Satellite and terrestrial geodetic network adjustment method of uniform


Q2 a 022Q. Q22) I =. <Q.һ 0: DQDoi). The method described is easy with the existing root Nice Pula Pula Nie Weiqi a large-scale geodetic network of the adjustment method statement sets up, then, in turn name the common point, and the methods used to gradually eliminate the unknown solution algorithm equation. Localized in the rough equation solving system (9), with the process of solving inverse point coordinates only broad access to public corrections (1O) and their associated matrix (11). Meanwhile, the final operation is calculated and the value (16), while and for the gain error of unit weight is required. Finally solving their common point when the free (17) corrected repeat the process of being counted, but inverse process is completed. The same way during the inverse correlation matrix in the calculation of 0, (13) when the coefficient equation solver Cong Department (6). . In other ways the ground geodetic network adjustment, the time part of the independent parameters can not be eliminated (for example, the conjugate gradient method), the approximate partial equation system solver solver and can eventually be completed. At this time point should be given to public note, this is to solving the rough, there are options to calculate the correlation matrix 0. Elements and the final solution in the calculation of free term t for correction. Using this method, solver consists of three parts of the general formula (5) Pat meaningless. And the local geodetic network weight matrix as the basis for the sum of simultaneous equation solver of Known compared the proposed method for obtaining an infinite number of elements in the terrestrial network in the starting point of the weight matrix does not require special procedures, as the method is based on correlation matrix (7) based on the sum. In addition, contact solving equation (3) of the process, from the independent local geodetic network solver to obtain the covariance matrix may be more precise, this is another advantage of this Law. To correct for this by the number of the second the diagonal covariance matrix for the values in the. 2i =(��)�� 022,2 = (.) 02. covariance matrix of the correction with the number of a Man t () (: F) | 1 (2o) 0 :=(��) a (J + stare E) Calculation of matrix G (7) the new value and repeat the equation solving contact. This process continues until the conversion element values to achieve tolerance requirement. local law of the corrected equations Free entry in the final solution is different from the calculation formula (17), which has the following form ... 2 = 2 +0 iiul ,:=+( 0) a 'Z2 (21) because in equation (2) the parameters of surface geodetic network is a plane rectangular coordinates, Y, then D is not a square matrix, the matrix D is no inverse matrix. For terrestrial network and satellite ground network common point, the matrix dead: only the right to increase the height of the corpse:. This allows each plane coordinate variance calculation., and high variance of Er. in the results can be made up in various ways to establish the correlation matrix of geodetic network is more accurate, with least square method is not always reflected in the formal evaluation of the actual precision geodetic network. the former Soviet possession, , t testis, Guo Mountain, t testis, Guo Mountain, the trial t take, Guo Mountain, in the trial in the t take, take in the t, in (on the next page 39) use an internal table data can reduce the amount of data storage can be quickly re- classification. image processing technology is the system data analysis and data conversion in the important part. map to display vector and grid structure. the color output can be displayed on the screen (up to 255 colors.) Tektronix color printers using and IBM inkjet plotter and pits, or other machine available in hard copy map. tabular data, statistics and reports by the relationship between the AO database provides current and cereals are a number of hydrological forecasting model evaluation studies, to seek development in a number of countries meet their data needs and adapt to the use of models. for specific applications and for some of the environmental and economic conditions, with different local application of the rule base is also being developed.] / E Ao in the search for the relationship database, maps analysis package, image processing technology to achieve highly integrated approach. This is one of the main items urgently. Although the main purpose of this system is to provide decentralized, low-cost information systems. but i also need to hold the line network operation Research and Development, to further the use of the mainframe or minicomputer Are / Info or Usemap that geographic information systems. reference to the text more (slightly) snapped capsule Netherlands Technology 3
