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.
