Ray-Optics-Based Signal Strength Prediction Method for the Earth-to-Satellite Propagation Model with Meteorology (ESPM2) in the Advanced Refractive Effects Prediction System
Abstract
The Advanced Refractive Effects Prediction System (AREPS) was initially developed as a performance assessment and system analysis tool for the U.S. Navy radar systems operating in the 100- to 20-GHz frequency range. Recently, under majority funding from ONR, AREPS capabilities have been extended to include high frequency (HF), 2- to 30- MHz point-to-point and coverage predictions that support military communications systems and a three-dimensional ionosphereic ray tracing capability for research oriented and HF system design applications. SPAWAR Systems Center San Diego (SSC San Diego) recently developed a medium-frequency (MF), 300-kHz to 2MHz prediction capability for coverage analysis in the amplitude modulation (AM) radio band. With these additions, SSC San Diego, has extended the AREPS usable prediction frequency range from 300 kHz to 57 GHz and has added significant communications system analysis capability. This report describes the latest efforts to extend the range of AREPS applications to earth-satellite communications. The new capability will be called Earth-to-Satellite Propagation Modelwith Meteorology (ESPM2) and will employ a ray of optics propagation tool, including available meteorological/refractivity data, to predict signal strength at satellite locations.
