Ground Terminal Simulator Implementation for Uplink Synchronization Trials

Abstract

A ground terminal (GT) simulator was developed at Defence Research Establishment Ottawa (DREO) as part of an in-house activity examining aspects of uplink synchronization for extremely high frequency (EHF) satellite communications (SATCOM) using frequency bopping. The GT simulator consists of a GT processor, custom interface boards, synthesizer controller, frequency synthesizer, and data source. The GT processor is the principal component of the simulator and is realized by a TMS320C30 digital signal processor board. This report describes the implementation of the GT processor functions relating to uplink synchronization and the interfaces between the various components of the simulator. This report also describes the synchronization procedure for the GT simulator. The procedure is broken down into three steps: downlink synchronization; uplink coarse synchronization; and uplink fine synchronization. A guide on the hardware installation of the various components of the GT simulator and a list of the executable files needed to run the simulator is provided in an appendix.
