1 General
1.0.1 To unify the satellites positioning survey technical requirements for railway
engineering, and to ensure that the quality of survey results meets the
requirements of survey design, construction, operation and maintenance, this
Specification is developed.
1.0.2 This Specification is applicable to the satellites positioning survey of new
and reconstructed railway engineering.
1.0.3 Prior to the implementation of the satellites positioning survey of
railway engineering, according to the project characteristics, precision
requirements, survey area, and existing data, the technical design of
control network shall be carried out.
1.0.4 The satellites positioning survey receivers and accessory
equipment for railway engineering shall be checked regularly according
to the provisions, and regular maintenance and preservation shall be
carried out, to ensure the normal working condition of the instruments
and equipment.
1.0.5 The satellites positioning survey of railway engineering must strictly
comply with the relevant confidentiality provisions and do a good job of
confidentiality.
1.0.6 In addition to complying with the provisions of this Specification, the
satellites positioning survey of railway engineering shall also conform to the
provisions of the relevant existing compulsory national standards.
2 Terms
2.0.1 Baseline
The vector between two survey points calculated from simultaneously-observed
carrier phase data.
2.0.2 Observation session
The time interval between receiving and stopping receiving satellite’s signal at
a survey station for continuous observation is called the observation session,
“session” for short.
2.0.3 Simultaneous observation
Simultaneous observation of a group of satellites by two or more receivers.
2.0.4 Simultaneous observation loop
A closed loop consisting of the baseline vectors obtained by simultaneous
observation of three or more receivers.
2.0.5 Independent baseline
The baseline determined by independent observation session is called the
independent baseline. When any m receivers observe simultaneously, only the
m-1 baseline is an independent baseline.
2.0.6 Independent observation loop
A closed loop consisting of the independent baseline vectors obtained by non-
simultaneous observation, “independent observation loop” for short.
2.0.7 Free baseline
The baseline which does not belong to any closure condition of non-
simultaneous graphics.
2.0.8 Broadcast ephemeris
The radio signal transmitted by a satellite carries a message signal which
forecasts the satellite orbital parameters within a certain period of time.
2.0.9 Precise ephemeris
The precise orbit information of navigation satellite determined by a network of
global or regional navigation satellite tracking stations.
3 Coordinate system and time
3.0.1 When the broadcast ephemeris is used in satellites positioning survey, the
World Geodetic System (WGS-84) shall be used as the coordinate system. The
basic parameters of terrestrial ellipsoid and the main geometric and physical
constants of the geodetic coordinate system are given in Appendix A of this
Specification.
When the precise ephemeris is used in satellites positioning survey, the ITRF
YY International Terrestrial Reference Frame of the corresponding epoch shall
be used as the coordinate system. When converted to geodetic coordinate
system, the same basic parameters of terrestrial ellipsoid and the main
geometric and physical constants as those of WGS-84 can be used.
3.0.2 When the coordinates of Xi’an Coordinate System 1980 or Beijing
Coordinate System 1954 or National Geodetic Coordinate System 2000 are
needed, they shall be obtained through coordinate conversion. The basic
parameters of reference ellipsoid of the three coordinate systems shall conform
to the provisions of Appendix A.
3.0.3 When needing the coordinates of construction coordinate system or other
independent coordinate systems, the following technical parameters shall be
provided.
1 Reference ellipsoid and basic parameters of survey area;
2 Longitude value of central meridian of survey area;
3 Mean height anomaly in survey area;
4 The height of mean height-level of engineering or survey area;
5 Starting point coordinate and initial azimuth;
6 Vertical and horizontal coordinate addition constant.
3.0.4 When the geodetic height of survey point obtained by satellites positioning
survey is converted into National Height Datum 1985, according to different
precision requirements, a certain number of grade leveling points can be in
connection survey, and the appropriate mathematical model can be used for
calculation.
