BIO

ABOUT ME

I was born in 1980 in Kırıkkale. After Bursa Işıklar Military High School, I graduated from the Turkish Air Force Academy in 2003 as an Electronic Engineer. My undergraduate thesis was "The Use of Electromagnetic Waves in Aviation" on Electromagnetic Waves. After graduation, I joined Izmir Çiğli Air Force Base as a Lieutenant for my pilot training. After flight training in SF-260 and T-37 types, I went to the Air Defense School and graduated as an Intercept Controller in 2005. My first professional duty as a controller was Şarkışla Air Radar Position Command and I worked here between 2005-2009. My next assignment was in Ahlatlıbel Air Radar Position Command in 2009 and until 2013 I served as Intercept Controller, Fighter Allocator Officer and Master Controller. While I was working here, I was sent to BOEING, Seattle, Washington / USA in 2012 to receive mission team training as part of the Peace Eagle project. Between 2013 and 2015, I served as Weapon Controller and Fighter Allocator Officer at the 3rd Main Jet Base 131st Squadron. Later, I was assigned to the 3rd Main Jet, NATO NAEW E3A AWACS Forward Operation Base (FOB). from 2015 until 2017 in Konya / Operations Officer in Turkey, and I served as Deputy Commander of FOB. I also performed additional professional duties such as INFOSEC & CYPER DEFENSE (Information Security and Cyber Defense) Officer, Crypto Officer, COMSEC (Communication Security) Officer and DSO (Department Security Officer). I was honored with the NATO Secretary General's "NATO Meritorious Service Medal". I have successfully completed my master's thesis on "Space Technologies (Satellite Design)" in the Department of Space Sciences at Istanbul Technical University, which I was doing simultaneously while performing my profession. I have my own satellite design project and patent on the lunar mission. At the end of 2017, I started my doctorate program at the Hezarfen Aeronautics and Space Technologies Institute of the National Defense University in Istanbul, where I have been accepted on behalf of the Turkish Air Force. I have studied on Formation and Cluster Satellite Architecture in the Space Sciences Department, Space Sciences Doctorate Program. I have graduated Space Sciences doctorate program in 2021 form Hezarfen Aeronautics and Space Technologies Institute of the National Defense University. I am currently working as the Institute Secretary at the Hezarfen Aeronautical and Space Technologies Institute, where I was appointed in 2020. I have the "International Aviation Federation (FAI) P2 Paragliding Pilot License". I have an (EASA) Private Pilot license (PPL) with night VFR and IFR authorization and completed the "Airline Transport Pilot License (ATPL (A)) Theory". I also have a European (EASA) Commercial Pilot License (CPL (A)) with Multi Engine Ratings (MER).

About The Publication
This paper is devoted to understanding traditional relative navigation and models which are used for small satellites. Compare the traditional relative navigations models and approaches which are based on different systems (Inertial Navigation Systems (INS)&Global Navigation Satellite System (GNSS) , Laser&INS, etc.). These based Technologies are used individually or combined with each other for solving relative navigation problems.  The advantages and disadvantages of models are varied according to usage area, platform type, etc. Different methods and approaches exist besides, need for different estimation and optimization algorithms for adaptation, control, and sensor fusion. All the models are focused on assuming that perfect attitude conditions. Only consider relative navigation and distance perspective. Also, the aim of this article is understanding to the correlation between relative navigation systems and the effectiveness of algorithms use for estimating the states during constellation or formation flight.

GPS Based Fault Tolerant Satellite Localization

Tuncay Yunus ERKEC, Chingiz HAJIYEV
Conferences Selected
About The Publication
This paper is devoted to Global Positioning System (GPS) based satellite localization which is used for the Pseudo-ranging model. The GPS is popular for detecting and estimating satellite position vectors. In this study, the satellite localization was detected via measurement of the actual distance between 4 GPS satellites and the target satellite. The Keplerian equations and orbit elements are used for the satellite dynamic model. J2 orbit perturbation is taken into account within the EKF algorithms. The novel approach is fault-tolerant satellite state estimation which is designed according to 2 versions. One of them is reconfiguration fault-tolerant satellite localization and the other one is adaptively fault-tolerant satellite localization. The Extended Kalman Filter (EKF) is used for satellite state vectors estimation and detection of GPS measurement errors. The Reconfigurable version and the adaptive version of fault-tolerant localization architecture eliminate the GPS measurement errors during estimating satellite orbital position vectors.

Conferences Selected
About The Publication
This article is devoted to the analysis of relative satellite vector estimations with extended Kalman filter (EKF) using the target and follower satellite positioning approach obtained by the Newton Raphson method (NRM). In this study, target and follower satellite baseline values were determined as derived simulation data. Position states due to Earth-centered inertial (ECI) reference frame were obtained by Keplerian orbital parameters and Global Positioning System (GPS) receiver. The Pseudo-ranging model was used to determine the position of target and follower satellites. To simulate GPS receiver, random measurement errors were added to the actual distance between the target and follower satellites. With this study, satellite relative state vectors are obtained within the analysis scenario.

About The Publication
This paper is devoted to Global Positioning System (GPS) based cluster Satellite architecture localization which is used for Pseudo-ranging model. The relative satellite state estimations are detected and estimated by fault-tolerant Kalman filters via measurement of the actual distance between 4 GPS satellites and the target satellite. The Keplerian equations and orbit elements are used for target and follower satellites dynamic models. J2 orbit perturbation is considered within the relative states estimation stage via covariance matrices of target and follower satellites’ localization stages. The novel approach is fault-tolerant relative satellite state estimations which are designed according to 2 versions. One of them is reconfiguration fault-tolerant cluster satellite localization and the other one is adaptively fault-tolerant cluster satellite localization.

Many approaches are used for satellite navigation estimates. Besides the GPS is commonly used for determining a satellite’s orbital state vectors by many researchers. The fault-tolerant state estimation models are used for not only space vehicles but only terrestrial, naval vehicles during motion control and localization problem. In this study, the satellite localization was detected via measurement of the actual distance between 4 GPS satellites and target satellite. The Keplerian equations and orbit elements are used for satellite dynamic model J2 orbit perturbation are taken into account within the EKF algorithms. The novel approach to the fault-tolerant estimation of satellite states which is designed according to 2 versions is proposed. One of them is reconfiguration fault-tolerant satellite localization and the other one is adaptively fault-tolerant satellite localization. The Extended Kalman Filter (EKF) is used for the satellite stat vector estimation and detection of GPS measurement errors. The Reconfigurable version and the adaptive version of fault-tolerant localization architecture eliminate the GPS measurement errors during estimating satellite orbital position vectors. Approaches to identify target satellite state vectors can also be used as a fault warning system feedback within the GPS system.

Journal Paper Selected
About The Publication
This paper means to comprehend vision-based relative navigation strategies which are utilized for small/microsatellites. Advancements dependent on this technique are utilized separately or joined with one another to deal with relative position issues. The benefits and detriments of vision-based relative navigation models change as indicated by space of utilization and stage type. Various strategies and approaches exist and need distinctive assessment and advanced algorithms for variation, control, and sensor combination. Each of the models centering inside expects those ideal disposition conditions. This paper just spotlights on relative route and distance point of view. Additionally, the point of this article is to comprehend the connection between’s general navigation control frameworks and the adequacy of calculation, which are utilized in assessing the states during gathering or development flight/development.

About The Publication
This paper is devoted to understanding relative navigation models that are used for space vehicles. The relative navigations models and approaches are based on different systems (Inertial Navigation Systems (INS)&Global Navigation Satellite System (GNSS), Laser&INS, Vision-Based, etc.) are compared. These models and approaches can be used individually or combined for solving relative navigation problems. The advantages and disadvantages of the models vary according to the usage area, platform type, and environment. Different methods and approaches exist in addition to different estimation and optimization algorithms for adaptation, control, and sensor fusion. Most of the models assume perfect attitude conditions. This study considers satellites’ position estimates according to each other within formation on the Low Earth Orbit (LEO). Also, the aim of this article is to understand the correlation between the relative navigation systems and the effectiveness of the algorithms which are used for estimating states during constellation or formation flight.
