2000 National geodetic coordinate system ChinaGeodeticCoordinateSystem2000: CGS2000 is a high-precision, dynamic, practical and unified geocentric coordinate system established by the state, including the origin, the orientation of the three coordinate axes, the scale and the four basic parameters of the earth ellipsoid. Its origin is the mass center of the entire earth including the ocean and atmosphere: the Z axis points from the origin to the direction of the earth's reference pole at epoch 2000.0, which is calculated from the initial direction given by the International Time Bureau at epoch 1984.0. The directional time evolution ensures that there is no residual global rotation relative to the earth's crust. The X axis points from the origin to the intersection of the Greenwich reference meridian and the earth's equatorial plane (epoch 2000.0), and the Y axis, Z axis and X axis form a right-handed orthogonal coordinate system; the scale adopts the scale in the sense of general relativity: the four basic parameters of the earth ellipsoid are the major semi-axis, flattening, gravitational constant and rotation angular velocity. [GB/T17159-2009 Geodetic Terminology 3.80] 3.2 Global Navigation Satellite System GlobalNavigationSatelliteSystem; GNSS is a system that uses global navigation satellite radio navigation technology to determine time and target spatial position. Currently, they mainly include GPS, GLONASS, GALILEO, China's BeiDou Satellite Positioning System (COMPASS), etc. 4 General Principles

4.1.2 The elevation system adopts the normal height system, and the elevation datum adopts the 1985 National Elevation Datum. 4.1.3 The time system shall adopt the Coordinated Universal Time (UTC). If Beijing time is adopted, the time zone difference shall be considered for conversion with UTC. 4.2 Accuracy measurement index

Plane control networks should generally give priority to satellite positioning measurement control networks, and can also be in the form of conventional corner combination networks or wire networks. The layout of the control network follows the principle of hierarchical layout from the whole to the part, from high to low, and allows for cross-level layout. 5.1.3 Grading
The plane control network is divided into second, third, fourth and first, second and 5.1.4 Point accuracy
The point accuracy requirements of the plane control network are as follows: 2

Observation piers can also be built; only pillars can be buried at the third and fourth-level plane control points. 5.1.5.3 When the markers of each level of plane control points are also used as level markers, they should be buried in accordance with the requirements of level markers, and the center of the marker should have an obvious center point.
5.1.6 Density of control points
5.1.6.1 The density of control points of each level should meet the layout requirements of the next level control network in the survey area, and comprehensively consider factors such as mapping methods and mapping scales.
The density of first- and second-level control points should be differentiated by mapping scale, and take into account the complexity of terrain categories. The average number of points per square kilometer 5.1.6.2
(including each high-level control point) should not be less than the requirements of Table 1. When mapping by aerial survey, the density of control points of each level can be separately specified according to the requirements of image control measurement.
