AstroMesh®

Unfurlable Mesh Antenna

AstroMesh® The state-of-the-art AstroMesh® unfurlable mesh antenna reflector technology is the most advanced and reliable large aperture deployable reflector available. Apertures can range from 3 to 50 meters in diameter, covering radio frequencies UHF to beyond Ka-band. The AstroMesh® performance record is unmatched with all of its reflectors deploying successfully on-orbit without incident or failure. Flight Heritage 10 units are deployed on-orbit and performing flawlessly. • Thuraya/GEM, 12-m, L-Band
