IP Mobile Multicast over Next Generation Satellite Networks. Design and Evaluation of a Seamless Mobility Framework for IP Multicast Communications over a Multi-beam Geostationary Satellite Network
The inherent broadcast nature of satellites, their global coverage and direct access to a large number of subscribers give satellites unrivalled advantages in supporting IP multicast applications. A new generation of satellite systems that support regenerative on-board processors and multiple spot …

Low-cost Wireless Internet System for Rural India using Geosynchronous Satellite in an Inclined Orbit
… to this is providing Internet access using geostationary satellite links, which can prove commercially infeasible in predominantly cost-driven rural markets in developing economies like India or China due to high access cost per user. A low-cost derivative of the conventional satellite-based …

Blind and pointed Sunyaev-Zel'dovich observations with the Arcminute Microkelvin Imager
… to the known antenna geometry and flagging geostationary satellite interference. This is followed by an outline of the software that I have developed to subtract sources from visibilities, concatenate data from multiple observations, simulate data, and perform jack-knife tests to evaluate …

Architecting Optimal (Space) Strategies: A Quantitative Framework
… as well as the expansion of services relying on satellite data. While the barriers of access may be lower, the acquisition of effective space capabilities remains a costly and challenging task for emerging or aspiring space actors. Yet literature on and tools for measuring the outcomes of …

Space radiation environment impacts on high power amplifiers and solar cells on-board geostationary communications satellites
Communications satellite operators maintain archives of component telemetry to monitor system function. Operators generally do not typically use the telemetry data for scientific analysis of the space radiation environment effects on component anomalies or performance. We partnered with four …

Determining ground-level composition and concentration of particulate matter across regional areas using the Himawari-8 satellite
… or twice per day. Sub-hourly, infrared (IR), geostationary data, such as the ten-minute data from Himawari-8, are required to monitor these events to ensure that sporadic dust events can be continually observed and quantified. Newer quantification methods using geostationary data have focussed …

Assessing solar radiation components over the alpine region Advanced modeling techniques for environmental and technological applications.
… optimization strategies. Algorithms based on satellite data can overcome these limitations. They exploit RTM-based look up tables for modeling clear-sky radiation, and derive the radiative effect of clouds from remote observations of reflected radiation. However results strongly depend on the …

Satellite-based Analysis and Forecast Evaluation of Aviation Contrails
… develops an approach to locate contrails in satellite imagery and utilize these observations to assess existing methods for contrail prediction, as well as provide improved short-term forecasts. Contrails are found in geostationary GOES-16 ABI imagery 2by use of a convolutional neural …
