SMAD Portal vs Epsilon3
Ops procedures vs end-to-end mission engineering
Space ops teams running procedures in Epsilon3 and evaluating upstream engineering tools
- Your primary need is live test and operations procedure execution with step-by-step telemetry capture
- You run integration, launch, or mission ops as your main workflow
- You need deep procedure templating with dependencies, conditionals, and signoffs
- Your team is already on Epsilon3 and the ops workflow is their daily driver
- You need to design the mission before you operate it — requirements, budgets, and phase gates come first
- Your work spans systems engineering, not just procedure execution
- You want orbit design, mass / power budgets, and risk registers in the same workspace
- You want AI-assisted requirements generation and trajectory optimization during design

Switching from Epsilon3?
Keep running ops procedures in Epsilon3 — SMAD Portal does not replace procedure execution
Import your mission’s requirements, risks, and budgets into SMAD Portal to close the design loop
Use SMAD Portal’s Test Procedures and AI Test Case Generator to draft the procedures Epsilon3 will execute
Export procedure drafts from SMAD Portal and upload them to Epsilon3 as starting points
Frequently Asked Questions
Does SMAD Portal replace Epsilon3?
No — the tools solve different problems. Epsilon3 is an operations platform for executing procedures during integration, test, and flight. SMAD Portal is a mission engineering workspace for the design, requirements, and planning phases. The two complement each other: design in SMAD Portal, execute in Epsilon3.
Can SMAD Portal generate procedures for Epsilon3?
Yes. SMAD Portal’s AI Test Case Generator converts requirements into test procedures with pass criteria and steps. These can be exported and uploaded into Epsilon3 as a starting point. This closes the loop between verification requirements and procedure execution.
What about ops dashboards and automation?
SMAD Portal includes an Operations Dashboard with a workflow automation builder and a dashboard layout builder for mission operations. For live procedure execution with conditional logic and telemetry capture, Epsilon3 remains stronger.
Is SMAD Portal cheaper than Epsilon3?
Both are subscription SaaS. SMAD Portal starts at $29/month per user. Epsilon3 is typically priced per seat with higher entry points for ops teams. Most customers run both tools rather than choosing between them.
