摘要

The paper discusses specifics of operation, data processing algorithms and results of a test survey for the strapdown gravimeter GT-X. The tests survey was done on board a sailboat, with four repeat lines. The tests goals were to check capabilities of the instrument in the airborne and marine operation modes in conditions similar to that of the industrial surveys. The key role in improving the accuracy of a strapdown gravimeter is played by the quality of calibration, which has a direct influence on the quality of vertical alignment. With the gravimeter mounted onboard, before and after sailing, special inclination experiments were done to estimate the calibration parameters. Gravity was obtained both in the marine and airborne modes. Low vertical alignment errors and low repeat line gravity errors provide some hope for commercial success of the instrument.
