Embodiment Construction
[0075] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0076] Such as figure 1 Shown is the working flow diagram of the gravity anomaly data processing method applicable to the strapdown marine gravimeter of the present invention. The gravity anomaly data processing method of the present invention specifically includes the following steps:
[0077] (1) Define the carrier coordinate system (system b) as the right front upper coordinate system, denoted as ox b the y b z b , the origin is at the center of mass of the gravimeter, x b 、y b and z b Pointing to the right, front and up of the gravimeter respectively. Install the strap-down gravimeter on the measuring ship, and the Y-axis of the gravimeter points to the bow of the ship, that is, forward. At this time, the XYZ axes of the gravimeter point to the right front and upper direction of the ship, as shown in image 3 Shown is a schematic diag...
