Abstract

The article introduces a new approach to solving the problem of in-the-field operational determining of systematic error of drop-off a free-fall unguided container by prospective small-class strike unmanned aerial vehicles.

Analysis of the existing techniques of drop points’ coordinates determination of destruction weapons, employed for the manned aircraft, revealed their poor accuracy, which does not allow further performing the effectiveness evaluation of strike unmanned aerial vehicles application while ground targets striking.

Two ways of drop points coordinates determination of a free-fall unguided container were developed. They are based on modification of measuring and resection methods. The first technique realizes the direct measuring method, differing from the other by the sounding signal device application, particularly, a laser measuring device. The second technique is based on the indirect measurement method. Its difference from the resection method consists in the simplified order of measurements realization, and the application of one laser measuring device, instead of three.

The presented work reveals the content and the order of realization of each technique, which allows apply them not only for tests performing, but also while planned flights execution of unmanned aerial vehicles to maintain a high-level proficiency of operators at the ground control stations.

A scientific-methods apparatus for accuracy evaluation, based on comparing a polygon area as well as error theory methods, was developed for determining measuring error of the drop points coordinates of ammunition dummies performed by suggested and well-known methods.

Thus, two new operational techniques for drop points determining of ammunition dummies, being dropped from strike unmanned aerial vehicles, were developed. These techniques ensure two times and more increasing in performed measures accuracy. It will allow increase the efficiency of the systematic error determining for the batch small-class strike unmanned aerial vehicles in the field (combat) conditions.
