International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / The yawsonde is a device used at the U.S. Army Research Laboratory (ARL) to
investigate the in-flight behavior of spinning projectiles. The standard yawsonde consists
of a pair of solar cells and slits that respond to solar rays. The sun is used as an inertial
reference to measure the pitching and yawing motions of the projectile. An FM telemetry
package transmits the sensor data to a ground receiving station for analysis. The standard
yawsonde package is housed in an M577-type artillery fuse body. The spinning motion of
the projectile serves as the sampling rate for the measurements. When the spin rate is not
significantly higher than the yaw rate, multiple sets of sensors must be used to effectively
increase the sampling rate. The pinhole yawsonde sensor was developed for projectiles
that require multiple sets of sensors in a very limited space. This pinhole yawsonde
consists of a number of sensors located behind pinholes placed around the projectile's
circumference. Since each pinhole makes a yaw measurement, many measurements, or
samples, are taken with each projectile spin revolution. More pinhole sensors may be
added to increase the measurement sampling rate. One application of this yawsonde is to
aid in evaluating the performance of tactical devices and inertial systems onboard
projectiles with limited space for instrumentation.
