An AstroMesh configuration is available for almost every off-set space antenna application. Astro has developed a flight proven family of deployable mesh reflectors capable of excellent RF performance from low frequency (UHF) to high frequency (Beyond Ka-Band) in deployed diameters from 3-meter to 50-meter. Our designs are scalable, inherently stiff, incredibly light with unmatched surface accuracy and free from Passive Inter-Modulation (PIM) which plagues most competitive designs.
The AM/AM-1 class AstroMesh reflectors are designed to cover the range of 6-meter to 25-meter deployed diameters. The AM configuration, used on the Thuraya program, was the first generation AstroMesh designed to mount on top of the spacecraft. The AM-1 refined configuration is designed to stow on the sidewall of the spacecraft with a 40% slimmer stowed diameter than the AM version. These are the workhorses of the AstroMesh family with substantial flight heritage.
AM-Lite is the newest addition to the AstroMesh family. The AM-Lite class reflector is optimized for smaller, 3-meter to 8-meter, deployed apertures. This reflector is extremely light, yet stiff enough to allow RF testing on the ground with minimal off-loading. Our AM-Lite qualification hardware has been RF tested with outstanding performance at greater than 50 GHz.
The AM-2 class AstroMesh is designed for very large reflector application, 18-meter to greater than 50-meters. Our AM-2 configuration stows in a very compact package; essentially the same diameter as an equivalent deployed diameter AM-1, but in 40% less height. This packaging density is achieved utilizing a unique deployment articulation, but still ending with a deployed truss configuration identical to our standard AstroMesh reflectors.
