| Abstract: | A brief introduction of the current commonly used gravity type and nominal accuracy, and the transport per- formance, gravity segment size, route distance length and the observation time on relative gravity observation accuracy were determined and analyzed, the results show that ： the effect of gravity observation precision and the main factors of automobile transportation tools, choose good off-road performance, good shock absorption effect of the car as complete high grade mobile gravity measurement task prerequisite. |
