CubeSat Testing with Class AAA LED Solar Simulator

Any Space Light Condition Replicated in Your Lab

G2V's LED Solar Simulators Are Trusted By

Test Your Cubesat Under Full Spectrum Space Light

You’re making a small satellite, getting ready to launch it as a secondary payload into Low Earth Orbit. It’s carrying sun sensors, star trackers, attitude control subsystems, and solar cells to power it all. You’ve miniaturized your technology and want to make sure it’s all mission-ready.

You’re looking to test your entire CubeSat before it leaves the ground, and you need to trust the results.

You need a light source with high spectral fidelity to accurately assess solar charging. To correct anomalies and degradation pathways before orbit.

G2V’s LED solar simulators output large-area, full-spectrum light replicating conditions found in outer space and beyond, so you can confidently test your entire solution right here on Earth, for conditions anywhere you can imagine.

You’re reaching for the stars. We’ll provide the sun.

Accurate Star Tracking for CNES Engineers

Problem: CNES, France’s space agency was developing the star tracker for the rover of the 2024 Martian Moon eXploration (MMX) mission, and needed an accurate way to ground-test this vital part of their attitude and orbital control (AOCS) subsystem.

Innovation: G2V provided CNES with a large-area, yet compact, solar simulator that could fully illuminate their devices, with the freedom of high spectral tunability.

Outcome: CNES engineers were able to individually tune LED channels to probe device sensitivity under different illumination conditions. They made a custom jig for testing at different angles and were so happy with the results that they quickly loaned the instrument to colleagues for their work on solar modules.

How New Standards Demand Higher Solar Simulator Quality

While you’re testing, you need to be conscientious of your budget, so every experiment counts. You need assurance that you’re getting the best test equipment for your money. The 2020 update to the IEC-60904-9 standard for solar simulators introduces two new metrics that raise the bar for solar simulators across the industry, allowing for increased transparency and the ability to differentiate passable solar simulators from exceptional ones. So you can get the best solar simulator and move quickly to your testing. Our comprehensive IEC-60904-9 article covers:

The two new metrics of spectral coverage and spectral deviation
The new A+ classification
Evaluation of several different industry solar simulators according to the new metrics

FAQs From CubeSat Experts

Do your solar simulators include a shutter?

No. Typically our customers turn the solar simulator’s output off and on. The short LED warmup time and absence of excess thermal emission mitigate the need for a shutter for many users.

What UV protection do I need for your solar simulators?

The answer depends somewhat on the product model in consideration. For any product models that only cover wavelengths from 400 nm and above, no UV protection is needed, although we do recommend safety goggles for the strong blue light (and for many of the same reasons you wouldn’t stare at the sun). For solar simulators that include 350 nm – 400 nm coverage, we recommend wearing protective clothing or goggles for any body parts that may be under the simulator’s irradiance for longer than the allowable maximum exposure times. Note that our solar simulator is NOT designed for human exposure.

Can you produce the spectrum in space, AM0?

Yes! We provide AM0 calibration with all of our solar simulators.

What are the highest and lowest wavelengths your solar simulators can produce?

Our maximum spectral range is currently from 350 nm to 1500 nm. While there are some LEDs that reach higher and lower wavelengths, their performance and cost are not quite at the level needed for a robust and competitive solar simulator solution. G2V is always monitoring LED material developments, however, so if a wider spectral range is needed for your application, get in touch and we can discuss the possibility of a custom solution, or the inclusion of such a solution in our product roadmap.
