The deployment of globally distributed telescopes at geographic locations of different longitudes enables the periodic monitoring of transients through relay observation. However, the simultaneous relay observation of numerous targets requires a telescope array of multiple telescopes that can be efficiently coordinated, and an automated scheduler for the array. This paper proposes IPROS, an integer programming model relay observation scheduler for a telescope array, that accounts for the entire process of relay observation and is consistent with the practical scenarios. We introduce the integer programming mathematical model for the relay observation scheduling problem with the telescope array, upon which the scheduler is based. Additionally, we propose an algorithm to provide a comprehensive formulation of the optimization objective of minimizing cadence deviation in the model. Experimental results demonstrate that the relay observation scheduler based on the integer programming model can effectively address the telescope array relay observation problem. It shows superiority over a scheduler with non-specific consideration of relay observation in the modeling and a scheduler based on greedy thought. 分类： 天文学 >> 天文学 期刊： Research in Astronomy and Astrophysics 投稿状态： 已在期刊出版 引用： ChinaXiv:202502.00295 (或此版本 ChinaXiv:202502.00295V1 ) DOI:https://doi.org/10.1088/1674-4527/ad9429 CSTR:32003.36.ChinaXiv.202502.00295 推荐引用方式： Junhan Ju, Ce Yu, Yi Hu, Yajie Zhang, Chao Sun and Jizeng Wei.Relay Observation Scheduling of Global Distributed Telescope Array Based on Integer Programming.Research in Astronomy and Astrophysics:https://chinaxiv.org/abs/202502.00295.[ChinaXiv:202502.00295V1] 版本历史 [V1] 2025-02-25 10:58:35 ChinaXiv:202502.00295V1 下载全文
