Our Testing Process:
The Pinnacle
of Quality and Rigor

We believe that the true measure of a product's worth is how well it performs under real-world conditions. Our testing process is thus designed to be exhaustive, replicating the most rigorous conditions that our antennas will experience throughout their entire lifecycle.

We don't just test for the functionality of our antennas in space; we aim to recreate their entire journey.

Our qualification philosophy is to simulate a full lifecycle of an antenna—from the conditions they might experience in storage facilities to the rigors of the launching phase, the challenges they will face in orbit, and their overall resilience and performance throughout their operational life.

Our Testing Process

Qualification tests :

S-parameters are controlled between every step to validate no degradation of the performances of the antenna occured during the testing process.

Initial Functional Test:

We conduct detailed measurements of the S-parameters and the radiation pattern to evaluate the antenna's RF functionality under various conditions: Initial S-parameter tests serve as a reference performance for all subsequent tests.

Moist Heat Test:

To gauge resistance to moisture during ground storage prior to launch, the antennas are exposed to hot, humid conditions.

Vibration Tests:

To simulate the vibration conditions during launch (acceleration, engine combustion instabilities, sound pressure on the fairing), our antennas undergo a vibration tests: quasi-static acceleration and random vibration tests to ensure structural integrity.

Shock Tests:

These tests ensure that the antennas can withstand sudden and extreme forces, typically experienced during stage separation or appendices deployment in-orbit.

Vacuum Thermal Cycling:

Mimicking the vacuum of space, this test evaluates the antenna's performance under extreme thermal cycles.

Long Thermal Cycling:

Performing accelerated thermal testing, we ensure that the antenna can withstand the space environment throughout its entire lifetime with the expected performances.

Power Handling Test:

This ensures the antenna can handle high power levels without performance degradation.

RF Leakage Test:

If the antenna is equipped with a test cap, we perform a radio frequency leakage test to ensure no unintended emissions occur during the integration phase to protect the operator.

Final Functional Test:

S-Parameters, radiation pattern measures and a final rigorous visual inspection are conducted to ensure every parameter meets our demanding standards.

Step 1Initial Functional Test:

To guarantee optimal performance in space, we carry out intricate measurements of the radiation pattern and the S-parameters. By evaluating the antenna’s primary functionality under diverse conditions, we can confidently vouch for its operational consistency in various space environments.

In terms of testing resources, Anywaves relies on the following equipment:

Keysight N9918A FIELDFOX HANDHELD Microwave Analyzer: Vectorial Network Analyzer, 26.5 GHz max. frequency

Step 3Vibration Tests:

To authentically replicate the tumultuous conditions during launch, our antennas undergo rigorous vibration tests, including both quasi-static acceleration and random vibrations. This prepares them for real-world scenarios like engine combustion instabilities and sound pressure levels that induces random vibrations on the fairing’s payloads.

Tests conditions :

Quasi-static acceleration test :

Performed on 3 axis

Load	50 g at 100 Hz

Step 5Vacuum Thermal Cycling:

Space is an environment of extremes. By replicating the vacuum conditions of space, this test ensures the antenna’s consistent performance across varying thermal cycles, ensuring reliability when it matters most.

Tests conditions :

Temperature range	-120°C / + 120°C
Temperature tolerance	Hot case 0°C/+4°C, Cold case -4°C/0°C
Number of cycles	8

Continuing monitoring of the S-parameter of the antenna and its Test-Cap are done during the thermal cycling.

Step 6Long Thermal Cycling:

By conducting accelerated thermal testing, we can vouch for the antenna’s ability to endure the rigorous space environment throughout its entire operational lifetime without compromising on its expected performances.

Tests conditions :

The recurring temperature fluctuations can induce thermal fatigue, ultimately culminating in product failure after numerous thermal cycles. To conduct accelerated life testing, the product can be subjected to cycles of elevated and reduced temperatures that surpass its typical operating temperature range. The thermal cycling testing parameters depend on mission lifetime and thermal conditions on-orbit. These are calculated based on Norris-Landzberg & Arrhenius models and thermal simulations. Typical testing parameters are given below.

Step 8RF Leakage Test:

When equipped with a test cap, our team conducts a meticulous radio frequency leakage test. This assures that the antenna remains faultless and no unintended emissions, potentially harmful in space missions, occur.

Tests conditions :

For emission’s antennas, RF leakage are measured in order to be sure that the operators are safe when the entire RF chain is tested through the Test-Cap. The aim of this test is to be sure that the RF leakage is below the recommendation on the limitation of exposure of the general public to electromagnetic fields (0 Hz to 300 GHz) [1999-519-CE] to ensure the safety of our customers.

Step 9Final Functional Test:

Our commitment to quality culminates in this step. A thorough visual and functional examination ensures that every aspect of the antenna aligns with our stringent standards, promising unparalleled performance in space.

We also perform another measurement of the parameters S to be sure that the results are conformed to the ones obtained during the Initial Functional Test.

Acceptance Tests

According to the ECSS, the acceptance tests are way lighter than the qualifications tests. They ensure that there were no problems during the assembly of the antenna and that its integrity wasn’t compromised.

S-parameter Test:

Initial S-parameter tests serve as a baseline for all subsequent tests.

Random Vibration Test:

To simulate launch conditions and ensure structural robustness.

Thermal Cycling:

A thermal cycle ensures the antennas can withstand temperature fluctuations.

Final S-parameter and Visual Inspection:

To validate that the antennas meet all functional and visual specifications.

Step 1S-parameter Test:

Step 2Random Vibration Test:

To authentically replicate the tumultuous conditions during launch, our antennas undergo rigorous vibration tests. This prepares them for real-world scenarios like engine combustion instabilities and sound pressure levels that induces random vibrations on the fairing’s payloads. It also allows to check the mechanical integrity of each flight model.

Tests conditions :

Acceptance random vibration only is performed on 1-axis at 17,7 gRMS for 60 seconds. For Qualification tests conditions, please refer to the dedicated section.

Step 3Thermal Cycling:

Verifying the antenna’s resilience against temperature fluctuations in space, we conduct a controlled thermal cycle.
