Abstract

The invention provides a micro-nano satellite energy balance evaluation system and an application method thereof. The energy balance evaluation system comprises a satellite flight orbit simulator, a task planning computer, a tested micro-nano satellite, a ground power supply program control machine, a solar array simulator and an energy balance evaluation device. According to the invention, micro-nano satellite energy balance is evaluated based on satellite physical simulation, setting of various parameters in the test process is consistent with the state of a satellite during in-orbit flight,and the energy consumption and supply state of the micro-nano satellite during in-orbit work can be well simulated. The telemetry parameters reflect the influence of satellite attitude and orbit parameters, platform and load working states and other factors on micro-nano satellite energy balance; the energy balance state can be comprehensively and accurately evaluated by analyzing the telemetry parameters, potential risks are eliminated, the satellite energy use efficiency is improved, and the potential of a satellite is developed to the maximum extent.

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...
