Overview

The General Dynamics SATCOM Technologies lightweight 1-meter flyaway backpack is a motorized auto-acquire antenna designed for worldwide auto-acquisition transmit/receive operation in X, Ku and Ka-band. This antenna consists of a segmented High Pressure Composite reflector and motorized positioner mount. The backpack configuration results in a light-weight and highly portable antenna product. The unique optical shape and accurate composite reflector surface provide superior sidelobe and excellent crosspolarization performance. Repeatability is maintained with precision registration of the nine-piece reflector segments and RF components. The antenna can be quickly assembled by one person in less than ten minutes. The auto-acquire controller can find and optimize for the correct satellite with the push of a button. The antenna controller is configured with an IP-based intuitive GUI and may be configured prior to deployment.
