Laser inter-satellite links (LISLs) between satellites in a free-space optical satellite network (FSOSN) can be divided into two classes: permanent LISLs (PLs) and temporary (TLs). TLs are not desirable next-generation FSOSNs (NG-FSOSNs) due to high LISL setup time, but they may become feasible next-next-generation (NNG-FSOSNs). Using the constellation for Phase I of Starlink, we study impact o...

The flexibility of mobile wireless ad hoc networks (MANET) and global coverage of satellite communications presented an ideal combination to provide emergency and disaster relief services. This paper presented the concept of a hybrid MANET-satellite network developed in the on optimising hybrid ad hoc and satellite networks (MONET) project funded within the EU 7th Framework Programme (FP7). It ...

This paper summarizes the results of a set of simulations of error control schemes for transmission of ATM cells in Wireless and Satellite ATM networks. For Wireless ATM networks, we consider a scheme which incorporates separate FECs for ATM cell header and payload. This scheme is an effective scheme and achieves a trade-off between coding rate and bandwidth. A concatenated FEC scheme (RSCCC) i...

As an initial step in explorirq~ the opportunities afforded by the merging of sate] lite and terrestrial networks, BcHcorc and JP1. conducted several experiments utilizing Ilellcore’s experimental Personal Communications System, NASA’s Advanced Communications Technology Satellite (ACTS) and JP1,’s ACTS Mobile Terminal. These expcritnents provided valuable information on the appl icat ions, inte...

The convergence between fixed and mobile networks is the new paradigm in the world-wide telecommunications network. Satellites are striving to become an important actor in the Next Generation Networks (NGN) by offering seamless integration with the terrestrial networks. This provides an opportunity to the Satellite industry to advance and adapt this framework to the new DVB-RCS (Digital Video B...

In this paper, we have provided a summary of the design options in Satellite-ATM technology. A satellite ATM network consists of a space segment of satellites connected by inter-satellite crosslinks, and a ground segment of the various ATM networks. A satellite-ATM interface module connects the satellite network to the ATM networks and performs various call and control functions. A network cont...

In a wide variety of broadband applications, there is a need to distribute information to a potentially large number of receiver sites that are widely dispersed from each other. Communication satellites are a natural technology option and are extremely well suited for carrying such services because of the inherent broadcast capability of the satellite channel. Despite the potential of satellite...

Programmable Active Networking is one approach to providing open service engineering for telecommunications and networked services. The overall objective is to provide a platform which may be tailored to provide all the functionality required for many applications. Through the years a number of approaches have been developed, some of which have found substantial success, others are still in the...

This paper discusses the evolution of communication satellite systems and communications satellite technology from the 1960’s to the 1990’s. The paper identifies the key attributes of satellite communications that has driven this evolution and now drives the future directions such systems will take. The paper then discusses the future direction of communication satellite systems including DBS, ...
