Embodiment Construction
[0049] Further description will be made below in conjunction with specific embodiments. The satellites studied by the present invention belong to resource detection satellites. The historical telemetry data from June to July 2015 were selected for research. During this period, a total of 114 missions were performed. Before the project analysis, it is necessary to use the relevant satellite in-orbit description files. The relationship between the satellite task execution mode and the load is shown in Table 1. In this embodiment, the satellite payload includes a three-line array camera, a multispectral camera, a laser range finder (carrying), a data transmission subsystem, a data transmission antenna subsystem, and a data transmission subsystem. record subsystem. Among them, since the laser rangefinder is a carried load and is always working, it is not considered as a payload. Therefore, the task type M=5 studied in this embodiment.

The invention discloses a satellite efficient load power consumption analysis method based on reuse decomposition. The satellite efficient load power consumption analysis method based on reuse decomposition comprises the steps of: (1), obtaining state parameters of efficient loads when a satellite executes a task; (2), establishing a satellite platform sustained conventional load energy consumption model; (3), calculating energy consumption generated by working of the efficient loads when the satellite executes the task; (4), establishing an efficient load energy consumption reuse model of a single-type task; (5), establishing and solving an efficient load energy consumption reuse decomposition model of a multiple-type task; and (6), calculating the total real-time power of the efficient loads when the task is executed according to real-time telemetry data when the satellite executes the task i. The satellite efficient load power consumption analysis method based on reuse decompositiondisclosed by the invention has the advantage that: the real-time power of the efficient loads of the satellite can be calculated reasonably and accurately by analyzing satellite telemetry historicaldata and not increasing a physical part.
Description
technical field [0001] The invention relates to a satellite payload power consumption analysis method based on multiplexing decomposition, which belongs to the field of satellite measurement and control. Background technique [0002] Satellite payloads are instruments, equipment or subsystems that directly perform specific satellite missions. Satellites carry different payloads due to their different functions. For example, the payloads of the return satellite return capsule include multispectral scanners, infrared scanners, synthetic aperture radars, microwave radiometers, microwave scatterometers, radar altimeters, ultra- Spectral imager and remote sensing information equipment. With the continuous development of aerospace technology, satellite mission planning and health management are gradually becoming more refined and intelligent. Due to the particularity of the satellite's working environment, its limited energy reserve has become a key constraint factor for satelli...
