| Abstract: | According to requirements of marine gravity survey for gravimetry, a strapdown marine gravimeter named SAG-2M is developed, of which the system structure, working principle, features and data processing flow are discussed.And the system precision is evaluated based on some marine gravity survey which is carried out lately.Results showes that the differences of repeat survey lines are quite small, and the crossover differences is about 1.2mGal, demonstrating that the system could meet the specifications of marine gravity survey |
