Estimating the performance of telecommunication systems using the ionospheric transmission channel. Ionospheric communications analysis and prediction program user's manual

The operation and use of the Ionospheric Communications Analysis and Prediction Program (IONCAP) is described. The computer program is an integrated system of subroutines designed to predict high frequency (HF) skywave system performance and analyze ionospheric parameters. These computer aided predictions may be used in the planning and operation of high frequency communication systems using skywaves. Instructions for the use of IONCAP are given. A description of the input data requirements, including data definition, organization, and instructions for setup of the various analysis tasks, is presented. Procedures and formats are given for preparing the input data and executing the program. The various outputs are presented and described with an interpretation of the analysis results.
