Hello, everyone. We are NEXUS development project team in Nihon University. Your receiving reports are used for confirmation of NEXUS state. Thank you for your cooperation. We will report the result of nighttime operation today.

CW custom mode
NEXUS are orbiting at CW custom mode now. CW format is following.
JS1YAVNEXUS04 (Sattime : 8words) (SW info : 2words) (Reset info : 10words) (Bat Vol : 4words) (Gyro x : 4words) (Gyro y : 4words) (Gyro z : 4words)
Total : 49words (characters)

○Operation Result
We performed nighttime operations twice.
"CW custom operation(437.075MHz)", ”SSTV operation(Bus transmitter, 437.075MHz)”, "AFSK1k2(Bus transmitter, 437.075MHz) Real-time HK data downlink(30s intervals)".
