Department of Space Systems Design

Introduction

The main objective of Department of Space Systems Design (SSD) is to apply system engineering on development of small satellite systems and advanced space systems. The main research areas of SSD consist of design and system management, launch service and procedure management, small satellite constellation design, training activity, and spinoff technology development.

 Members

Currently, The SSD has a team of ten members who are working in four areas including system engineering, launch service, procedure management, system integration, and spinoff technology development.

Research Areas

The main research areas of SSD are described as follows:

1. System Design

  • Mission analysis
  • Technical requirement definition
  • Design, simulation and technical solutions
  • System architecture

This research area will focus on mission analysis to define system requirements and sub-system requirements of satellite. Based on those requirements, the system design, simulation, and technical solutions will be proposed and evaluated. The system design will be eventually decided to process for manufacturing and assembling in next steps.

2. System Integration

  • System/subsystem integrations
  • Evaluation and verification

Based on system design and subsystem requirements, the techniques for fabrication and integration will be chosen. After this step, the evaluation and verification will be implemented.

3. Launch Service and Procedure Management

  • Procedure management
  • Launch service

In this area, the SSD takes management responsibilities in implementation of satellite development projects in Vietnam National Satellite Center (VNSC). The SSD will be in charge to manage satellite projects that are required to meet the requirements such as quality, safety and time. In addition, the SSD team will be an important role in execution of the management standards to satellite projects in VNSC.

4. Training Activities

The SSD will take part in training and international collaboration activities at university levels to support for human resources development in Vietnam. Currently, The SSD team is participating in several training programs in two Vietnamese universities that are listed as follows:

  • Undergraduate training program of Aerospace Engineering at The University of Engineering and Technology – Vietnam National University
  • Undergraduate and Graduate training programs of Space and Aeronautics at The University of Science and Technology of Hanoi

5. Spinoff Technology Development

The SSD also aims at researching and developing spinoff technologies toward applying space technology for the society.

6. Small Satellite Constellation

Due to the demand of applications, small satellite constellation is a new trend in space industry. The SSD team will study and evaluate the feasibility in development of small satellite constellations in Vietnam.
