UNISEC 2005

Intelligent Space Systems Laboratory,University Of Tokyo

We have evolved some very ambitious and practical aerospace engineering projects in 2005-ARLISS , CubeSat XI-IV & XI-V , PRISM , S-310 rocket experiment , Nano-Jasmine and GSNPJ. Above all , we had gone through 2 flight operation within half a year,CubeSat XI-V( 10/27/05 ) & S-310-#36 (01/22/06).
CubeSat XI-IV , launched on 06/30/2003 , is still working well. And we got a chance to launch it's sister "XI-V". The main mission of XI-V is evaluation of CIGS solar power cells , especially on its long term reliability. The launch was successful and we had already obtained some telemetry data from the satellite. We are also now developing the next generation of CubeSat - "PRISM". Our development is now in EM phase , and we are now expecting its launch campaign in 2007.
S-310 rocket is a sounding rocket provided by ISAS/JAXA. We did an experiment to expand "Net" in space with the rocket on 01/22/2006. The experiment was very successful and we are now analyzing the obtained data.
On the other hand, we are now considering how to develop the nano-sized space telescope satellite called "Nano-Jasmine". NAO is the collaborator in the project. We are trying to develop the satellite simulator so that we might find some ways to satisfy its mission requirement: extremely high accuracy of attitude , motion and temperature.
As a member of GSNPJ, we had been playing an important roll not only in Japan but also in the worldwide. We had some remote-control experiment with Hawaii University and Cal-Poly.

Nihon University

In the current year, we (Nihon University, College of Science and Technology, Aerospace Structural Engineering Laboratory) did two activities for the development of the satellite.
1:SEEDS Project
We had developed a CubeSat named SEEDS (Space Engineering EDucation Satellite)since 2001, and finished the development last September. We exported SEEDS to the California Polytechnic State University (Cal Poly) which manages the CubeSat project. The activities for the project are summarized as follows.
Acceptance test, operation test, battery charge(April), battery charge(September) at CalPoly
Presentation, PR activity(JSME Mechanical Engineering Congress, IAC2005, Ham Fair, Space Development Forum, etc)
Development of ground station and it's network(Ground Station Network)
2:SPROUT Project
We have started SPROUT (Space Research On Unique Technology) project as the second micro satellite project of our university. We use almost same technology for the bus system as that of SEEDS, and will newly develop the demonstration mission of the extension of an inflatable mast, and radio communication service for hum operators. SPROUT project are the education of the students and research/development on the objectives of space engineering. Now, we are developing a Bread Board Model.

Matunaga Laboratory,Tokyo Institute of Technology

Cute-1.7+APD is the successor of the Cute-1 nano-satellite, developed and built by the second generation of students of the Tokyo Institute of Technology Matunaga Laboratory for Space System (LSS). The Avalanche Photo Diode sensor module, or APD, embarked on this 20cmx10cmx10cm nano-satellite was also developed by the Tokyo Institute of Technology Kawai Laboratory. "Cute-1.7+APD"-#1 is scheduled for placement into orbit as a subpayload of the JAXA M-V-#8 Rocket in February 2006. The separation mechanism for release in orbit was also developed at LSS. It is based on the TSD experiment regarding CUTE-I.
LSS developed an original latch-lever and nylon yawn separation system for Tokyo Tech¨fs CubeSat named CUTE-I. LSS developed an orbital experimental apparatus (Tokyo Tech Separation System Demonstration, TSD) using M-V-6 sub-payload space to verify our separation system function. M-V-6 rocket was launched successfully on July 10, 2005. In the flight, TSD worked perfectly without incident. The orbital demonstration of TSD using the sub-payload contributes to create additional invaluable importance of M-V rocket. In this paper, TSD missions are introduced and launch results are described.
2 CanSats were developed at LSS. One is OpenClass and the other is Regular Class. OpenClass has 3 missions. 1 is that OBC installed OS controls a digital camera via USB interface. We chose TS7200 with many interfaces as OBC. 2 is attitude determination by several sensors. 3 is to demonstrate the performance of the new version two-way radio. Our objects of balloon experiment at Noshiro are followed from the minimum success level which we determined for ARLISS. The results were good enough. In ARLISS, OS booted normally after released from the rocket. Gyro and Magnetic sensors also worked normally. OBC controlled the camera via USB and took 36 pictures. But CanSat did not acquire the GPS data and then the Comm. did not transmit the data. However, we could hear the sound of turning on the radio equipment.
LSS participated USSS 2005 at Hawaii University Manoa Campus. We made a summary report of the activity.

Kyushu University

Two satellite development projects named QTEX and QTEX-PR are being advanced by Kyushu University.
QTEX(Kyushu University Tethered Satellite EXperiments) is a micro tether satellite and its main mission is a demonstration of tether deployment system QTEX consists of two satellites connected with thin tether. It launches, these two satellites are connected, and this satellite with 50cm cube and weight of 50kg is assumed a piggyback satellite of H-IIA.
We are developing QTEX-PR that is only one of QTEX satellites. This satellite is a satellite to specialize only in the bus part and it doesn't contain tether mission. It aims at the completion in 2006 and is the test stage of EM now.
They are joint projects with Kyushu Pioneers of Space (QPS).
In addition, CANSAT activity is doing to acquire the developmental techniques of satellite.

Soka University

This paper reports three CanSats developed in ARLISS2005, and CubeSat "Excelsior" which is under development in Soka University.
In ARLISS2005, two experimental CanSats for CubeSat and one rover type CanSat for Comeback Competition were developed. One of experimental CanSats is for developing technology of using CMOS image sensor. Another one is for communication system demonstration and basic development of re-configuring COTS SRAM-based FPGA.
Soka University CubeSat "Excelsior" has two missions. One is taking earth image by using commercial CMOS image sensor. Another one is space demonstration of CubeSat¨fs computer system. This system is designed especially for nano-satellite.
Specifically, this system uses a COTS FPGA and embeds soft-core CPU in FPGA. The CPU has multiplexed functional blocks (command controller, instruction, execution unit, resistor and others). Usually, TMR (Triple Module Redundancy) needs triple power requires, volume and cost. However, nano-satellite is not able to offer that much volume and power consumption. Therefore, this system which multiplex functional blocks is suitable for nano-satellite.

Osaka Prefecture University

We have been developing a small non-combustion rocket taking safety into account. In general, students face danger in rocket projects because the rocket engine has combustion processes. Focusing on safety, economy and ecology, we study a non-combustion rocket engine using LN2 and H2O. We have developed a non-combustion engine system. The developed engine was found to generate enough thrust to launch a small rocket. We have designed and developed a small rocket equipped with the non-combustion engine. We call the small rocket CEES (Cryogenics, Economy, Ecology, Safety). On March 20th, 2005, we launched the non-combustion rocket CEES-1. This rocket was successfully launched and reached approximately 60 m high. The successful launch of the small rocket using non-combustion engine is the first in the world. On the basis of this success, we began developing a new non-combustion rocket CEES-2 for launching a Can-Sat. We launch ed CEES-2 with a Can-Sat on March, 2006. Safe and low-cost non-combustion rockets of this type are expected to facilitate rocket launch and to promote space development by students.

Laboratory of Space Systems, Hokkaidou University

CAMUI (Cascaded Multistage Impinging-jet) system is the combustion system of hybrid rocket to improve fuel regression rate with impinging jet heat transfer by the supply system that combustion gas and oxidizer impinge solid fuel surface. In this research, we perform combustion experiment of the two motors that combustion chamber configurations are analogy with the condition that oxidizer mass flux is equal and examine the influence of scale difference on fuel regression rate. This homothetic ratio is 2.4. Thrusts of these motors are 62.5 kgf class and 360 kgf class. Diameters of these fuel blocks are 57.5 mm and 138 mm. The propellant is combination of polyethylene and LOX. We perform experiment for a change LOX flow volume and combustion time and then measure fuel regression rate of recovered fuel blocks. The result is that two motors¨f average fuel regression rate was comparable on these port and back end surface. On these forward end surface, 62.5 kgf class motor¨fs average fuel regression rate was greater than 360 kgf class motor¨fs.

Yuasa Laboratory, Tokyo Metropolitan Institute of Technology

We are studying a SOFT-HR (swirling-oxidizer-flow type hybrid rocket) using LOX (liquid oxygen) as an oxidizer to launch a payload with a weight of 6kg to 60km in altitude. As main technology, LOX vaporization nozzle (device vaporizing LOX with a re-generative cooling system at an outer wall of a high temperature nozzle) have been proposed. So far vaporization tests of an experimental nozzle were conducted below the design injection pressure and mass flow and LOX could be vaporized safely. In this study, based on the result of the experimental nozzle tests, design was changed to channel type and this type nozzle was made. Combustion tests of a 1500N engine for SOFT-HR were conducted using GOX in order to know about problems in enlarging engine. Reliable ignition and stable combustion was achieved. Thrust reached 1500N. Swirling flow had an effect in the improvement in a performance at the large engine.

Tokai University

Tokai Student Rocket Project (TSRP) was established for a purpose of the space science and engineering hands-on education as an academic program at Tokai University Shonan campus in 1995. TSRP started to have rocket launch collaboration with University of Alaska Fairbanks (UAF) from 1996. In January 2000 and March 2002, two collaborative sounding rockets were launched at Poker Flat Research Range in Alaska and all of payloads were successfully carried to the apogee of 79 km and 89km high, respectively. The third collaborative rocket is going to launch in March, 2007.
The other TSRP project is hands-on hybrid rocket experiment. Six small hybrid rockets were launched to the level of 300-700m high in 2001 at Alaska and in 2004, 2005 at Japan. A new hybrid rocket will launch under the help of the University Space Engineering Consortium (UNISEC) in March 2006.
This training and educational program provides students with the opportunity for hands-on experience to design, to construct, to test sounding rocket payloads and hybrid rockets by use of low cost devices, and to analyze acquisition data after launches. This program has proven to be very effective in providing students with practical, real-world engineering design experience, and this program also allows students to participate in all phases of a sounding rocket mission. Also students learn scientific knowledge, engineering technique, public affair and system management through experiences of cooperative teamwork, presentations and collaborations. In Tokai team, approximately 60 student participants, who range from freshman to graduate students, are independently working and studying interdisciplinary research and extensive techniques. We are going to present our student activities and problems about the hand-on educational project in Tokai University.

Space Development Forum Executive Committee

Today, there is a shift of the circumstances of Japanese space activity. Of course, there is still no change in the situation that space activity needs high technology. On the other hand, recently a linkage between the space activity and the international politics has heightened. And space business has become active. The needs for law and rule on space activity are increasing too. Fixing our eyes on this stream, we SDF aim to think about space activity focusing on the field of social science like business, policy and law. And we also aim to provide chance to get various points of view about space activity to many people.
For example;
1.Business, law, technology and policy workshops. They are held once a month.
2.Holding"SPACE Development Forum"every summer, gathering students from various fields.
3.Publishing the booklet about space business, law, technology and policy,"SDF MOOK."
4.Research, poster display and hosting events with other organizations. Etc

The Student Rocket Committee

The student rocket committee is a subcommittee which consists of three members of the old Student Committee of Rocketry and is developing the model rocket for CanSat discharge. One person has participated each from next three universities, Nihon University, Tokai University, and Waseda University. In ARLISS opened in the U.S. Nevada Black Rock desert every year, problems, such as failure of a parafoil deployment and inoperative by vibration of a rocket, have arisen. In this committee, we thought that was one of the causes which have not done the launch examination in advance which used the rocket in Japan. However, since the rocket for launching CanSat did not exist in Japan those days, so we started the project of developing the model rocket for launching CanSat. This CanSat discharge rocket development project for domestic was undertaken for two years from 2002 to 2004. Then we developed the rocket which called SCR-002 Rocket can launch over 100m-150m and emit 300g CanSat of 350ml size. This rocket is a rocket which succeeded in a launch of CanSat a total of 5 times which Nihon University the Nakamura and the Miyazaki laboratory, and the Waseda University aeronautics-and-space association manufactured and which has a track record very much.
The other projects which this committee undertook have a model rocket launch experiment in the United States. This experiment launches the large-sized model rocket manufactured in Japan during the holding of ARLISS2004 in the U.S. Nevada Black Rock desert. This experiment was carried out in the meaning which checks whether it can carry out at places other than Japan when wanted to conduct the experiment using the handmade rocket in which it cannot experiment by advanced restriction etc. in Japan in the future. The experiment checked these points, when the rocket mainly manufactured in Japan was able to be conveyed safely, a solid rocket motor was able to be obtained, and it was fixable in the field if damaged during transportation. The rocket which launched by manufacturing includes what was manufactured there, and is three sets at all. A launch of SCR-004, a Duel rocket, and a SCR-002B rocket was performed, and it succeeded in a launch of all the bodies. The Japanese rocket was launched for the first time by ARLISS by this experiment, and, as a result, it turned out that a launch of a rocket is possible even in the United States.

Kagawa University

Recently, service on the orbit becomes important as the space development advances.The method of moving the space machine using Tether on the orbit is effective to miniaturize and to save the fuel.The Tether space robot is a system that a small robot on the end of Tether that expands from the mother ship.This system can control posture by the robot operation using the Tether tension.
The space proof of a new system like the Tether space robot is difficult in the space development of the past. Because the proof of reliability and safety is difficult.Therefore, Pico satellite that have dominant point on short-term develops and Low cost is the best for the space proof experiment for a new technology like the Tether space robot.In present space development, service on the orbit for which the Tether space robot is most effectively used is disposal of the space debris.This service is an urgent problem. Therefore, developing in a short term is important.
We have the Pico satellite development project for the space proof of "Tether space robot". The developed Pico satellite is composed of two bodies. Each size is about 15cm cube and about 2.5kg. This report mainly explains the outline of STARS-I.

Group of Spacecraft Dynamics, Chaotic Systems Engineering, Hokkaido University

The group of Spacecraft Dynamics in the Chaotic Systems Engineering Lab. takes part in the Hokkaido Satellite Project with Hokkaido Institute of Technology (HIT). We have developed the attitude determination and control system (ADCS) in the project. In this fiscal year, we developed the ADCS for the HIT-SAT which is a micro satellite, which is about 2kg, aimed at the technology demonstration for the Hokkaido Satellite. The purpose of the ADCS for the HIT-SAT is the initial attitude acquisition control after separation from a rocket. In this control, the satellite spins around a pitch axis and directs the axis to the sun within 10 degrees. We confirmed the PWM drive of magnetic torquers, data accession from attitude sensors (a magnetic sensor, a sun sensor and a gyro) and communication between the ADCS and the Data Handling Unit through BBM of HIT-SAT.
We also studied the method of fast and accurate image classification for a hyper spectrum camera which is developed by HIT in this fiscal year. A hyper spectrum camera has received much attraction in the remote sensing field recently. We aimed to speed up the image classification without reduction in accuracy by projection of high dimension data on a lower dimension subspace. From the experimental results, making dimension of data lower by correlation value between bands and classification by SVM, we confirmed that the speed of classification became ten times.

Akita University

Activity of the entire Akita University
Akita University began the launch of the space satellite that produced it for myself, and aim Akita University Cansat team was begun and the start-up activity began in April, 2005. All members of the participation member acted from the state within at all like the knowledge etc. of the electric circuit and the programming and it participated in the Noshiro space event. The Rover project that centered on Cansat project that minded the inside ..the Cansat production afterwards.. and the Rover production was started up, and Cansat project participated in Fukuoka IAC commemoration comeback competition. The high Hybrid rocket project and the organization integration started up in August, 2005 are done in February, 2006, and it will act as a space of the student of Akita University project centering on three sections of announcing to public, the satellite, and the rocket in the future.
Cansat project activity
Seva1 project
The Seva1 project to participate in the Noshiro competition was the first Cansat production Cansat team, and started acting from the state where nobody completely had the knowledge of the electric circuit and the programming. What taken from dialect "..having.." of Akita, and "For the time being" and "Moreover" etc. the meaning Calling by the way Seva has a wide meaning. It was used most, and " ..having.. ..alive dialect.." was assumed to be a name of founder Cansat in Akita Prefecture according to the thing with feelings be able ..wanting the solution of various problems.. by saying in the state without the technology at all, "Let's try for the time being" the reason to have adopted this name.
Seva2 project
The Seva2 project to participate in the Fukuoka competition was developed as a succession machine of the Seva1 project. It aimed at certain operation as mission success, and a new function assumed ROM only to install it. However, because the method of writing in ROM as soon as the signal of GPS was not able to be received had not established it, installing GPS and ROM was put off in the Fukuoka competition. Therefore, it did not operate in the Fukuoka competition due to the trouble of the power supply system though it aimed at the flight characteristic of Parafoil and the proof of a wireless system.
Rover project activity
Project management is most important at planning way to carry out project.
This was founded by cansat team leader's opinion. Rover is easy to understand its own movement. And they have impact that connected to fun.
But we think rover is more hard than flyback type cansat. Because rover have many mechanical parts. For example geared motor and body structure.
In January we have a plan to construct snow mobile , and construct radio control model to manufacture structure.

Yasuda Women's University

We, the members of Yasuda Women's University CSS(Cube Sat Show) Project, are eager to introduce the fact that some students studying in the University of Tokyo launched a small-sized satellite in 2003 for the first time in the world.
Although we have no skill of developing a satellite ourselves, we have the skills to create a movie using 3-D computer graphics, so we started the project to make a DVD to introduce CubeSat.
At the beginning, we had very little technology with which to make the movie, but with the help of the University of Tokyo, we could complete the project.
We plan to send these DVDs to many high schools or companies in japan. We hope that many people will know about the fantastic CubeSat and will have a dream about space.

We carried out the ESD ground tests on solar array and other components of domestic satellites since 1999. Space systems such as a satellite, an interplanetary probe or a space station, must endure the extremely harsh environment made of space plasma, hyper-velocity particles, radiation, ultraviolet ray, atomic oxygen, vacuum, thermal cycles and so on. Even if a component breaks down, it is usually impossible to repair. Therefore, we are often required to test spacecraft thoroughly. Making a thing that works in the harsh space environment is an essential technology needed to explore the last frontier, space.
We carry out research and development of space environment technology that is necessary to achieve the next-generation large-scale space utilization such as high-speed broadband communication, high-precision positioning, remote sensing, material creation, sight-seeing, exploration, energy generation. Its mission is to serve the humanity by contributing to development of space activity.
