Abstract

This paper presents a simulation workflow that couples a Keplerian orbit propagator and the World Magnetic Model to generate along-track magnetic-field predictions for typical CubeSat LEO missions. The satellite position estimation mechanism was validated against International GNSS Service reference data, demonstrating acceptable day-scale accuracy that’s fit for attitude determination and control system (ADCS) studies. The synthesized geomagnetic environment shows field magnitudes spanning 18.3-51.7 µT (mean 36.2 µT) and rate of change up to 115.4 nT/s, which directly informs magnetometer dynamic-range and sampling requirements. Using measured PolyITAN-12U coil parameters and the spacecraft inertia, those conditions were translated into magnetorquer performance: torques about 2.3×10⁻⁵ yield angular accelerations of a few ×10⁻⁵ rad/s² depending on axis and local field strength. The workflow thus provides a quantitatively grounded basis for planning Helmholtz cage hardware-in-the-loop tests and tuning ADCS controllers for PolyITAN-12U satellite.
