Info Needed to Complete Eng. Model

CubeSat Status

*HELLO AND WELCOME TO THIS DOCUMENT*

INSTRUCTIONS:

1. Please comment below in the comments section that you have been to this page and read it

2. Please think about where your subgroup is at with your piece of the cubesat and add to the list of things we need to find out/create a new list to add the info you still need to complete your designs!

Below is a document made by students showing the connections between different subgroups for information (https://drive.google.com/file/d/1YlfCafDvZZr3dtDYSnGspkgO1cfMbwMm/view?usp=sharing)

If we break it down further, here is a working list of info needed for us to finalize all of our designs:

Sizes:

1. Electrical: powercore, voltage regulator, battery pack

2. Radio: Antenna, Tracking radio

3. Software: UART to USB connection

4. Sensors: Lens, altitude sensor, breakout board

5. Mechanical: screws, wires, connectors

Mass:

1. Electrical: powercore, voltae regulator, battery pack

2. Software: UART to USB connection

3. Sensors: gyroscope, altitude sensor, breakout board

4. Mechanical: screws, wires, connectors

Wattage:

1. Sensors: GoPro, breakout board

2. Electrical: voltage regulator

Temperature

1. Radio: Tracking radio, GPS

2. Electrical: Voltage regulator, battery pack

3. Sensors: GoPro, breakout board

Parts Still Needed Through Ordering:

1. Breakout board (once received it will go with the lepton IR camera)

2. Second battery pack (is it needed?)

Parts Still Needed Through Machining:

1. Body of CubeSat (depends on size info and power requirements)

Established Constants:

1. Overall size: 30cm x 10cm x 10cm

2. Max weight: 2.5kg

3. Total surface area: ~1500 cm²

4. Total volume: ~ 9000cm³

Temperature Commitments (doesn’t include GoPro and is incomplete):

1. Highest low operating: 0°C

2. Lowest high operating: 50°C

3. Highest low survival: -45°C

4. Lowest high survival: 80°C

5. Operating range: 0-50°C

6. Survival range: -45-80°C

Things Still Needed to be Figured Out:

1. Software/sensors code connection

2. How to work the ground station?

3. Does our math make sense with reality? (sensor res)

4. Wire connections

Needs to be Discussed:

1. CubeSat Orientation

   1. If testing for real orbit, the orientation should be how we want it to be in the final orbit

2. Placement of subsystem-weight distribution

   1. Inside Components:

      1. Radio: GPS, tracking radio, telemetry

      2. Electrical: powercore, voltage regulator, battery pack?

      3. Sensors: gyroscope, altitude sensor

      4. Software: UART to USB connection, RPi

      5. Mechanical: wiring

   2. Outside Components:

      1. Radio: antenna

      2. Sensors: VIS camera, IR Camera and breakout board, GoPro

      3. Radio- on the inside and antenna on the outward

      4. Electrical- on the inside

   3. Insulation

      1. Where do we need insulation to protect from both heat and cold?

   4. GoPro or not?

      1. Temperature endurance?

      2. Attachment to HAB structure?

      3. Coding platform/connect to Pi?

      4. Memory?

      5. Power?

   5. Launch pre-testing of system?

Launch Figures:

1. CubeSat orientation

   1. Where tether is connected

2. Length of tether

3. Link

   1. Force tolerance

   2. Placement of tether

   3. Student learning how to properly launch balloon

   4. Draw out possible balloon rates

      1. Draw out possible trading routes

   5. Deciding launch/tracking teams

   6. Materials/tools possibly needed for retrieval

      1. What would be needed for different environments

         1. Possible environments:

            1. Woodland

            2. Water

            3. Field

            4. House/backyard

            5. Urban area

            6. Others??

         2. Possibly look at days that we hope to launch for airline paths at the closest airports and scope a few potential dates
