1 Greeting!

Welcome! CUTE-I developed at Matunaga Laboratory Tokyo Institute of Technology have two indipendent transmitter, CW and FM. Normally, CW will send data from space anytime and FM will be sent only when there was a command for it from Titech ground station.

For schedule of CW and FM at each pass, please see the following page.

#link to operation schedule

This page will introduce following things to receive data from CUTE-I.
*Radio Frequency
*CUTE-I's Transmitter
*Ground Station facility
*Titech's anntena facility
*Sound example(.wav)

 

2 Receiving Frequency
CW Bcon 436.8375MHz

4 Ground Station Facility

Titech's ground station is operating CUTE-I by following facility.(NOTE: this is just an example for receiving and does not mean that you must present this system to acquire data from CUTE-I)

*430MHz band antenna. (better if it is possible to control the elevation and azimuth)
*Amature radio tranceiver
*TNC with AX.25 decoder

If you successed to reveive data, we really appriciate if you can send information about your receiving equipment. We would like to open your equipment setting to other people by web and make easy receiving environment for CUTE-I.
