Abstract:

The difference between true position and that found by double integration of accelerometer output may be expressed as a function of accelerometer misalignment and platform drift. A method is discussed for estimating errors which is based on a comparison between the results of double integration of accelerometer output and positions as observed by ground based instrumentation. The effects of errors in ancillary equipment are discussed and tables of accelerometer errors have been computed for a typical Black Knight trajectory. It appears that the accuracy of the ground equipment at present available at Woomera is barely adequate to meet the requirements of the experiment.
