SYS.TAXONOMY // 13 ENGINEERING DOMAINS
Spacecraft Engineering Topic Hubs
Every SatWiki specification, worked technical note, research monograph, and interactive Lab solver on nadir lab. is cross-indexed across 13 core engineering domains.
Electrical Power Systems & Li-Ion Batteries
Body-mounted GaAs solar cells, geometric cosine projection on 5 cm and 10 cm cubes, MPPT vs. DET architectures, and Li-ion depth-of-discharge cycle ageing in LEO.
Attitude Determination & Control (PMAC, B-Dot & 3-Axis)
Passive permanent-magnet alignment, Aharoni demagnetization limits on HyMu-80 hysteresis rods, B-dot magnetorquer detumbling, and CubeSat 3-axis reaction wheels.
RF Communications, Link Budgets & Antenna Deployment
UHF, S-band, and X-band link budgets, FSK/GMSK and LoRa CSS modulation, NiTi superelastic tape-spring antennas, and non-pyrotechnic Dyneema burn-wire release actuators.
On-Board Computing, CDH & Fault-Tolerant Flight Software
ARM Cortex-M, MSP430 FRAM, and RISC-V flight processors, watchdog hierarchies, brownout state machines, and SEU/SEL radiation mitigation for COTS avionics.
Structures, Thermal Control & Solder Joint Fatigue
AlbaPod 1P backplate flexural rigidity, CDS Rev. 14.1 CubeSat rails, two-orbit transient thermal balance, α/ε surface coatings, and Engelmaier leadless solder fatigue.
Micro-Propulsion, Drag Sails & Deorbit Systems
Cold-gas, electrothermal, pulsed plasma (PPT), and FEEP micro-thrusters, drag-makeup Δv budgets, and deployable drag sails for 5-year post-mission disposal compliance.
Orbital Mechanics, Thermospheric Drag & Lifetime
King-Hele orbital contraction, Kennewell–Voigt F10.7 solar-cycle thermospheric density, ballistic coefficients, and Solar Cycle 25 LEO orbital decay reconstructions.
Ground Stations, TLE Tracking, Doppler & SatNOGS
Amateur UHF/VHF Yagi and turnstile receive chains, mast-mounted LNA system noise temperature (G/T), SGP4 pass geometry, Doppler shift curves, and SatNOGS network integration.
Orbital Materials, Outgassing, Atomic Oxygen & Alloys
Al 6061-T6 vs. 7075-T7351 and Ti-6Al-4V backplates, ECSS-Q-ST-70-36C stress-corrosion cracking, ASTM E595 outgassing (TML/CVCM), RAM atomic oxygen erosion, and NiTi shape-memory alloys.
ITU / IARU Spectrum Coordination & Space Debris Rules
ITU API/CR filings, IARU amateur satellite frequency coordination, FCC/ESA 5-year post-mission disposal rules, and national space object registration.
Launch Vehicles, Rideshare Deployers & LEOP
Falcon 9 Transporter rideshares, Electron, Vega, AlbaPod and P-POD/ISIPOD deployers, OTV host spacecraft (D-Orbit ION), object cataloguing delays, and LEOP first-contact operations.
