Figure 10. Effect of transport on drift rate14
ConclusionThe <strong>CG</strong>3 represents several significant advances in gravity meter design. Its microprocessorcontrolledautomatic reading and data acquisition system overcome many of the operational deficiencies of existinginstruments; extensive use of electronics simplifies the mechanical design and standardizes theproduction process. The test results shown above, which demonstrate the high performance capacity ofthe instrument, and the ease of operation, fully vindicate the design approach.Other features of the <strong>CG</strong>3, such as the electronic tilt compensation and the integrated housing, set newstandards for gravity meter design, and indicate the direction of future developments in the field.ReferencesHugill, A.L., 1984, “The design of a gravimeter with automatic readout”.
