Harmon, William E · Defense Technical Information Center (DTIC) · 1979
This study examines the electronic direction finding problem at division level, and proposes the use of the Texas Instruments Programmable 59 Calculator as an interim solution to the electronic direction finding calculations, currently performed manually at the tactical level. The study provides a calculator program description with programming instructions, detailed instructions for use of the calculator with and without the printer, procedures for input/output, a worksheet for field use, and an operational concept.
