6th International Workshop on Lean Satellite – December 2023

A “Lean Satellite” is a satellite that utilizes non-traditional, risk-taking development and management approaches – with the aim to provide the values of satellites to the stakeholders at low-cost and in short time to realize the satellite mission. These approaches differ significantly from traditional approaches to satellite development. The term “Lean Satellite” was born during the activities related to the international standardization of small/micro/nano/pico satellite testing starting from 2011. At that time there was no clear definition of the terms “small”, “micro”, “nano”, “pico” that was agreeable to all concerned. To capture the essence of development and management philosophy -- rather than categorizing on the basis of mass or size -- the term “Lean Satellite” was adopted.

Every year since 2011, an international workshop to discuss various aspects of “Lean Satellites” has been organized. This international effort has led to the publication of ISO-19683 “Space systems — Design qualification and acceptance tests of small spacecraft and units” in July, 2017, and ISO-TS-20991 “Space systems -- Requirements for small spacecraft” in August, 2018.

The purpose of 6th workshop in December 2023 is to further promote the study of lean satellites. To deliver the satellites’ value to stakeholders at affordable cost and permissible waiting time, there are various issues to be examined further, such as standards, testing, operation, manufacturing, interfaces, project management, etc. This workshop puts an emphasis on constellations, especially manufacturing and testing of constellations. The number of satellite constellation programs that are made of multiple satellites with an identical or quasi-identical design is increasing drastically. When ISO-19683 was developed in early 2010s, few “Lean Satellite” constellation programs existed. In the past 10 years, however, the landscape has changed dramatically. During this workshop, we want to discuss the state-of-art of constellation manufacturing and testing and other related topics. The result will be incorporated into the revision of ISO-19683 and other “Lean Satellite” related standards.

This workshop intends to serve as an open forum for people interested in making and using satellites differently from the traditional ways. The workshop will be made of the following sessions (please click here for short description of each session),

• Session-1 Satellite design for constellations
• Session-2 Mass manufacturing for constellations
• Session-3 Testing of constellations
• Session-4 Ground segment and operations of constellations
• Session-5 Applications and technologies of Constellations (imaging, sensing, information, navigation, communications, science, AIs, etc.)
• Session-6 Launch of Constellations
• Session-7 Lean Satellite technologies, applications, missions, and concept
• Session-8 Standards
• Session-9 Students and young engineers
