An index that well shows the difficulty of ground deployment test is the ratio of gravity torque to deployment torque. The object of this study is to quantitatively clarify the relationship between this index and the accuracy of deployment test. We perform deployment tests using a simple planar truss under micro gravity and gravity environments. Ground tests in which the index value of the truss is increased are also performed. Comparing these test results, we find that the estimation error of the development drive force is 10%, even for the simplest structure whose difficult index value = 1. The accuracy of the deployment drive force predicted from the mean value of gravity direction and the opposite direction results cannot be said to be sufficient even for simple models such as the planar truss. We introduce an empirical equation that sets a linear relationship between the difficulty index value and the evaluation accuracy. We can conclude that it is infeasible to test the ground deployment of structures whose difficulty index value exceeds 1000.
