SEEDS II was developed by students at Department of Aerospace Engineering, College of Science and Technology, Nihon University since 2001. SEEDS is nano satellite which size is 10cm cubic and weight is 1kg.

[edit] Payload characteristic

This mission involves obtaining “housekeeping data” that relates to the current state of health of the satellite (battery voltage, temperature data for each part, etc.) and then transmitting that data with the CW signal. Here is the list of the subsystems :

The middle mission involves transmitting sensor data (geomagnetism sensor, gyro sensor, and so on) with FM packet transmission (1200 bps, FSK) based on the AX.25 protocol. Furthermore, we analyze the temperature environment inside the satellite, and the attitude motion of the satellite by using the sensor data.
