Human Factors Considerations in Satellite Operation's Human-Computer Interaction Technologies: A Review of Current Applications and Theory [PDF]

open access: yesInternational Journal of Managing Information Technology. 13 (2021) 23-43, 2021
Satellite operations are a subset of remote operations that draw similarities with remotely piloted aircraft (RPA) and uncrewed aerial vehicle (UAV) operations. Increased research into boredom, complacency, habituation, and vigilance as they relate to satellite operations is required due to a lack of prevalence in the literature.
