EMI/EMC, Lightning, Space Environment and SEE Design for the Virgin Orbit LauncherOne Vehicle (original) (raw)

2022 IEEE International Symposium on Electromagnetic Compatibility & Signal/Power Integrity (EMCSI)

Abstract

Virgin Orbit has developed the LauncherOne (L1)two stage LOX/RP-1 launch system, capable of deploying payloads up to 300kg to 500km Sun Synchronous Orbit (SSO), and deploying payloads up to 500kg to 200km Low Earth Orbit (LEO).The company has implemented an EMI/EMC Control Program, tailored from RTCA-DO-160F and MIL-STD-461F.Electromagnetic Compatibility (EMC) for LauncherOne has been verified to Launch Range, EGSE (electrical ground support equipment) and internal launch vehicle (LV) Avionics systems electromagnetic environments, by analysis, and tailored, limited component/unit test, subsystem test and limited system level test. The EMISMs (electromagnetic interference susceptibility margins) for interfaces internal to L1 and between L1-747, have been verified by System qualification test, and are 6dB for noncritical and 20dB for critical interfaces. [10] Reports the test methods used to verify functional performance and margins.
