"Cyber-security and resilience of satellite infrastructures in the new space era".
Conferral summary
De aller fleste satellitter trenger en antenne. Når satellittene blir mindre, må også subsystemene bli mindre – inkludert antennene. Men hvordan gjør man det når antennestørrelsen egentlig styres av fysiske bølgelengder? Dette arbeidet viser hvordan man kan kombinere mekanikk og elektronikk for å utvikle nye antenneløsninger for små satellitter.
Main research findings
This work presents a development process for small spacecraft antennas. By adapting a rapid-prototyping approach, the project shows what worked, what failed, and what was learned along the way. The result is a deployable, spring-based conical antenna that operates over a wide frequency range. Through repeated testing and refinement, the design was matured into a robust solution, featuring a novel structure and feed, with parts of the electronics integrated into the carbon-fibre spring. The antenna was put through a series of environmental tests to simulate launch and the space environment, and it survived without any degradation. The antenna can be tailored to different missions and helps fill a gap in mature broadband UHF technologies for small spacecraft.
