| Abstract: | As focusing on present domestic INS technology and GNSS data processing technology, the feasibility for carrying out inertial gravimetry experiment with domestic inertial navigation system is discussed. The results from the analysis show that, although GNSS observation and data processing have not big issues presently, it is still hard to reach 1×10\+\{-5\}ms\+\{-2\} gravity accuracy by use of the inertial navigation system. However, with the technical progress of the domestic inertial system, the day for inertial gravimetry with domestic inertial navigation system is approaching. |
