2. Problem Statement
Problem Statement  
Current UAV technology is not capable of launching vertically using a rail launch system into the atmosphere.  As such, current UAV’s are not suitable for use for urban operations as they must be launched away from the urban setting due to obstacles. This presents problems for certain missions that could be assisted by UAV technology.

3. Operating Environment and Use
Urban environment
Heat
Controlled by soldier with limited experience
Fly autonomous and transmit video

5. Video Transmission System
Last Year’s System:
Transmitted on 2.4 GHz at 1 watt
Could not reach the full 1 mile
Highly prone to interference
Did not meet FCC regulations for ATV

8. Video Transmission System
Plans for Testing:
Test with just video transmitter and computer TV capture card
Test with just video transmitter and down-converter
Test with down-converter and IF converter
Full system test:
Range tests (transmitter and receiver placed at different distances)
Interference tests (transmitter and receiver placed across buildings)
Tests performed with various antenna design iterations

9. Power System Last Year’s System: 1400 mAh NiCad Battery
The DC‐DC converter is fed by the avionics battery and supplies appropriate voltages to on‐board avionics equipment (5V and 12V).
1400 mAh NiCad Battery
Weight=156g+183g+30g=369g
Approx run time=30 Minutes

10. Power System New System Design: 2350 mAh 14.8V Lipoly Battery
Two switching regulators are used to supply both 11V and 5V to the desired systems.
2350 mAh 14.8V Lipoly Battery
Weight=262g+32g=294g
Approx run time=2.15 Hours
