  • Patent number: 10661919
    Abstract: A docking simulator according to an exemplary embodiment of the present disclosure is a docking simulator capable of mimicking docking between two flight vehicles in a zero gravity environment, the docking simulator including: a passive module which is disposed at a preset position; and an active module which performs docking with the passive module by approaching the passive module while performing a translational motion. According to the present disclosure, the docking simulator capable of performing, on the ground, a logic verification test for rendezvous docking between the two flight vehicles in the space in the zero gravity environment is implemented, and as a result, it is possible to perform more various logic verification tests for rendezvous docking by mimicking the rendezvous docking by using actual objects.
