3D MicroG Start-up Module

Abstract

This document is provided as a rough outline of requirements and additional details for the design of the 3D Micro-G module responsible for detecting the host vehicle’s apogee and commencing FDM prints during the target time-interval of flight. The content is ordered as follows:

1. Definitions
2. Mission Timeline
3. ADDAM Requirements and Related Components
4. Enumeration of ADDAM Components

1. Definitions

• APW (Apogee Printing-Window) – the target interval of time after takeoff and before landing during which FDM print(s) are to be performed. (Roughly 5 minutes in length)
• ADDAM (APM Detection and Data-Acquisition Module) – the module (hardware and software) responsible for detecting the onset (and conclusion) of APW, commencing the FDM print(s), and acquiring various non-critical data throughout flight

2. Mission Timeline (rough)

1. Vehicle launches.
2. ADDAM begins sensing for APW onset (and begins all other data-acquisition capabilities.)
3. ADDAM detects APW onset.
   • ADDAM immediately commences FDM prints.
4. Prints finalize during APW.
5. APW ends.
6. Spacecraft returns to Earth

3. ADDAM Requirements and Related Components

• The ADDAM must, requiring no intervention, begin sensing for APW immediately upon power-on. (Power-on must occur prior to APW.)
  • Accelerometer to sense APW
• The ADDAM may also acquire various environment metrics:
  • Visible-light spectrum video
    • Visible light spectrum light
    • Visible light spectrum camera
  • Infrared video
    • Infrared camera
  • Magnetic field (potential magnetic interference)
    • Magnetometer
  • “Real-time” timekeeping
    • If module is primitive (and time is too unreliable), potentially should be an external clock.
  • Amperage to and voltage across printer (or entire system)
    • Electronically interfaceable ammeter and voltmeter
• Additional, Non-critical metrics
  • GPS NMEA sentences (altitude, UTC date-time, satellites tracking, etc.)
  • Ambient pressure
  • Ambient temperature (unless IR imaging suffices)
  • Relative humidity

4. Enumeration of ADDAM Components

Mission-critical:

• Power supply
• Accelerometer

Non-critical:

• Visible light spectrum light
• Visible light spectrum camera
• Infrared camera
• External clock
• Electronically interfaceable multimeter

Very low-importance

• GPS receiver
• Barometer
• Thermometer
• Hygrometer (humidity)
