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 5 This presentation is NSLComm proprietary and is confidential

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 1 Gigabit / sec • Capable of providing communications for wide range of frequencies Nano-Satellite 6 This presentation is NSLComm proprietary and is confidential

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 9 This presentation is NSLComm proprietary and is confidential

5m VHTS Antenna Main Characteristics • Surface accuracy better than 0.2 mm RMS • Designed for Multi Beam configuration • Life span equivalent to rigid antennas • Allows for adaptive footprint control • On Board calibration capabilities • Cost target up to 25% of existing solutions 10 This presentation is NSLComm proprietary and is confidential

60 cm LEO antenna solution • 1 Gigabit / sec for LEO satellite • Stowed volume < 2U (2 liters) • Applicable for any LEO satellite • Adheres to the Nano-Satellite (cubesat) standard • Optimal for LEO constellations • Can be used for inter-satellite link • Can be used for LEO2GEO communication Click to see how it works 11 This presentation is NSLComm proprietary and is confidential
