The Drag Augmentation Deorbiting System (ADEO) breaking sail was efficiently deployed from the ION satellite service in late December 2022. A sail space of three.6 sq. meters was autonomously deployed from an impressively small packing dimension of 10 x 10 x 10 cm to show deorbiting satellite expertise.
ADEO’s deployment was captured in entrance of the “eyes” of the built-in digital camera onboard the ION satellite service, as ADEO unfurled displaying its “wings,” and instantly initiated the satellite’s descent—often known as deorbiting. The picture reveals one fringe of the sail—a big aluminum-coated polyamide membrane hooked up to 4 carbon-fiber strengthened booms, following its jack-in-a-box deployment.
The sail supplies a passive methodology of deorbiting by growing the atmospheric floor drag impact and inflicting an accelerated decay within the satellite’s orbital altitude. The satellite will finally burn-up within the environment, offering a faster residue-free methodology of disposal. ADEO gently pushes the ION satellite service, as if it is on “angel wings,” out of its orbit and in the direction of Earth’s environment.
Adeptly named “Present Me Your Wings” the ADEO-mission is the ultimate in-flight qualification check wanted to offer the technological proof-of-concept. A smaller 2.5 sq. meter sail was fitted onto the higher stage of the Electron launch car “Its Enterprise Time” mission in 2018 and several other parabolic flights have been carried out from 2019 to 2022.
The ADEO check mannequin is the smallest variation of the ADEO product household, designed particularly for the de-orbit of small satellites within the 1–100 kg class vary. The method is nonetheless scalable for medium and huge dimension satellites. A number of models, on one satellite or an upper stage can be possibility, if the lodging of a bigger sail is unfeasible.
Tailored options depend upon the preliminary orbit, satellite mass and required de-orbiting time. The biggest variation may be as huge as 100 sq. meters and take as much as 45 minutes to deploy. The smallest sail is simply 3.5 sq. meters and deploy in simply 0.8 seconds.
ADEO expertise supplies a secure, strong and sustainable methodology of passively de-orbiting small satellites. Passive strategies of deorbiting are advantageous in eliminating the necessity for lively steering, with no extra GNC or propulsion subsystem. The system may be designed for passive angle stabilization and the method is relevant for non-operational and tumbling satellites
Reliably eradicating satellites as they method their system end-of-life, or satellites which have turn out to be unresponsive, is a key facet in ESA’s ESA’s Zero Particles Initiative. Worthwhile orbits turn out to be obtainable to be used and the chance of undesirable collision decreases—which might solely create the following technology of space particles.
