Seven microsatellites were deployed as piggyback payloads to the Ibuki spacecraft. All of these spacecraft will follow a similar roughly 660 km sun-synchronous orbit. Six of the small satellites were developed by universities and private-sector companies; the seventh is a technology demonstrator for JAXA.

SDS 1, the Small Demonstration Satellite 1, is a technology demonstrator mission developed by JAXA. The satellite is approximately 70 x 70 x 60 cm in size and is 100 kg. Solar cells will provide approximately 100 W of power. The spacecraft features a multi-mode integrated transponder. During its mission it will carry out on-orbit verification of a space wire demonstration module, a cutting-edge microprocessor, and a thin-film solar cell.
