8 General Surveying Method

8.1 Surveying Method for GPS

8.1.1 Static Survey

GPS static measurements, is the use of measurement-based GPS receivers to locate a

measurement. Mainly used to create various kinds of control net. Static GPS

measurements carried out that the GPS receiver antenna in the location of the observation

process is static, in data processing, it will be the location of the antenna as a receiver

does not change over time, the amount of change, through the received satellite data to

seek a change in the coordinates of points to be determined. In the measurement, GPS

static measurements of the specific observation model is more than one receiver at

different stations on the static synchronous observation time from 20 minutes to 10 hours

range.Relevant Technical Index

No.s of observation session1.8

Length of observation session: 25 minutes

Valid observation satellite:4 pcs

Geometry pattern strength PDOP6

Data collection interval 15s

8.1.2 RTK Survey

Set up GPS base station on a benchmark. The tripod is erected on the benchmark and

strictly centered. Antenna installed, Input point numbers and coordinates. And at least two

benchmarks shall be surveyed for checking purpose. The two control-benchmarks will be
