Abstract : The average burst point of artillery shells is computed from individual burst-point observations. We review such calculations within the framework of general least-squares averaging of observation in an n-dimensional space and propose an iterative solution for cases where the event scatter is unknown and neither it nor the observational scatters can be neglected. The solution produces the average burst point and an estimate of the event scatter, that is of the expected burst point location and the dispersion of the artillery fire.
