RAPIS-1 (RAPid Innovative payload demonstration Satellite 1) is a satellite launched on 18 January 2019[3] which for over a year was used to test seven technology demonstration projects. RAPIS-1 was developed and operated by Axelspace Corporation, under the coordination of the Japanese space agency JAXA.[4]

RAPIS-1 was the main satellite of the Innovative Satellite Technology Demonstration-1 mission. RAPIS-1 demonstrated various projects attached to it as either parts or components. The call for proposals for this mission was announced in 2015, and selection results were announced in February 2016.[5] Of the 13 projects selected for Innovative Satellite Technology Demonstration-1, 7 were on board RAPIS-1. A total of eight projects was initially selected, but a proposal by IHI Corporation, the "Demonstration experiment of a innovative ship information receiving system"[5] was later dropped, making the number of projects sent to space on board RAPIS-1 seven. Along with testing the seven projects, RAPIS-1's satellite system also was tested as part of the overall mission. RAPIS-1was developed by Axelspace Corporation, a startup company focusing on small satellite development and application, and is the largest satellite to date the company developed.[4] According to reports by Japanese media, RAPIS-1 was the first case for JAXA to contract a private company to manage the entirety of a satellite, from its development to its operation.[6]
