Under the information for Chubusat 2 it says:


ChubuSat-2 provides the message exchange service. After the on-orbit
checkout of the satellite, you can use the service, sending your message
with amateur VHF (145.815MHz FSK 1200bps) then your message is written to
the on-board memory. Anyone can read your message with amateur UHF (437.1MHz
GMSK 9600bps) by sending inquiry message. The uplink/downlink format will be
available in this page.


I understand the 145.815 1200 bps FSK - this is the same as for NO-44, NO-84
and ISS.

But what is GMSK 9600?  How is that decoded?  And how does one request a
'message read' on this cubesat?
