Initialization

Mode	Description	RockBLOCK Status	ACS Mode	IMU Status	Exit Conditions
Boot	The RockBLOCK may not be on during this time due to CubeSat's proximity to the ISS.	Sleep mode	Off	Off	Two hours have elapsed
Alive Signal	This mode allows us to communicate with the CubeSat at one time before the ACS is activated.	Downlink period of X minutes	Off	Off	X minutes have elapsed RockBLOCK downlink hard faults
Low Power Alive Signal	This mode allows us to communicate with the CubeSat at one time before the ACS is activated in a power saving state.	TODO	TODO	TODO	TODO

Outstanding Questions

• Should alive signal allow for multiple RockBLOCK hard faults?
• Should IMU be on during boot?
• How does the IMU determine the CubeSat is stable during Detumble & Spin?
