LignoSat is a 1U-sized CubeSat whose outside structure is mainly composed
of wood. In the development of wooden artificial satellites, we can produce wooden structures by using a familiar material "wood" and the usual manufacturing techniques. This will provide more people with the
opportunity to develop amateur satellites at a lower cost.
This satellite performs the following missions:
1. Amateur Radio Mission LignoSat will extract call signs of the amateur
radio stations from the FM packet data signals uplinked, and respond to
them by using the CW downlink and their call signs to send “thank you” messages. This shows the success of the interactive satellite communication using only UHF frequencies.
2. Educational mission Another LignoSat mission is to educate students to
learn about the characteristics of the satellite by acquiring its HK data
such as the internal temperature, the strain of the wooden structure, and
the Earth’s magnetic field and calculating the rotational direction and
rate of the satellite as well as observing the effect of the space
environment on the wooden structure of LignoSat.
Date and time of deployment: December 9, 2024, 20:30 JST/11:30 UTC +-90min
Downlink frequency of CW beacon: 435.82MHz +-Doppler
Please track the satellite using the orbital elements (TLE) of the ISS for
a while after deployment. As time passes, it will gradually fly ahead of
the ISS.
The first path in Japan is expected to be around 06:30 JST on December 10th
The antenna is scheduled to be deployed 30 minutes after deployment, so if
the deployment is early, it may be possible to receive the satellite during
the first pass in eastern North America (around 12:20 UTC).
If the deployment is late, it may be possible to receive the satellite
during the first pass in the EU (around 12:37 UTC).
A release event is scheduled to take place on the JAXA YouTube channel.
Please send your reception reports to
jh3bum@jamsat.or.jp thank you.
