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 BinaryQuaternary Phase Shift Keying BPSKQPSk links at 7-8 GHz fo several different earth terminal locations. Keywords include DSCS Propagation prediction and SHF Static Margins.
