ARLA/CLUSTER: Ham Radio Mode-J Transponder for NEXUS CubeSat

[João Costa > CT1FBF]

The Japan AMSAT Association (JAMSAT) and students at the Nippon
University are jointly developing a CubeSat called NEXUS which will
have a 145 to 435 MHz (Mode-J) transponder and a 38 kbps data downlink

Nippon University students have previously developed the SEEDS and
SPROUT satellites. NEXUS is an achronym of “Next Education X (cross)
Unique Satellite”, it will be 1U CubeSat with a mass of between 1 and
1.5 kg.

The NEXUS team hope to:
● Provide amateur radio communications via the 145/435 MHz transponder and SSTV
● Download pictures from the 640×480 pixel camera
● Operate the data downlink at 38400 bps QPSK
● Compare the performance of the data downlink when using AFSK, GMSK
and QPSK modes

A launch opportunity has not yet been identified.
