Problems solved by technology
The performance index of the satellite data receiving system covers many aspects. At present, the research on the performance evaluation index of the satellite data receiving system focuses on the analysis and evaluation of the receiving ability index, and lacks a unified evaluation index, especially for the evaluation of the satellite data receiving task planning algorithm. A unified evaluation method has not yet been formed. Various task planning model algorithms are involved in receiving task planning, and each algorithm has a specific scope of application and technical characteristics. The purpose of expanding the algorithm is to be able to conduct a systematic evaluation of the performance and scope of the algorithm, so as to determine how to choose the algorithm in the planning process

Embodiment Construction
[0048] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0049] The invention discloses an efficiency evaluation method of a satellite data receiving system, such as figure 1 shown, including the following steps:
[0050] Step 1: Construct the satellite data receiving system performance evaluation system;
[0051] The constructed performance evaluation index system includes four levels of indexes, such as figure 2As shown, the lowest layer is the first-level indicators of the satellite data receiving system. The first-level indicators are calculated from the corresponding evaluation sample data generated during the satellite data receiving process, including the total task completion rate, important task completion rate, ground station load rate, Ground station utilization, ...
