FAQPage Schema
How do I size a solar array for a spacecraft in LEO?▼

Solar array sizing for a LEO spacecraft requires calculating orbit-average power needs and eclipse duration. This Skill sizes solar arrays by evaluating the power profile, applying derating factors, and verifying a positive energy balance across the orbit.

What is the best way to calculate spacecraft battery sizing and depth of discharge?▼

Spacecraft battery sizing is calculated by evaluating eclipse energy balance and depth of discharge (DoD). This Skill selects batteries by modeling cycle-life requirements and ensuring the energy margin meets the mission life constraints.

How do I generate a spacecraft power budget with energy margin checks?▼

Generating a spacecraft power budget involves aggregating payload power profiles and verifying positive energy balance. This Skill creates end-to-end power budgets with automated margin checks for varying orbits and temperature conditions.

Can I design an EPS for deep-space missions with varying eclipse cycles?▼

Yes, you can design an EPS for deep-space missions with varying eclipse cycles. This Skill applies EPS sizing and energy balance verification to LEO, GEO, and deep-space profiles, accommodating varying temperature and eclipse duration conditions.

What inputs do I need to start spacecraft EPS design and bus architecture sizing?▼

Starting spacecraft EPS design requires the target orbit, payload power profile, and mission life duration. Providing these parameters triggers the Skill to generate a complete EPS design, including solar sizing and battery selection.
