3.1 observation period (observationsession) the station starts to receive the satellite signal to stop receiving, and the time interval of continuous observation is called the observation period.

segment.

3.2 geometric accuracy factor [geometricaldilutionofprecision (GDOP)] the amplification factor of the positioning error due to the geometric relationship between the user and the selected constellation. The smaller the GDOP value, the finer the positioning the higher the degree.

3.3 Ultra-baseline (mini-baseline) Refers to the standard length of the standard value in the range of 0.2m ~ 24m.

3.4 RTD measurement (realtimedifferential) Real-time pseudorange differential measurement.

3.5 RTK measurement (realtimekinematic) Real-time dynamic measurement.

3.6 Antenna phase center (antennaphasiccenter) Antenna phase center (average antenna phase center averageofantennaphasiccenter) refers to the microwave antenna Electrical center. The theoretical design should be consistent with the geometric center of the antenna. The difference between the phase center of the antenna and the geometric center is called the antenna.

Phase center deviation.

3.7 World Geodetic Coordinate System 1984 [worldgeodeticsystem1984(WGS-84)] Based on the precision ephemeris NSWC-9Z-2 corresponding to WGS72, the US Department of Defense adopted 1980 large ginseng A geocentric coordinate system established by the test and BIH1984.0 system orientation.

The GPS satellite ephemeris is based on the WGS-84 geodetic coordinate system. The coordinates and relatives of GPS single point positioning
