Operate at 900 MHz Omni-directional and electronic beam-
steering modes Autonomous and manual input beam-
steering Interface with existing architecture Fit on roof of chase van
Project Overview
Primary Receive desired angle from Mobile Control Station
(MCS) and steer relative to van orientation Secondary
Use signal quality feedback from transceiver to finely adjust angle using control law
Tertiary Track and maintain communication link with
multiple aircraft

Power System Overview
12 V DC Battery Wall mounted power supply
Converts 120 V AC to 15 V DC Linear Regulators
Converts 12 V DC to 3.3 V and 5 V Snubber circuits and TVS diodes offer
protection and reliability
Power System
5 V linear regulator sources at maximum 3 A Traces are thicker and wider to handle current
Regulators operate over range of input voltages Battery voltage will decrease over time
Regulators supply necessary current
Design Considerations
Snubber Circuits Regulate ground potential Zener provides clamping Ground bounce PDN droop
TVS Diodes Can dissipate up to 3 kW Begins to conduct in less than 1 ps ESD
