11th BroadSky Workshop “<strong>Small</strong> <strong>Satellite</strong>s, Big Possibilities”<br />
[Launch System Innovation]<br />
Conventional launch vehicles required a significant period <strong>of</strong> time and effort to launch.<br />
Goal <strong>of</strong> <strong>Small</strong> <strong>Satellite</strong> <strong>Program</strong> <strong>of</strong> <strong>ISAS</strong><br />
With the Epsilon Launch Vehicle, launch systems are improved and simplified in order to<br />
reduce time for launch preparation. This will make times to launch the shortest in the<br />
world. Notably, the inspection <strong>of</strong> on-board devices will be done autonomously by the<br />
launch vehicle itself, thus streamlining inspection on the ground. This advance will allow<br />
<br />
<br />
More opportunities the <strong>of</strong> launch scientific control <strong>of</strong> launch vehicles missions<br />
to be done anywhere in the world, simply by<br />

KM-V2b<br />
Third Stage Solid connecting a laptop computer to the network. This means having an ultimate launch<br />
coupling with Epsilon rocket<br />
Motor(KM-V2b) control system which is independent <strong>of</strong> launch sites. We believe that these innovative<br />
concepts are a world first, and will be a role model for future launch vehicles.<br />
