A significant objective the High-Altitude Balloon Experiment (HABE) is to conduct and develop experiments that focus on laser pointing and tracking. The target scoreboard systems is a scoring system that determines pointing accuracy, jitter, and beam drift. It also is designed to potentially provide direct feedback to HABE's payload tracker. In this paper, we describe the system's design, a model of critical parameters, and provide the operation data we have collected to date. The target scoreboard is composed of a marker laser, a portion of the payload's optics, an 11 x 11 photo diode array mounted in the nosecone of a WB-57 aircraft, centroid processing electronics that operate at 2,000 frames per second, telemetry, a global positioning system (GPS) receiver, motion sensors, a digital recorder, and an operator control console. The scoreboard system and design are unclassified. |
