1. NASA ATM Upgrades Present ATM laser system Laser 100 uJ/pulse 5000 Hz 4 nsec pulsewidth System 20 Hz scanner PMT detector Improved ATM laser system Laser 500 uJ/pulse 10000 to 50,000 Hz 2 nsec pulsewidth System 50 Hz scanner Enhanced detector/telescope System improvements: Denser sampling/ Sub meter sampling across swan width Wider scan capability from altitude (attitude limited) Improved target waveform resolution (narrower pulsewidth)

2. NASA ATM Upgrades Impact on Program- no impact The ATM program maintains two independent Lidar systems. Improvements can be developed on one system and phased to the second ATM system when validated Cost Laser $150 to 200K Scanning System $25 K Detector System $30 K Schedule Phased through 2009

3. NASA ATM MICROLIDAR Proposed development of a small lidar suitable for small aircraft/UAV deployment. Initial development would be a profiling lidar due to limits on UAV attitude determination Automated autonomous operation solid state data system Low power requirement Approximately 1 cubic foot instrument volume

4. NASA ATM MicroLidar Cost Laser $50K Detector System $30 K Data System $20 K Attitude System depends on UAV GPS System depends on UAV Schedule developed 2009 operational 2010 Impact on Program- no impact The ATM MicroLidar can undergo development and testing on current ATM deployments in 2009. UAV integration could begin in 2010.
