Integration of Non-Stationary Optimal Control Systems with Delay and an Unstable Spectrum Petro Samusenko ORCID: https://orcid.org/0000-0002-4241-6173 National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute” Tetiana Novik ORCID: https://orcid.org/0009-0003-3146-6292 National Aviation University Mykola Rashevskyi ORCID: https://orcid.org/0000-0003-1136-2691 National Aviation University Purpose. We considered a non-stationary optimal control system with delay. Non-stationary optimal control systems are described by systems of differential or differential-algebraic equations. Variable coefficients do not allow, in general, to construct a solution to such systems in quadratures. Numerical …

Review of GPS-Free Navigation Methods for Unmanned Aerial Vehicles Oleksandr Taran ORCID: https://orcid.org/0009-0009-3744-9155 Oles Honchar Dnipro National University Purpose. This paper reviews various non-GPS navigation methods for Unmanned Aerial Vehicles (UAVs), with a particular focus on radio frequency (RF) techniques such as Time of Flight (TOF), Received Signal Strength Indicator (RSSI), and Time Difference of Arrival (TDOA). Design / Method / Approach. The study compares time-based and signal strength-based approaches for locating mobile UAVs, emphasizing the accuracy of multilateration and …

Selection of Launch Vehicle Motion Model Parameters for Spacecraft Insertion into Circular Orbits Ruslan Keba ORCID: https://orcid.org/0009-0007-9490-1254 Oles Honchar Dnipro National University Anatolii Kulabukhov ORCID: https://orcid.org/0000-0003-1139-4829 Oles Honchar Dnipro National University Purpose. This study aims to justify the selection of parameters for a launch vehicle’s pitch angle program during the insertion of spacecraft into circular orbits. The goal is to improve the accuracy and efficiency of the insertion process, optimizing the delivery of payloads to their target orbits. Design / …
