New Space projects require “traditional” Space projects equipment-level testing. Typical testing campaigns for any kind of satellite or subsystem include:
Vibration, Shock Response Spectrum (SRS), Electromagnetic Compatibility (EMC) / EMI, Thermal vacuum (TVAC), TID, Other more specific tests needed for subsystems may include: Optical tests, Electrostatic Discharges (ESD), Materials tests (mechanical, electrical, cleanliness), Magnetic tests

ALTER is performing gamma and proton radiation at various PICs.
The satellite market is experiencing a paradigm shift with the photonics penetration in every part of the satellite payload. Although some advances have been done with the introduction of optical interconnects in a commercial digital processor of a satellite payload

The most relevant result of this work is that all tested samples passed satisfactory the test without relevant changes in the measured parameters, with the exception of one of the WG-EO switches which had a catastrophic failure, as it will be commented later. The pass/non-pass criteria were defined comparing the results of the electro-optical characterization after each test with the corresponding results for each parameter prior to the tests, taking into account the measurement uncertainty.
Lasers endurance characterization in vacuum conditions

Laser diodes characterization can be complex due to the laser’s nature. A good heat dissipation must be provided to avoid lasers being damaged. Unique and challenging equipment is required for a perfect characterization because accuracy is a must with this optical component.
The real challenge? The test setup definition and implementation when lasers must be tested in extreme conditions, like vacuum or high/low temperatures.

SRS shock testing for Small Sats

Shock Response Spectrum (SRS) is intended to reproduce the sudden shock that the satellite experiences when deployed from the launcher. This test consists of placing the EUT on a table and shocking the table with a hammer or projectile. This test is normally applied just to non-qualified designs. SRS is not a complex test, but it is tricky and requires a lot of experience from the operator.
