CUTE-I by Tokyo Institute of Technology, Japan
“Our Titech CubeSat project is coded "CUTE" (CUbical
Titech Engineering satellite) project. "CUTE" also means
our CubeSat is cute!”
•Mission: Test platform based on COTS components.
•Camera used as sun sensor

•Had deployable solar panels, and a magnetometer mounted on a 60 cm boom
•The s/c was designed using COTS components.
•Designed for 6 months, it worked flawlessly until at least June 6th, 2004 (more than
11 months)
•Now is still working nominally
From 1st Batch
CUTE 1.7 + APD by Tokyo Institute of Technology, Japan

Single launched double CubeSat (Feb 22nd 2006)
Test of charged particle detector (Avalance Photo
Diode sensor module), made by Tokyo Institute of
Technology.
Due to low perigee (about 300 km at launch)
expected lifetime is significantly less than one
year
Nominal operations. Had some problems in early
March 2006, it was since fully recovered, but
since April 2006 no longer responds to commands
from the ground.

Electric power transmission via structure
From failed launch
• ION by University of Illionis, USA
– Features a Photomultiplier Tube (PMT) to
observe airglow phenomenon in the earth's upper
atmosphere (mesosphere). Also has a low-thrust,
electric propulsion system and a CMOS camera
for Earth imaging.
• RINCON 1 by University of Arizona, USA
– The payload is a low-power beacon system,
which provides a redundant means of relaying
sensor data in analog form if the primary (digital)
transmitter fails.
From failed launch (cont.)
• AeroCube-1 by the Aerospace Corporation,
USA
– Short life satellite (10 days), using Lithium batteries as
primary batteries (no recharging). Mission is to test a
communication system and the system bus plus a suite
of CMOS cameras done by Harvey Mudd College. The
satellite has no deployables. Instead an omnidirectional
patch antenna is used.
• CP2 by California Polytechnic Institute, USA
– Energy Dissipation Experiment
• Sacred by University of Arizona, USA
– measure the total amount of high-energy radiation over a twoyear span and will test the radiation properties of four
commercial integrated circuits
• KUTEsat Pathfinder by University of Kansas, USA
– Measure the radiation in LEO and take photographs with an
onboard camera
• MEROPE by Montana State University, USA
– Radiation experiment (no more information about it on
website…)?
• ICE Cube 1 and 2 by Cornell University (New York
state), USA
– Perform GPS scintillation science by measuring fluctuations in
the signals that the GPS satellites emit when the signals pass
through the ionosphere. Identical to ICE Cube 2
• SEEDS by Nihon University, Japan
– Contains a gyro sensor for accurate determination of attitude
motion
• HAUSAT 1 by Hankuk Aviation University, South
Korea
– GPS receiver, experiment on deployment mechanism of
solar cell panel and space verification of homemade sun
sensor
• CP1 by California Polytechnic Institute, USA
– Test of sun sensor developed by Optical Energy
Technologies
• Mea Huaka (Voyager) by University of Hawaii, USA
– To test a 5.8-GHz active antenna (grid oscillator) for
high bandwidth communication (does not require
deployment of antenna)
• NCube1 by Norwegian University of Science and
Technology
– Raindeer……….
Fourth Batch = full of mysteries and was scheduled
to launch in September 2006
• CP4 by California Polytechnic Institute, USA
– No transmitter….?
• CAPE-1 by University of Louisiana, USA
– ??? Seriously no info on actual mission
• CP3 by California Polytechnic Institute, USA
– Three-axis magnetorquing experiment
• Libertad-1 (Freedom 1) by University of Sergio Arboleda, Columbia
– Camera and transmission of one stanza of the Colombian national
anthem.
This is the first Colombian satellite
• CSTB-1 by The Boeing Company, USA
– Big secret apparently
• MAST by Tethers Unlimited, USA
– Something to do with a triple cubesat held together with tethers
More failed cubesats
• AAUsat by Ålborg University, Denmark
– CMOS Camera, Sun sensors, magnetometer, and magnetorquers
– The antennas short-circuited resulting in poor communication
performance so only weak beacon signals were received. Also simple
two-way communication was established (pinging).
Batteries slowly died beginning after slightly more than one month in
orbit due to poor packaging (punch-pack).
• NCube2 by Norwegian University of Science and Technology
– payload consists of an Automatic Identification System. AIS is a
mandatory system on all larger ships, which transmits identification and
position data messages. The satellite will redirect these messages along
with messages from Norwegean reindeer collars.
