Abstract

The invention discloses a high-precision baseline measuring and phase correcting method. According to the method, when high-precision baseline measurement is carried out, a sign on an antenna with a multi-path restraining effect is enabled to point north through pointing of a compass, and two antennas of a base line receive global position system (GPS) signals, and acquire original observation data (RINEX). A baseline solution is carried out through the method of adopting an absolute phase correcting mode to carry out phase correction on the GPS original observation data, and a high-precision baseline solution is obtained. The high-precision baseline measuring and phase correcting method can be applied to a nuclear power plant secondary net, a precise engineering net and other high-precision GPS measurement, and is large in practicality.

Description

High precision base measurement and phase correction method
Technical field
The present invention relates to the disposal route of GPS base measurement and observation data, relate in particular to a kind of baseline calculation method of antenna phase center offset correction.
Background technology
GPS is the of new generation Aerospace Satellite navigation positioning system of the seventies in 20th century by U.S. land, sea, and air joint research and development, last 20 years, expensive 20,000,000,000 yuan, built up in 1994 comprehensively, have the new generation satellite navigation positioning system of carrying out comprehensive real-time three-dimensional navigation and station-keeping ability in sea, land and sky.GPS is with distinguishing features such as round-the-clock, round-the-clock, high-precision automatic, high benefits, win vast mapping operations person's trust, and it is multidisciplinary successfully to be applied to the navigation of geodetic surveying, engineering survey, photogrammetric measurement, delivery vehicle and control, earth movement monitoring, engineering project deformation monitoring, resource exploration etc., the technological revolution that has brought a field depth to carve to survey field.But be subjected to the influence of various factors in the gps signal communication process, as ionosphere delay, tropospheric delay, also can be subjected to various adverse effects in the GPS receiver receiving course, because the influence of manufacturing process and other factors can cause gps antenna phase center and antenna geometrical center to be offset, observe gps data and comprise various errors thereby make, increase the difficulty of data processing, also made the GPS bearing accuracy reduce.And the deviation of antenna phase center and variation are for the GPS precision positioning, be difficult to utilize difference method to eliminate or weaken, thereby we utilize the antenna phase center correction model to revise, utilize revised data to carry out data processing, can access more accurate base-line data, increase the accuracy and the reliability of GPS location achievement.
Summary of the invention
Therefore, the objective of the invention is to utilize the antenna phase center correction model to revise, utilize revised data to carry out data processing, obtain more accurate base-line data, increase the accuracy and the reliability of GPS location achievement.
So, the invention provides a kind of high precision base measurement and phase correction method, may further comprise the steps:
The a.GPS receiver receives gps signal, obtains original observed data;
B. utilize existing absolute phase calibration model that original observed data is carried out phase correction, the observation data after obtaining proofreading and correct;
C. utilize the observation data after existing commercial gps data process software is handled correction, separate thereby obtain high-precision baseline.
Wherein, when carrying out the GPS measurement, the mark that will have on the antenna that suppresses multipath effect by compass point refers to north.
Wherein, for obtaining high-precision base measurement data, the GPS receiver is placed on the pressure centering pedestal of observing on the pier.
The advantage of this method is: at the original observed data of obtaining, detect the phase deviation of gps antenna by the relative phase correction model, to the raw data correction of be correlated with, and then carry out the baseline processing.For improving precision, GPS receiver of the present invention needed to regulate having the gps antenna that suppresses multipath effect by compass before receiving satellite signal, make the equal energized north direction of its mark, and the GPS receiver is installed on the pressure centering pedestal of observing on the pier, to reduce the influence of the error of centralization, the observation pier also can weaken the influence of multipath effect to a certain extent.
Consulting the accompanying drawing of the accompanying description embodiment of the invention, is very easily with describing the present invention afterwards in detail.It is limitation of the present invention that accompanying drawing can not be understood as with relevant description, and characteristics of the present invention are limited in claims.
Description of drawings
Fig. 1 settles sketch for GPS receiver of the present invention.
Fig. 2 is a gps data processing flow chart of the present invention.
Embodiment
Below in conjunction with accompanying drawing embodiments of the present invention are further specified:
As shown in Figure 1, GPS receiver 3 is mounted on the pressure centering pedestal of observing on the pier 12, forces the centering pedestal can reduce the influence of the error of centralization significantly, and the observation pier can weaken the influence of multipath effect to a certain extent.After the GPS receiver was installed, the mark that needs to use 4 pairs of compass will have on the GPS receiving antenna that suppresses multipath effect referred to that north is directed, to weaken the phase place off-centre of antenna, makes model can proofread and correct the antenna phase eccentric error preferably.
Be illustrated in figure 2 as gps data processing flow chart of the present invention, after top each preliminary work, each GPS receiver receiving satellite signal, obtain original observed data (RINEX), detect the phase center deviate that corrects receiving antenna by the absolute phase correction model then, obtain pretreated data (RINEX), by relevant gps data the poster processing soft, resolve pretreated data, and then can obtain the degree of precision observation base and separate data.
By above processing, we can weaken the influence of gps antenna phase center deviation to positioning result to a great extent, solve the antenna phase center deviation and be difficult to the difficult problem eliminated with difference method, in high precision GPS measurements such as the secondary net of nuclear power station, precision engineering net, has practicality widely.
The present invention described herein is easy to change on specifically described content basis, revises and/or replenishes, and is understandable that all these change, revise and/or additional all being included in the spirit and scope of foregoing description of the present invention. ]?
