REDUCTION OF ERRORS IN MAGNETIC ASPECT SENSORS BY A SYSTEM OF GROUND CALIBRATION.
Abstract
The report discusses the limitations and sources of error introduced into magnetic aspect sensors when installed in a sounding rocket. Typical values of the errors resulting from the magnetic properties of the rocket and its associated electromagnetic instrumentation are given. An attempt to reduce the errors by pre-flight calibration of the rocket head is discussed, and the techniques employed in the method given. Other methods by which the errors may be reduced are indicated. Results obtained from the ground measurements are presented and from these it is concluded that the procedure allows the magnetometer data to be corrected. so that measurements give the magnitude and direction of the applied field with an rms vector error of less than 0.0005 oersteds.
