The invention discloses a control method for a continuous observation target of a large-scale heterogeneous constellation. The method comprises the following steps: setting an influence factor which influences the earned value of the observation target; performing weighted assignment on the grids, and generating a demand list according to the assignment; establishing a large-scale constellation to obtain an observation task order grabbing score mechanism; each satellite carries out data processing and target extraction tasks on orbit; surrounding an observation target, carrying out multi-satellite regional networking association fusion on the regional star group according to inter-satellite interconnection conditions; performing motion track prediction of the target on the satellite; and other satellite nodes restart regional planning according to the predicted position after the delta t time, and rescheduling satellites meeting conditions to carry out secondary target observation and tracking. According to the method, parallel computing of massive nodes is supported, and the decision-making efficiency of autonomous planning of satellite observation tasks is improved; under the condition that the inter-satellite link is smooth, the proxy module is supported to be added to the heterogeneous satellite constellation, so that multiple types of satellite constellations can be interconnected and intercommunicated.
