A Model for Predicting Propagation-Related DSCS (Defense Satellite Communications System) Margin Requirements

Abstract

This technical report describes an analysis of the performance allocations for a satellite link, focusing specifically on a single-hop 7-8 GH link of the Defense Satellite Communications System (DSCS). The analysis is performed for three primary reasons: (1) to re-evaluate link power margin requirements for DSCS links based on digital signalling; (2) to analyze the implications of satellite availability and error rate allocations contained in proposed MIL-STD-188-323, 'System Design and Engineering Standards for Long Haul Digital Transmission System Performance;' and (3) to standardize a methodology for determination of rain-related propagation constraints. The aforementioned methodology is then used to calculate the link margin requirements of typical DSCS Binary/Quaternary Phase Shift Keying (BPSK/QPSk) links at 7-8 GHz fo several different earth terminal locations. Keywords include: DSCS; Propagation prediction; and SHF Static Margins.
