Aerodrag is a dominant force acting on spacecraft operating in Very Low Earth orbit (VLEO). Accurately measuring aerodrag is essential for precise orbit determination and orbit control, consequently, precise attitude determination, better collision avoidance, and longer life missions. Conventional methods for aerodrag estimation rely on GNSS measurements with simplified onboard models, which can be unreliable or inaccurate due to environmental factors, such as atmospheric disturbances or ionospheric scintillation. This study employes Pressure / Force sensors, Temperature Sensors, and mass spectrometers to estimate density / aerodrag. The activity performed simulation of the suitability of these sensors and make a proposal for future work.
