Tag, You’re It

Popular Science - - CHARTED -

WHEN IT GOES LIVE LATER this year, ICARUS will have two main com­po­nents: an­ten­nae de­ployed on the In­ter­na­tional Space Sta­tion and the tags. The penny-size tech—at­tached as back­packs, col­lars, or ear tags—in­cludes a trans­mit­ter, GPS mod­ule, ther­mome­ter, ac­celerom­e­ter, mag­ne­tome­ter, recharge­able bat­tery, and so­lar cell. The ISS will pick up tiny sig­nals from the tags each time the sta­tion passes over, an ar­range­ment in­spired by ra­dio as­tron­omy, which uses large an­ten­nae to pick up faint sig­nals. Re­searchers can re­motely re­pro­gram the tech.

Pe­tite Pack At 0.59-by-1by-0.35 inch, the new tag doesn’t bur­den this Eurasian black­bird.
