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.
