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

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
