HXMT Planning and Scheduling Based on Evolution Method

Abstract:

The Hard X-ray Modulation Telescope (HXMT) is an X-ray satellite devoted to a sensitive all-sky survey and to study timing and spectral characteristics of X-ray sources. In this paper, the requirement of planning for the satellite is described at first. And then based on the discussion of the observation requirement and the constraints of planning, an evolution scheduling algorithm is designed. The algorithm is based on NSGA-II. The observe windows of each observation are used as gene to composing a chromosome. The genetic operations, including selection, crossover and mutation, are based on the DNA coding. Results are presented according a test set, and some conclusions and possible improvements will finally be outlined.
