The on-orbit mission analysis of OTV based on DoDAF

Purpose The purpose of this paper is to improve the efficiency of on-orbit operations through the top-level task design based on DoDAF. Based on the existing upper stage rocket technology, orbit transfer vehicles (OTVs) have developed rapidly in recent years. However, the lack of decision guidance based on overall task analysis requires integrating top-level analysis and bottom-level execution to achieve the smooth development of full-process tasks. Design/methodology/approach Using the Department of Defense Architecture Framework (DoDAF) as a reference, this paper performs the top-level mission analysis modeling of the on-orbit rendezvous and capture of the OTV. Moreover, the typical operational view products are obtained, and the cooperative relations among the mission requirements, the system requirements, and the functional requirements are also analyzed. Findings The results show that the attitude of the OTV changes violently during the maneuver and rendezvous phases. In addition, the view products can be optimized based on the results. Originality/value The proposed DoDAF-based on-orbit task integration analysis method achieves the effective fusion of high-level analysis and bottom-level execution of OTV on-orbit rendezvous and capture task through the top-level task modeling, operation view generation and task relationship analysis. According to the requirements and constraints of the on-orbit rendezvous and capture task, the control instructions of the vehicle are efficiently generated under the DoDAF framework.

THE IMPORTANCE OF MISSION ANALYSIS IN MODERN MILITARY OPERATIONS

The complexity of today’s operational environment has a direct impact on the military instrument of power of every nation. Nowadays, conflicts have a much bigger unconventional component. This component lies in the types of actors involved and the methods used by them. Most contemporary conflicts are no longer classic confrontations between two states that use their military constituent to impose their will on the adversary. Today, the other instruments of power play an equally important role. The resolution of today's conflicts does not only require a military approach to the problem, which further complicates the mission of the military forces, as they are forced to focus on other areas outside the military. Today, non-state actors play a much more important role in armed conflicts. They often fail to comply with international conventions on armed conflict and use any means available to achieve their own goals. In addition, the unprecedented technological development of society in general, but also the unrestricted access to these types of technologies further facilitates the use of unconventional methods by malicious non-state actors in support of their own interests. Therefore, it can be seen that, nowadays, the complexity of armed conflicts has increased exponentially, and the identification and understanding of the problem, the causes of conflicts, as well as the ways to resolve it have become increasingly difficult to achieve. In this regard, I believe that the military should develop appropriate procedures to support the correct understanding of what needs to be done to achieve success and to insist on optimizing the mission analysis as part of the military operations planning process, analysis that should develop the correct understanding of the situation and should support viable future options to solve the conflict.

India’s National Smart City Mission: Analysis of Project Dimensions Including Sources of Funding

The term smart city is defined, and based on India's National Smart City Mission, it is explained what an emerging country can do to start making its cities smarter. Thereby the goals and the program's implementation are analyzed, how it works, and how cities can participate. Moreover, Bhubaneswar and Pune are investigated regarding their smart city plans, goals, and first outcomes. Furthermore, challenges the program faced until now are mentioned and learnings for other emerging market cities on what went well in India and on what does not yet work out that well in the program.
