The LaCoste and Romberg gravimeter platform constitutes a complete inertial navigation system and can provide navigational information for marine gravity surveys. Potential applications include: (1) Inertial input to an integrated navigation system using Kalman filtering techniques to utilize all available navigation data; (2) provision of a relatively low cost back-up system to provide navigation continuity in the event of a failure in the primary navigation; and (3) primary navigation in regions not served by long-range systems such as Loran C and beyond the range of short-range systems.
