AstroSat Proposal Processing System (APPS) is a mission critical software solution designed and developed by the joint efforts of Indian Space Research Organization and the Inter-University Centre for Astronomy and Astrophysics. It facilitates the participation of global scientific community to submit scientific proposals for observations with India’s first multi-wavelength space observatory. The software systematizes the proposal submission and review process before the successful proposed observations are scheduled to carryout scientific observations. This paper describes the overall architecture of the system, implementation stratagems, administrative aspects and security aspects of the software. The paper also describes the techniques adopted for seamless day-to-day operations in meeting the mission requirements. As a future direction, the paper summarizes the roadmap for development of a generic multi-mission proposal handling model from the experiences gained through APPS.

AstroSat Proposal Processing System (APPS) 是一项关键任务软件解决方案，由印度空间研究组织和校际天文和天体物理学中心共同设计和开发。它促进了全球科学界的参与，以提交与印度第一个多波长空间天文台进行观测的科学建议。在成功的提议观测计划进行科学观测之前，该软件将提议提交和审查过程系统化。本文描述了系统的整体架构、实施策略、管理方面和软件的安全方面。该文件还描述了为满足任务要求而在无缝日常操作中采用的技术。作为未来的方向，
