4.3 Field Static Data Collection
Static survey is mainly used for control point survey. As control points, millimeter
accuracy is required. The standard and requirement of static survey is different from
countries to countries, we suggest doing in the following way:
 At least 3 GNSS receivers are needed, because 3 receivers can construct the
triangular and stable net.
 Make plan and go to the project to make the point mark on the ground.
 For example, 1&2 points are the primary control points, they are the known
points, we want to survey the secondary control points A1, A2, A3, A4 and A5;
firstly mark the approximate position of 1 and 2 in Google Earth, then based on
project request make the mark of points A1-A5 in Google Earth.
