Description

technical field [0001] The invention belongs to the technical field of satellite mission simulation, and in particular relates to a micro-nano satellite energy balance evaluation system and an application method thereof, which are used to evaluate the energy balance state of micro-nano satellites, and are especially suitable for low-orbit micro-nano satellites with complex tasks and frequent and fast maneuvering postures. Assessment of satellite energy balance. Background technique [0002] The energy balance of micro-nano-satellites powered by solar energy is affected by many complex factors, and various factors are coupled with each other. This situation has caused great difficulties in energy balance assessment. [0003] The acquisition of solar energy by micro-nano-satellites is affected by many factors: the orbit of micro-nano-satellites is low, the orbital period is short, and they will frequently switch between the light area and the earth-shadow area during orbital w...
