APOSOS Project was originally proposed by China, Peru and Turkey in 2008, and the feasibility study of this project was approved during the First Meeting of the Council in 2008. In 2009, the Second Meeting of the Council decided that the leading countries for APOSOS were China and Turkey. China and Turkey would initiate the draft feasibility study and circulate among Member States. In the Fourth Meeting of the Council, the Council approved the Feasibility Study of the First Stage of APOSOS as a basic activity. It was mentioned in the Working Report of the Secretary-General that the first stage of establishing the data centre and the network would be co-designed with the data sharing platform, and the experimental observation would be carried out by using existing infrastructures from Member States.

The project aims to develop a unified space observation network based on optical trackers in APSCO Member States. The basic objective is to build the network with existing facilities, with the aim of tracking objects and space debris in Low Earth Obit (LEO). The optional objective is to bring new facilities, and extends the ability to track objects and space debris in Medium Earth Orbit (MEO) and Geostationary Earth Orbit (GEO), for peaceful purposes. The network is for the purpose of establishing the infrastructure for a collision avoidance early warning service in the future.

Following are the major events related to this project:
1 The First Meeting for APOSOS Project
The First meeting on APOSOS Project was held on 13 April 2010 in Beijing, China. Around 10 experts from Bangladesh, China, Iran, Mongolia, Pakistan, Thailand and Turkey attended the meeting.

(i) Introduction of Existing Facilities and User Requirements
(ii) Feasibility Study Organization and Plan

At the end of the meeting, all participants agreed that further discussions would be carried out in the next experts meeting to focus on the project definition and implementation.

2 The Second Meeting on the Feasibility Study for  APOSOS Project
The Second Meeting on the Feasibility Study for APOSOS Project was held from 26 to 28 May 2010 at Ankara, Turkey. Around 10 experts from Member States and Non-Member States attended the meeting.
The meeting was organized in eight sessions:

(i)Presentation on Satellite Tracking System

(ii)Presentation on Existing Infrastructure & User Requirement

(iii)Objective Definition and Purpose/Benefit of the Project

(iv)Discussion on Network Establishment & Data Sharing Mechanism

(v)Presentation on System and Architecture Definition

(vi)Discussion on System and Architecture Definition

(vii)Discussion on Software Development

(viii)Cost Analysis and the Implementation Plan

At the end of the meeting, all agreed that the objective of this project had been agreed and confirmed. The experts from the Lead Countries would draft a Feasibility Study Report based on the discussions in the meeting and this report would be circulated among the Member States and Interested Countries for feedback and finalization.
