LORI: A Multisatellite, Multisystem, Time-Coverage Analysis Program

摘要

It is important to be able to describe the ground-coverage performance of multiple-satellite systems, whether existing or proposed. Measures of delays between sightings of ground targets and simultaneous sightings are useful whether for a single system or between several separate multi-satellite systems. The ground coverage may involve areas, points, grids, or moving targets. The program LORI is designed to handle these problems. LORI (Locater of Repeating Incidents) is a group of programs designed for analysis of effectiveness of satellite systems in coverage of areas of the earth. Its principal features include speed of operation, ease of modification, large capabilities, and simple installation on small or large computer systems. LORI will generate statistics (or specific results) on revisit times and simultaneous coverage for one or two systems of satellites, each system consisting of any number of satellites. These statistics can then be plotted as functions of time, latitude, longitude or other variables. (Author)
