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.

The present invention relates to a mass measurement system and method capable of precisely measuring the mass of a sample in a gravity-free environment. The mass measurement system using measurement of frequency shift of a vibrator according to the present invention includes a vibrator vibrating at a predetermined resonance frequency with a mass of a sample added thereto, a frequency counter for measuring a resonance frequency of the vibrator caused by vibration, a standard mass database for storing therein known standard masses and standard mass frequency shifts corresponding to variation in the standard masses, and a main controller for calculating a sample mass frequency shift corresponding to the added sample mass on the basis of the resonance frequency received from the frequency counter, searching the standard mass frequency shifts stored in the standard mass database, comparing the calculated sample mass frequency shift with the searched standard mass frequency shifts, extracting a predetermined standard mass, outputting the extracted standard mass as the mass of the sample, and controlling the entire system. Accordingly, the present invention can precisely measure the mass of a small-sized sample, in particular, an animal sample, in a gravity-free environment.
