摘要
Abstract
The satellite navigation system consists of a satellite constellation transmitting navigation signal,a ground segment for monitoring the constellation and for disseminating the navigation messages through the navigation signals to the user receivers.The ground segment is consisting of control centers,sensor stations and Up-link stations,interconnected with global communications networks,which need to fulfill strict quality of service (QoS) requirements in terms of availability and latency.This paper will present the results of simulations using OPNET simulation tool,in order to determine the factors impacting the QoS requirements and capacity of these global communications networks.Under the work presented,a frame relay only network and a mixture of frame relay and very small aperture terminal (FR&VSAT) satellite network have been simulated.Performance analyses have been carried out in order to determine whether to communicate with or without prioritized data.关键词
