AstroSat is an astronomical observatory from India which is in a low earth orbit of 650 km altitude with a 6-degree inclination and has been functioning successfully in orbit for the last 5 years. The simultaneous observation by the payloads allows imaging of celestial sources in various wavebands that has resulted in scientific achievements which are published in various forum. Uniqueness of its orbit, and scientific objectives calls for a different type of scheduling approach and a hands-free automated tasking of payloads, on this satellite. Several software architectures involving a Centralized data-base called Mission Control And Proposals (MCAP) with the Scheduler, AstroSat Scheduler TeRminus for PAyLoads (ASTRAL), AstroSat Scheduler Software for OpeRaTions (ASSORT), Command Sequence Generation (CSG), AstroSat Schedule Viewer (ASV), Astroviewer and AstroSat Long Term Planner (ASPlanner) were developed and used for celestial source observations. This paper describes briefly the scheduling approaches, their goals, utilization, lessons learnt and improvements carried out over the last 5 years.

AstroSat 是一个来自印度的天文台，位于 650 公里高度、6 度倾角的低地球轨道上，过去 5 年一直在轨道上成功运行。有效载荷的同时观测允许对不同波段的天体进行成像，从而产生了在各种论坛上发表的科学成就。其轨道的独特性和科学目标要求在这颗卫星上采用不同类型的调度方法和有效载荷的免提自动任务。几种软件架构涉及称为任务控制和建议 (MCAP) 的集中式数据库和调度程序、AstroSat 调度程序终端用于 PAyLoads (ASTRAL)、AstroSat Scheduler Software for OpeRaTions (ASSORT)、命令序列生成 (CSG)、AstroSat Schedule Viewer ( ASV），Astroviewer 和 AstroSat Long Term Planner (ASPlanner) 被开发并用于天源观测。本文简要描述了过去 5 年中的调度方法、它们的目标、利用、经验教训和改进。
