GPS in Construction Survey Control Network Applications
Bits of information, the data processing to complete the positioning work. General by the host GPS receiver hardware, antennas and power components. 3GPS application engineering test facilities in the application of GPS survey control net. Control network must be net-shaped structure of science, and little control of the actual burial place, the preparation of test facilities plan for the rational organization of personnel, equipment and vehicles (in particular, rational organization of dealers line can not be ignored). Here are four other companies in Shandong Aluminum GPS Control Network Network (Figure 1): 26 Shandong Architecture 2003 (1) circle a control network measurement projects,
Beats By Dre Studio, including work outside the industry, the choice of site, buried in stone and observations of three parts. The choice of site and buried stone shared five days. Laid a total of 53 new points, point number followed by G4001, G4002 ... ... G4053. Laid based on the following: In the soft ground according to 0.5 Figure laid. 4 frequently encountered problems and causes, the solution process of GPS measurements. In order to observe the accuracy of the results to meet the engineering requirements, often need to solve the first problem is whether a strict control point in accordance with specifications laid. Mainly in the following areas: control point near 4.1 high buildings or trees blocking the satellite signal receiving antenna, resulting in temporary suspension of the count the whole week. 4.2 from the ground control points too close to high voltage power transmitter, shown in Figure 2 in the 4027 numbers from the original point of the city is only 20 meters cable TV tower, and found the results of calculations associated with poor synchronization of ring closure of more than 1Oppm. 4.3 point under control point lay buried high voltage cable. Such as Zhongshan Road,
Salvatore Ferragamo outlet, Dalian buried high voltage cable. In this section of the GPS observations. After calculation. Found that cycle slip problem is very serious, almost unable to carry out baseline solution. Even if we manage to carry out the calculation. The result has too overrun. Can not meet the engineering requirements 4.4 control points near the surface there is a large area, resulting in the baseline calculations by the multi-path effects. Thereby reducing the quality of the observation. To solve such problems no other way. Only re-select the appropriate location. Re-laid. Re-observation. Second. Should be reasonable control network net-shaped structure, to both meet the regulatory requirements. Meet the engineering needs,
vibram five fingers outlet, but also efficient,
herve leger skirts, cost-effective completion of our work. Short. GPS technology is indeed painted the voltage received considerable technical progress. However, the layout of the construction application of the control network is still relatively small, do this in this area a useful exploration to obtain satisfactory results,
Beats By Dre Headphones, I believe that as technology advances in GPS positioning technology in the construction will play a greater role in measuring .
