Abstract: Placing a satellite or any other spacecraft in orbit is a risky and expensive process; years of research and a lot of money are transformed into equipments that will be beyond any possibility of maintenance in case something goes wrong. Therefore, space projects must be carried on as carefully as possible in order to guarantee that satellite equipments perform its mission properly. In...

Simulation technology is becoming increasingly crucial in the design and optimization of satellites due to the difficulties in testing and verifying system parameters on the ground. Computationally tractable and accurate methods are required in order to test satellite parameters in the complex and dynamic space environment. Although various satellite teams have developed simulation tools, many ...

This paper presents the evaluation performance of a hybrid satellite constellation network which provides internet access based Transport Control Protocol (TCP). The evaluated satellite network uses the constellation topology operating on Low Earth Orbit (LEO). The COMMStellationTM satellite system implemented using network simulator 2 (NS-2). In this paper, we modified a congestion window cont...

Abstract. Seasonal transitions in Arctic sea ice, such as the melt onset, have been found to be useful metrics for evaluating ice climate models against observations. However, comparisons of onset dates between and satellite observations are indirect. Satellite data products rely on observed brightness temperatures, while do not currently simulate must therefore define with other modeled variab...

Title of thesis: ROBOTIC SIMULATION OF FLEXIBLE-BODY SPACECRAFT DYNAMICS IN A SATELLITE SERVICING TESTBED Justin Cory Brannan Master of Science, 2014 Thesis directed by: Dr. Craig Carignan Department of Aerospace Engineering Satellite failures that once led to end-of-life may eventually be addressed using robotic servicing platforms. The ability to model and simulate the physical interaction be...
