Fragmented analysis
Mission trade-offs are spread across disconnected tools and files.
Aerospace engineering
Turning complex analysis into clear mission decisions
Ephemersys helps small satellite teams evaluate mission concepts, radiation risks, and engineering trade-offs before design decisions become expensive.
We assess radiation risks for deep space missions, from early design trade-offs to PDR/CDR-level analysis, and support satellite mission design with engineering analysis, simulation, and decision-ready trade studies.
The Challenges
Early mission decisions are too often made with fragmented tools
Space mission teams need to make architecture decisions before every detail is known. Orbit selection, communication windows, power budgets, radiation exposure, shielding, component placement, and lifetime constraints are all connected.
But these analyses often live in separate spreadsheets, scripts, desktop tools, and expert reviews. That makes it harder to compare scenarios, communicate assumptions, and move confidently from concept to design.
Slow iteration
Changing one assumption often means manually updating several analyses.
Unclear design confidence
Teams need to understand risks before committing to hardware, geometry, or mission architecture.
Products
Two focused tools for mission and radiation analysis
Ephemersys develops engineering tools that help space teams compare options, understand constraints, and make better design decisions earlier in the mission lifecycle.
SatZone
Mission analysis and scenario comparison for small satellite teams
Model mission concepts, evaluate orbit-dependent constraints, analyze communications, power, environment, and lifetime effects, and compare scenarios in one workflow.
Best for CubeSat and SmallSat teams, mission designers, NewSpace companies, universities, and early-phase feasibility studies.

Sector Tool
Sector Tool
Radiation sector analysis for spacecraft shielding decisions
Analyze spacecraft geometry, shielding distributions, and radiation exposure to support TID/TNID assessment, component placement, and shielding trade-offs.
Best for Radiation engineers, spacecraft design teams, component-level risk assessment, and proposal, PDR, CDR stage analysis.
