A novel approach for optimal trajectory design with multiple operation modes of propulsion system, part 2
Taheri, Ehsan; Junkins, John L.; Kolmanovsky, Ilya +1 more
Equipping a spacecraft with multiple solar-powered electric engines (of the same or different types) compounds the task of optimal trajectory design due to presence of both real-valued inputs (power input to each engine in addition to the direction of thrust vector) and discrete variables (number of active engines). Each engine can be switched on/…
Pattern recognition in time series for space missions: A rosetta magnetic field case study
Glassmeier, K. -H.; Richter, I.; Ostaszewski, K. +4 more
Time series analysis is a technique widely employed in space science. In unpredictable environments like space, scientific analysis relies on large data sets to enable interpretation of observations. Artificial signal interferences caused by the spacecraft itself further impede this process. The most time consuming part of these studies is the eff…
