SOFTWARE FOR THE SPACE INDUSTRY

EVERY PROCEDURE. EVERY MISSION. ONE RECORD.

Epsilon3 runs the AIT, launch, and on-orbit procedures that get spacecraft built and flown — every step, signature, and deviation captured as it happens, gated against the live telemetry that tells you it's safe to proceed.

TRUSTED BY THE MOST CONSEQUENTIAL SPACE PROGRAMS

WHY SPACE PROGRAMS CHOOSE EPSILON3

PURPOSE-BUILT FOR HOW HARDWARE ACTUALLY GETS TO ORBIT.

Generic MES and paper travelers weren’t built for AIT floors, countdown nets, or telemetry gates. Epsilon3 was.

AIT, bench to pad

EVERY AIT STEP, SIGNED AND TIMESTAMPED.

Run assembly, integration, and test procedures from one system, with custom pass/fail criteria evaluated against live functional and telemetry data as the step executes — not reviewed after the fact.

20x FASTER THAN PAPER PROCEDURES

Cleared before you evaluate

ITAR, EAR & FEDRAMP HIGH OUT OF THE BOX.

ITAR and EAR compliant, FedRAMP High authorized, deployable on AWS GovCloud — the export-control review that usually adds a quarter to procurement is already answered before your first call.

FEWER THAN ~80 SAAS VENDORS HOLD FEDRAMP HIGH

Telemetry in the loop

TELEMETRY INSIDE THE PROCEDURE, NOT NEXT TO IT.

Pull live TT&C data straight into the step itself, so an operator running a propellant load or a wet dress rehearsal sees the exact reading that gates the next signature — no second console, no tab-switching mid-run.

REAL-TIME GATING ON LIVE SENSOR DATA

Cadence without the tax

SCALE TOWARD DAILY LAUNCH WITHOUT SCALING HEADCOUNT.

One record of what ran, who signed it, and what changed between revisions — so a growing manifest doesn’t have to mean a growing integration team standing between your systems.
