Table 1. Summary of each of operation modes

Mode	Description
Separation mode	• Separation switch behavior when separating a satellite from the POD• UHF/VHF antenna deployment (15 min. after ejection)• Beacon signal transmit (10 second interval)• De-tumbling control
Normal mode	• Satellite commissioning and condition check• Maintain beacon signal transmission and de-tumbling control• Waiting for ground command
Mission mode	• Combustion experiment• Biological experiment
Communication mode	• Transmission of mission data• Transmission of housekeeping data
Safe mode	• Maximize power charging while keeping only main systems running• Reboot the system when a system error is detected

POD, picosatellite orbital deployer; UHF, ultra high frequency; VHF, very high frequency.
