Abstract
An accelerometer and rate sensor package to aid gravity gradiometers is provided. The accelerometer and rate sensor package is mounted directly on or within a gravity gradiometer instrument (GGI). Outputs from the sensors can be used to reduce unwanted noise due to angular rotational rates, angular accelerations and linear accelerations that may be coupled to the GGI. Since the sensor assembly is directly mounted on or within the GGI, the sensor assembly is coupled to the GGI and senses the acceleration and angular rates as seen by the GGI. Thus, outputs from the GGI can be corrected more effectively using the sensor assembly's outputs.
