Payload Requirements IREC-2022

Mission Critical Requirements

Driven by Rules and the Rocket

• The payload must be deployed from the rocket.
• The payload must conform to the 3U cubesat form factor.
• The payload must weigh at least 8.8lbs (4kg).
• Only 20% of the payload mass can be non-functional.
• The payload must be recoverable.
• The payload must have redundant recovery systems.
• The payload must land at less than 30 ft/s (9.1 m/s).
• The payload's location must be real-time tracked by ESRA Mission Control Center (MCC).

Primary Objective Requirements

Not mission critical, but top level

• The payload will live stream video to the ground during flight.
  
  

Derived Requirements

Requirements derived from MC and PO requirements

• drogue chute
  
  • passive deployment
• one downward facing camera
• local (non-streamed) camera upward/sideward (maybe)
  • no reason to not put as many we can fit/power
  • vertical would be cool (see the parachute)
    • less overlapping information that downward and upward
• name idea: COTS in 4K
• Tracking: BRB
• we need to power the cameras
  • whole lotta 2S LiPos
  • 2x Flight computers
  • 2x Cameras (and transmitter)
• we need a video transmitter
  • 5.8 GHz 1W
• how do we get signal to the ground
  • directional antenna somewhere
  • cool modulation - spreading sequence, something else

Secondary Objective Requirement(s)

driven, optional, fun

• the payload must speak in jims voice
• Small streamer for visibility
