Power Testing That Accurately Simulates Real Space Conditions

Validating power systems and payloads in satellite programs isn’t just about passing test cases. It’s about recreating edge conditions that could cause mission failure. Traditional test benches can’t replicate transients, thermal shifts, or orbital profiles with the precision and repeatability that aerospace and defense (A&D) demands.

Accelerate Testing with Real Orbital Conditions

Our latest ATE system power solutions combine high-density power supplies, regenerative electronic loads, and battery emulation software to give engineers full control over how systems behave across launch, eclipse, and payload operations.

The result? Faster test cycles, lower thermal footprint, and deeper insight into satellite power performance.

Use Case 1: Satellite Payload Testing

Validate Mission-Critical Payload Systems Faster, Safely, and with Absolute Confidence

Struggling to validate payload behavior under ripple, surge, or dropout events with enough precision? Use our high-power regenerative power supplies and electronic loads with sub-millisecond transient control to inject realistic faults and see how your system truly responds.

Start with 2 to 6 kW units for individual subsystems, or scale to 12 kW+ for full payload integration. You’ll get repeatable waveforms, clean transitions, and energy recovery on long-duration runs.

Use Case 2: Satellite Battery Emulation

Secure Mission-Grade Satellite Battery Testing

Power conditioning units (PCUs) don’t just regulate power; they’re the last line of defense when battery behavior gets unpredictable. If you’re validating PCU response to real-world conditions like state-of-charge (SoC) drift, orbital temperature swings, or eclipse transitions, physical batteries introduce more risk than realism.

Instead, emulate these profiles with our high-power regenerative DC power supplies: safe, repeatable, and programmable to the millisecond. Use 4 to 12 kW units for subsystem-level tests, or scale up for full-mission validation with high fidelity and zero thermal overhead.
