Abstract

Ground vehicle gravity survey is a mature method for census and local encryption survey of the Earth's gravity field. Nevertheless, Previous dynamic gravity measurement methods heavily depend on GNSS information, greatly limiting the implementation areas and measurement efficiency of gravity surveys. To address the aforementioned issues, we introduce a novel SINS/DR/BALT vehicle gravity measurement approach and demonstrate its effectiveness through a single-line sports car test. The results show that the accuracy of SINS/DR/BALT method is equivalent to that of SINS/GNSS method.
