Beschreibung
Zusammenfassung:	The invention discloses a satellite emergency measurement and control risk assessment method based on historical data, and the method comprises the steps: firstly obtaining the historical measurement and control data of a satellite and measurement and control equipment, and extracting the parameters of a to-be-executed emergency measurement and control event; comparing the key parameters of the emergency measurement and control event with the hard constraint conditions, and judging whether the event has performability or not; calculating subitem risk index values of the emergency measurement and control event according to the historical measurement and control data and the emergency measurement and control event parameters; determining sub-item risk index weights by adopting a subjective and objective comprehensive weighting method, and calculating a comprehensive risk assessment value of the emergency measurement and control event; and according to the sub-item index value and the comprehensive evaluation va
