SMLab carried out the electromagnetic compatibility (EMC) analysis of the wireless sensors integrated into a launch vehicle (Vega-C class), verifying that they do not generate electromagnetic interference (EMI) able to compromise the launcher's vital electronic systems.
Electromagnetic compatibility is essential so that onboard systems — from telemetry to communication antennas — can operate together without mutual interference, in an environment characterised by rapid temperature changes, intense vibrations and strong electromagnetic fields generated by the rocket engines.
Approach
- Emission modelling: simulation of the radiated and conducted emissions of the sensors with an electromagnetic simulation platform (SIMULIA), predicting their behaviour within the launcher's complex operational environment.
- Interference prediction: identification of potential interference points before launch and verification of compliance with international EMC standards and safe emission limits.
- Critical phases: attention to launch and stage separation, where the risk of interference increases due to the high power involved.
- Validation: field measurements to validate the simulation results, protecting telemetry antennas, communications and tracking systems even under stress conditions.
The objective was to ensure that all launcher systems operate in synergy — protecting both the vehicle's electronics and ground infrastructure — as a key element for the safety and success of the mission.
