th Generation Flash Ladar system which produces real-time, 3-dimensional (3D) video in all lighting conditions has been demonstrated to be a significant enabler to enhance the mission capabilities of Unmanned Aerial Vehicles (UAVs). These new capabilities include enhanced Intelligence, Reconnaissance and Surveillance (ISR), Automated Target Recognition (ATR), improved situational awareness, GPS denied (terrain relative) navigation, 3D surface mapping, surface change detection (detection of buried improvised explosive devices), camouflage penetration, autonomous aerial refueling and autonomous landing. Ball Aerospace 5 th Generation Flash Ladar system has benefited from over 6 years of development, is compact, modular, and has been demonstrated to be easily integrated and flight-tested on both fixed-wing and rotorcraft with different optical configurations. This paper presents the results of airborne test activities and sample imagery of our 5 th Generation system and discusses options for repackaging and integrating the system into UAV platforms. I. Introduction all Aerospace has significant experience in providing ladar systems for remote sensing applications. NASA’s CALIPSO lidar was built by Ball and has celebrated a number of operational milestones, including an extension of the 3-year initial mission lifetime and over 1 billion laser firings and associated atmospheric measurements. Further, Ball Aerospace is developing the flash ladar navigation system for NASA’s space exploration missions. These programs leverage Ball’s extensive understanding of ladar systems, real time image processing algorithms, guidance, navigation and control algorithms, laser system engineering, and the phenomenology being exploited. 1
