TITech(LSS)CubeSat 'CUTE I"...
The obejectives are design/development of pico satellite equipped with bus components under the leadership of we students, and reduce the total costs by using commercial off-the-shelf components.
Our Titech CubeSat project is coded "CUTE" (CUbical Titech Engineering satellite) project. "CUTE" also means our CubeSat is cute! This year, we are developing the first CubeSat: CUTE I.
Experience the design/development/operation processes of small satellite system.
Aquire the fundamental development technology and operation methodology of small satellite system.
By using some COTS(Commercial off-the-shelf) components not yet used in space, we reduce the total costs. Therefore we make the database of COTS components on the space-use.
This time is the first launching oppotunity for we students. Therefore, it make our motivation raise!
Development models and schedule
One CubeSat for the first launch in May 2002
We scedule to participate to launches subsequent to 2002
Size : 10 cm×10 cm×10 cm，Weight : 1 kg
Deployable solar battery paddle and three mono-pole antennas
Uplink : 144MHz(2m) Band Downlink : 430MHz(70cm) Band
Amateur Frequency Use
Sun-synchronous polar orbit, Height 650km
The MPA(Multi-Payload Adaptor) is capable of deployong 6 P-PODs, and CubeSat is ejected from the P-POD.
18 CubeSats in all are scheduled to be launched at the same time.
CW-transmitter of CubeSat transmits CW-telemetry, and we receive the signal at ground station.
FM-transmitter of CubeSat transmits FM-telemetry by two different protocol (Ax.25 and TITech original(Simple Radio Link Layer protocol, SRLL)), and we receive the signal at ground station.
Change the communication protocol by command uplink.
Broadcasting service of CW-telemetry data and FM-telemetry data on WWW.
[Deployment Mechanism Mission]
Experience the design/development process of on-orbit satellite system, and aquire the operation technology.
After the launch, track our CubeSat, and receive the CW-telemetry data.
(Tracking, Communication (CW, Data Downlink))
Deploy the solar battery paddle by command uplink.
(Communication (DTMF, Command Uplink), Deployment Mechanism)
Change the communication protocols of FM-Telemetry by command uplink, and then test data communication more certainly.
(Communication (DTMF, Command Uplink)
: This model is conducted to all kinds of functional tests. Development will finish by CDR.
LSS schedule to develop the followings models. We are now developing Engineering model.
Balloon Experiment Model: This models are conducted to ISAS baloon experiment(Communication test, May, 2001)
EM(Engineering model): This models are conducted to functional test, vibration test and thermal vacuum test
MM(Mass Model)：Mass model is equal to FM in terms of mass characteristics.
FM1,2(Flight Model)：Flight model(FM1) and its backup model(FM2)
