASEN 3300 - Aerospace Electronics and Communications
    Primary Instructor - Spring 2022 / Spring 2023 / Spring 2024
    Provides the fundamentals of electronics and communications widely used in aerospace engineering. Includes analog instrumentation electronics, data acquisition, digital electronics and radio communication.
  • ASEN 4018 - Senior Projects 1: Design Synthesis
    Primary Instructor - Fall 2018 / Fall 2020 / Fall 2021
    Focuses on the synthesis of technical knowledge, project management, design process, leadership, and communications within a team environment. Students progress through the design process beginning with requirements development, then preliminary design and culminating with critical design. Offered fall only.
  • ASEN 4028 - Senior Projects 2: Design Practicum
    Primary Instructor - Spring 2019 / Spring 2021 / Spring 2022
    Focuses on the fabrication, integration, verification and validation of designs produced in ASEN 4018. Students work within the same teams from ASEN 4018. Offered spring only.
  • ASEN 6091 - Global Navigation Satellite System (GNSS) Receiver Architecture
    Primary Instructor - Spring 2021 / Fall 2022 / Fall 2023
    Investigates the overall architecture of satellite navigation receivers: including both the analog radio frequency conditioning (antenna to the analog-to-digital converter) and the various signal processing algorithms. Such treatment of the operation of the receiver will provide insight into the trade-offs that go into GNSS as well as the more broad generic spread spectrum receiver design. Recommended prerequisite: ASEN 5090.
  • ECEN 5014 - Special Topics
    Primary Instructor - Fall 2023
    Examines a special topic in Electrical, Computer and Energy Engineering. May be repeated up to 9 total credit hours.
