Publikováno v: Sensors, Vol 20, Iss 14, p 4041 (2020)

Individual spacecraft manual navigation by human operators from ground station is expected to be an emerging problem as the number of spacecraft for space exploration increases. Hence, as an attempt to reduce the burden to control multiple spacecraft
