Innovative Satellite Technology Demonstration-1 was the first mission in the Innovative Satellite Technology Demonstration Program. The mission included several spacecraft, the largest being
RAPIS-1, along with six smaller satellites. The call for proposals was announced in 2015, and selection results were announced in February 2016. A total of 14 projects were selected; however a proposal by
IHI Corporation, the "Demonstration experiment of an innovative ship information receiving system" Payloads flown on the mission were tested in space for a year, and the operational data gained were given to the developers. The Innovative Satellite Technology Demonstration-1 marked the first multi-satellite launch by
Epsilon launch vehicle.
RAPIS-1 RAPIS-1 (RAPid Innovative payload demonstration Satellite 1) is a satellite within Innovative Satellite Technology Demonstration-1 that demonstrated selected projects as either parts or components. Of the 13 projects, 7 were demonstrated on board RAPIS-1.
Payload on RAPIS-1 • The NanoBridge based Field Programmable Gate Array (NBFPGA) was developed by
NEC Corporation • High data rate
X-band Transmitter (HXTX) / X-band Middle Gain Antenna (XMGA) was developed by
Keio University • The Green Propellant Reaction Control System (GPRCS) was developed by
Japan Space Systems • The Space Particle Monitor (SPM) was developed by Japan Space Systems • The Deep Learning Attitude Sensor (DLAS) was developed by
Tokyo Institute of Technology • The Thin Membrane Solar Array Paddle (TMSAP) was developed by JAXA • Fireant (Miniature Spaceborne GNSS Receiver) was developed by
Chubu University MicroDragon MicroDragon is a
microsatellite proposal submitted by Takashi Maeno of
Keio University. RISESAT was selected for the Innovative Satellite Technology Demonstration Program to demonstrate highly precise attitude control and high resolution multispectral observation technology. RISESAT's high resolution multispectral camera was capable of measuring the growth rate and health of crops from space. RISESAT's
remote sensing instrument, High Precision Telescope (HPT) utilizes a
liquid crystal tunable filter. RISESAT decayed from orbit on 14 March 2023.
ALE-1 ALE-1, also known as ALEe, was a microsatellite for demonstrating the creation of artificial
shooting stars. Built and operated by
ALE Co., Ltd., it was the company's first satellite. ALE-1 was equipped with a DOM2500
deorbit mechanism manufactured by Nakashimada Engineering Works, Ltd. The DOM2500 was a membrane sail large when deployed, and was used by ALE-1 to lower its altitude to less than , the optimal altitude to conduct its main mission. Once the satellite's altitude was sufficiently lowered, the DOM2500 was separated from ALE-1. The DOM2500 reentered the atmosphere on 3 August 2022, and ALE-1 is expected to re-enter the atmosphere in October 2023.
OrigamiSat-1 OrigamiSat-1 (COSPAR 2019-003B, SATCAT 43933) was a 3U
CubeSat developed by
Tokyo Institute of Technology to demonstrate the deployment of large structures from a small, folded state. After being launched to an altitude of , OrigamiSat-1 was designed to descend down to , where it would deploy a 1m2 membrane. The satellite decayed from orbit on 30 April 2022.
Aoba VELOX-IV Aoba VELOX-IV was a 2U CubeSat equipped with a low-light camera. It was jointly developed by
Kyushu Institute of Technology in Japan and
Nanyang Technological University (NTU) of
Singapore. The pulsed plasma thrusters developed by NTU gave the CubeSat maneuvering capabilities, a necessity for a future lunar mission, as the Moon's
irregular gravity field requires orbiters to perform orbit maintenance to extend its mission lifetime. It had a design lifetime of 12 months in low Earth orbit. The satellite decayed from orbit on 24 March 2023.
NEXUS NEXUS, short for NExt generation X Unique Satellite is a 1U CubeSat developed by
Nihon University. An
amateur radio satellite, it is equipped with a transmitter with half the power consumption and a data transmission rate per second 32 times larger than a traditional amateur radio transmitter. NEXUS will demonstrate
packet radio in space. The satellite decayed from orbit on 9 November 2023. ==Innovative Satellite Technology Demonstration-2==
