The Problem High throughput satellites, providing large bandwidth,
require large antennas with a very high surface accuracy
• Complexity: Difficult to launch to space
• Weight: Satellite launchers limit current antenna sizes to ~3m
• Accuracy: Expandable antennas are less accurate than rigid ones
Current Status
• Solutions for large VHTS satellites are complex,
heavy and very expensive

Our Solution
A large diameter expandable antenna technology
with an adaptive corrective and pattern shaping sub reflector
This technology transforms the efficiency of communications services
and may disrupt the entire communications industry.
• Performance: Up to 10X (GEO) and 100x (LEO) the throughput of
current solutions
• Cost reduction: Highly cost effective, as opposed to current solutions
• Flexibility: In-orbit footprint control
• Capable of providing communications for wide range of frequencies 1 Gigabit / sec

How does it work?
• Main reflector is compacted during launch and orbit raising
• After Main reflector is deployed, calibration is performed to
achieve required performance
• An onboard measurement system measures main reflector
surface errors due to thermal variations and aging
• The Flexosub shape is changed to compensate for any surface error
• Flexosub is used in order to control the footprint
