International Workshop on Lean Satellite – 2020

 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. 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 based on 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 held. The purpose of the workshop is to further promote the study of lean satellites. To deliver the satellite values to stakeholders with affordable cost and permissible delivery time, there are various issues to be examined further, such as standards, testing, operation, manufacturing, interface, project management, etc. Since the beginning of the series, the workshop has focused on standards. It produced two ISO documents, ISO-19683 “Space systems — Design qualification and acceptance tests of small spacecraft and units” and ISO-TS-20991 “Space systems -- Requirements for small spacecraft”. Following the workshop in 2019, this year’s workshop will put an emphasis on CubeSat interface standardization. There is a strong need to standardize the interface not only among CubeSat components but also between a CubeSat platform (bus) and mission payloads to shorten the satellite delivery time and to promote international trade and collaboration.

 This workshop intends to serve as an open forum for people interested in making and using satellites differently from the traditional ways. Due to the current situation surrounding COVID-19, it has been decided unfortunately that the workshop this year will be held virtually. We will have:
