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. Ron
Operating Environment and Use Urban environment Heat Controlled by soldier with limited experience Fly autonomous and transmit video
System Block Diagram
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 Ron
Video Transmission System New System Choice of Frequency (440 Mhz): Choice of Transmitter (2 watt) Choice of Antenna Meeting FCC Regulations FCC allows transmit power of up to 50 watts on 440 MHz Ron
Video Transmission System Ron
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 Ron
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 Ron
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 Ron
