Four Survey-Type Programs for Use with a Programmable Pocket Calculator (HP-65)
Abstract
Four programs for use with an HP-65 programmable pocket calculator are presented. The programs perform survey-type computations: Program 1 computes grid coordinates of an unknown point (a target or the point-of-impact of a round) based on the intersection of all pairs of azimuth rays from three known observation points to the unknown point; Program 2 is similar to Program 1 but uses only two observation points and computes grid coordinates to a higher degree of accuracy than Program 1; Program 3 computes grid coordinates of an unknown point given distance, azimuth and slant angle to a known point-data which can be obtained using a laser range finder on a mount which provides a readout of azimuth and slant angle; Program 4 computes range and azimuth from point A to point B, two known points. The programs were designed to provide an in-the-field data processing capability for experimenters conducting mortar and artillery indirect fire experiments, but can assist Army survey teams in preparing 'Trig.' lists of target grid coordinates in an impact area, or in providing flash support to mortar or artillery units undergoing training tests. As formatted, the programs can be used only with one calculator, the HP-65. With suitable modifications, other calculators might accept the programs, and programs similar in nature to these might find application by other users.
