Aeneas Got Aperture?

Aeneas Got Aperture?

The Aeneas Mission

• Space based tag tracking experiment

− Space implementation of Marine Asset Tag Tracking System

(MATTS) by iControl Inc. − Bi-directional 2.4GHz comm. link

for Wireless Sensor Network − Ultra sensitive receiver to

communicate with low power, small, earth based sensors

− System currently uses ground stations ~ 1 mile range from ports

• Proof-of-concept: Satellite-based receivers for open ocean or cross

country • iControl data format selected for DHS

“Secure Corridors” Program
