4.1.3.GPS Control network design principles
1) In order to ensure the continuous tracking and observation of satellites and the quality of satellite
signals, GPS outlets should be set up in a wide field of view, and the height angle of obstacles in the
field of view should not exceed 15 degrees.
2) In order to reduce or avoid the interference of electromagnetic to satellite signals, the measuring
station should be far away from high-power radio sources (such as TV stations, radios, microwave
stations, etc.), and there should be no objects that strongly reflect satellite signals (such as large
buildings) nearby.
3) The control point should be selected in a place with convenient transportation, stable ground
foundation, easy point storage, and conducive to the expansion of other measurement methods and
joint measurement.
