Beschreibung:
Mathematical Geodesy
Elements of spherical trigonometry: sphere, small circles, great circles, spherical two-angle, spherical triangle, funda-mental laws in the spherical triangle, Delambre’s and Napier’s equations, first and second Napier’s rules, differential equations, application examples. Reference ellipsoid: ellipsoid parameters, latitudes, curvature radii. Three-dimensional geodesy: 3D ellipsoidal coordinates, 3D geocentric Cartesian coordinates, coordinates in the local geodetic and astronomical system, coordinate transformations, observation equations in three-dimensional geodesy, differences between natural and ellipsoidal coordinates. Geodesic curve on the rotational ellipsoid: normal section and geodesic curve, mathematical description of the geodesic. Azimuth and angle corrections, distance corrections. Direct and inverse geodetic problems: computations of length and azimuth of a geodesic, computation of ellipsoidal coordinates. Geodetic mapping of the ellipsoid surface onto a plane: general relationships, mappings of major importance (Mercator, Gauss-Krüger or Transverse Mercator, UTM); mapping equations, magnification or point scale factor, meridian convergence, direction and distance correction; other mappings. Geodetic reference systems: comparison of different datums, transformation equations and transformation parameters.
Physical Geodesy
Gravity and gravity potential, parameters of the normal gravity field, computation of normal gravity.
Height systems (dynamic, orthometric, normal), vertical datum. Disturbing quantities in the earth’s gravity field: gravity disturbance, gravity anomaly, deflection of the vertical. Geoid determination: astrogeodetic method, gravimetric method, combined methods. Earth models, high resolution gravity field representation.
