Compared with Geostationary Orbit (GEO) satellite systems and Medium Earth Orbit (MEO) satellite systems, Low Earth Orbit (LEO) satellite systems provide lower propagation delay as well as higher throughput. Because of these reasons, LEO satellite systems can play a pivotal role in providing services to areas where there is no substantial terrestrial infrastructure. In this paper, a novel kind ...
Recent technological advances have accelerated a renaissance in usage of non-geostationary (non-GSO) communication satellites in provision of various services domestically and globally. Early ventures into communication satellites have used satellites in low Earth orbits. The main reasons for this mode of operation were that the booster technology was not available to lift satellites into a hig...
Recalling the Palapa domestic satellite system, as a breakthrough technology for assessing isolated areas, and triggering business activities. INTELSAT commenced the opening of new horizons for reliable international satellite communication, and Indonesia took a wise decision to join, notwithstanding its economic hardships. Indonesia, had to take crucial decisions during ITU WARC-ORB ‘85 and ’8...
Next generation satellite systems are ideally suited for multicast and real-time traffic. Therefore, it is highly attractive to offer IP multi-videoconference services over IP multicast enabled satellite systems, combining link efficiency and access to remote areas. ICEBERGS project, presented in this paper, addresses the integration of IP video and IP multicast in EuroSkyWay geostationary sate...
The paper addresses the TCP performance enhancing proxy techniques broadly deployed in wireless networks. Drawing on available models for TCP latency, we describe an analytical model for the latency and the buffer requirements related to the split-TCP mechanism. Although the model applicability is broad, we present and evaluate the model in the context of geostationary satellite networks, where...
Surface albedo is one of the key controlling geophysical parameters in the surface energy budget studies, and its temporal and spatial variation is closely related to the global climate change and regional weather system due to the albedo feedback mechanism. As an efficient tool for monitoring the surfaces of the Earth, remote sensing is widely used for deriving long-term surface broadband albe...
This paper describes the main characteristics and architecture of a satellite mobile internet access (MSIA) system developed by ETRI. MSIA system provides Internet service, broadcasting, and digital A/V service in both fixed and mobile environments using Ku-band geostationary earth orbit (GEO) satellite. A Ku -band two-way active phased array antenna installed on top of the transportation vehic...
This paper addresses key mechanisms for service provisioning in non-geostationary satellite constellations employing intersatellite links (ISLs). To this end, several recent research contributions on ISL routing and signaling, and on satellite diversity and handover are summarized and presented in an integrated manner to show their interplay towards end-to-end service provisioning. The focus wi...
