Determination of spacecraft inertial properties

A computing device comprising a processor configured to carry out a method of determining one or more inertial properties of a spacecraft, the method comprising:

• receiving data collected at different points in time during operation of the spacecraft, the data including information indicative of:
• the angular momentum of a reaction wheel on-board the spacecraft, and
• the angular velocity of the spacecraft;
• identifying changes in the angular velocity of the spacecraft based on the information indicative of the angular velocity of the spacecraft;
• and
• determining one or more inertial properties of the spacecraft based on the identified changes in the angular velocity of the spacecraft and the information indicative of the angular momentum of the reaction wheel.
