Ginrei or ShindaiSat was a 400x400x450mm cube-like microsatellite intended to text experimental visible light communication. The satellite is made in Shinshu University (Japan). The ground station was completed by 18 March 2014 and attempts to communicate with satellite have started the same day. 2-way optical communication with ground station is planned. Also, advanced attitude control using visible light communication is planned as well.

Shinshu University Higher education institution in Nagano Prefecture, Japan

Shinshu University, abbreviated to Shindai (信大), is a Japanese national university in Nagano Prefecture, Japan. The only university of its established time, bearing the name "Shinshu" used before the 1871 establishment of prefectural name, is also firmly rooted in the many regions of Nagano Prefecture. It was the 18th ranked higher education institution in Japan.

Mission results

The Ginrei optical signals were received 10 seconds per pass, averaged over 56 passes over the control station. [3] The narrow beam and infrequent operation of optical transmitter have resulted in severe disappointment in amateur optical tracking community. [4]

OPS 0855 American boilerplate Manned Orbital Laboratory spacecraft

OPS 0855, also designated OV4-3, was an American boilerplate Manned Orbiting Laboratory spacecraft launched in 1966. It was flown to demonstrate the launch configuration for future MOL missions. A number of research payloads, designated Manifold, were carried on board, which were intended to operate for 75 days. However, the spacecraft ceased operations after just 30. It was built from a decommissioned HGM-25A Titan I first stage oxidizer tank, bolted to a Transtage. It was part of the MOL and Orbiting Vehicle projects.

TeikyoSat-3 was a technology demonstrator and microbiology microsatellite intended to research the slime mold life cycle in space. Specifically, the effects of ionizing radiation are or special concern. The primary mission is expected to be finished in 10–20 days with completion of first life cycle of slime mold in space, but mission can be extended to study evolutionary adaptations for a maximum of 1 year. Also, a novel thermal control system capable of keeping a stable temperature in small (20 kg) microsatellite bus is being tested. The satellite is made in Teikyo University (Japan) and has a size of 320x320x370mm. The microsatellite microbiology experimental platform is intended to address issues with cost and uncertain future of experiments based on International Space Station. TeikyoSat-3 also transmit its telemetry uncoded at 473.45 MHz, and any amateur radio operator is welcome to share downlink data.

ITF-1, also known as Yui, was an amateur radio cubesat built by Tsukuba University of Japan.

Advanced Land Observing Satellite 2, also called Daichi 2, is a 2-ton Japanese satellite launched in 2014. Although the predecessor ALOS satellite had featured 2 optical cameras in addition to 1.2 GHz (L-band) radar, ALOS-2 had optical cameras removed to simplify construction and reduce costs. The PALSAR-2 radar is a significant upgrade of the PALSAR radar, allowing higher-resolution spotlight modes in addition to the 10m resolution survey mode inherited from the ALOS spacecraft. Also, the SPAISE2 automatic ship identification system and the Compact Infra Red Camera (CIRC) will provide supplementary data about sea-going ships and provide early warnings of missile launches.
