5th International Workshop on Lean Satellite - January 2023

A “lean satellite” is a satellite that utilizes non-traditional, risk-taking development and management approaches – with the aim to provide value of some kind to the customer at low-cost and without taking much 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. So 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 this three-day workshop (the fifth workshop since the name settled into the present one) in January 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, interface, project management, etc. This 2023 workshop puts an emphasis on testing for satellite programs with multiple satellites, e.g. constellations. The number of constellation satellite programs that are made of multiple satellites with an identical design is increasing. When ISO-19683 was developed in early 2010s, few lean satellite constellation programs existed. In the past 10 years, however, the landscape has changed rapidly. Currently, ISO-19683 is under systematic review. During this workshop, we want to discuss how the standard should be revised to include the multiple satellite programs and to reflect the knowledge cumulated since the early 2010s.

This workshop intends to serve as an open forum for people interested in making and using satellites differently from the traditional ways. The workshop consists of the following activities

The workshop is organized by Kyushu Institute of Technology (Kyutech) in collaboration with City of Kitakyushu and with the support of the Ministry of Economy, Trade and Industry (METI), Japan.
