No. 1 　　Determine the surface point position, shape and size of the Earth and the Earth gravity field measurements. Including triangulation, precision wire measurement, level measurement, astronomical surveying, satellite geodesy, gravity measurements and geodetic calculations. Task is to (1) for topographic mapping and measurement of large projects to provide basic control of plane and elevation; (2) for space science and national defense building accurate coordinate points, distance, azimuth and the Earth gravity field value; (3) to study the Earth's shape and size, such as crustal movement and earthquake prediction information.

Including triangulation, precision wire measuring, leveling, astronomical measurements, satellite geodesy, gravimetry and geodetic calculations. Tasks are: (1) provide basic plane and vertical control of large-scale topographic mapping and engineering survey; (2) for the space science and national defense construction provide precise point coordinates, distance, azimuth and the Earth's gravity field values; (3 ) for the study of the Earth's shape and size, crustal movement and earthquake forecasting to provide information. 　　Used to solve discipline problems geodesy and precision measurements over large areas to build the plane and elevation control network carried out. When measuring, you should generally take into account the Earth's shape, size and gravity field factor. It is the basic means of establishing national and regional geodetic control network, and it is the basis of topographic survey and various other engineering survey work, and for the study and determination of the shape and size of the Earth, space target coordinates and orientation, as well as provide information on crustal deformation. Its horizontal control network, usually with triangulation, trilateration, corner measurement, precision measurement and space geodesy wire build, and with astronomical measurements and gravity measurements, observations are usually imputed to the Earth ellipsoid, calculate the points The geodetic coordinates, and finally through the map projection translated into Cartesian coordinates, as the basic control plane; vertical control network, the general standard of measurement used to establish, to determine the normal high points as the elevation of the basic control.
