Attitude Determination and Control System Open-Source Simulator of a 1U CubeSat Nanosatellite. In 26th International Carpathian Control Conference, ICCC 2025. Stary Smokovec:IEEE. p. 1-6. ISBN 979-833150127-3979-833150127-3http://hdl.handle.net/10198/36085This work developed an open-source educational simulator to evaluate control schemes for small CubeSat-class satellites of 1U size (1 unit). Attitude (orientation) estimation was achieved using the Three-Axis Attitude Determination (TRIAD) algorithm, commonly employed in competitions and real-world CubeSats. A simple Proportional (P) controller was designed to regulate the CubeSat's angular velocity. Additionally, for pointing control (line-of-sight orientation), a Proportional-Derivative (PD) controller was implemented. Numerical simulations were conducted to assess the performance of the CubeSat's Attitude Determination and Control Subsystem (ADCS).engCubeSatTRIAD AlgorithmModified PD controllerAttitude determinationOpen-Source softwareconference paper2026-03-1110.1109/iccc65605.2025.110229532-s2.0-105008986391
