Year-Round Visibility Limits for Scheduling Yaw Sonde Firings
Abstract
To study the rotational motion of projectiles in free flight, yaw sonde devices are mounted in them to record the motion. Since these devices use the sun's rays to obtain a record, it is necessary to fire test rounds only at times when the sun is in a favorable position. Year charts for three sites (NWC, China Lake, California, Yuma Proving Ground, Yuma, Arizona; and NASA, Wallops Island, Virginia) are shown. From such charts, the most favorable firing times may be chosen for each day in any given year. Range azimuth is the most important factor in determining whether the yaw sonde will see the sun.
