If the operational misplay or dealing unsuitable with several technical problems in job, it would bring the strictness affection to the achievement because of RTK survey lacking of essential check condition yet.
Because of lacking necessary examining condition in RTK measurement,some error operation or improper technological treatment would bring badly serious influence on measurement achievement the article analysis the point around lake and high house or high energize line,using the known method to contrast coordination result from electronic total station and GPS-RTK survey,contrasting sincere precision with showing precision of GPS-RTK,then it discussed precision and reliability of GPS-RTK.
Furthermore observation quantity is less, and there are fairly perfect observation procedures and checking conditions (such as definite geometric conditions), so outliers are easily detected or cleared up. It can reach up to be ignored comparing remainder system errors with occasional errors.
Analysis to the new additional check factors is gi-ven, estimation formulation for the weakest point of the traverse is reached, and theoretical basis of the establishment of this kind of traverse is provided.
The result shows that this method can test all the checkout conditions including side and coordinate conditions, raise the capability of outlier detecting and locating in an adjustment system, and make the searching of closed loops in a surveying network realized satisfactorily with computers.
RTK is widely used in the fields of surveying for its advantages of being actual and high-efficient,but it lacks essential checking terms. If any fault or some technological problem appear,will bring serious influence on measurement.
In Experiment 2, the memory of subjects in the weapon condition was poorer than the memory of subjects in the check condition: In Experiment 1 similar, though only marginally significant, performance effects were obtained.
A necessary and sufficient condition for Higmanian in terms of certain partition of their vertex sets is given, followed by a necessary easy-to-check condition in terms of their parameters.
After the VA, the decoded sequence satisfies the parity check condition, thus the decoding procedure is terminated.
Check condition of piston cap and correct if necessary, lubricate inside of bell.
Personnel on different work shifts fail to check condition of hardware unless required by check or written directive.
In office calculation of closed traverse, the angle of connection is not corrected, because there is no check condition. The error of its measureing valueis impossible to avoid, the paper has made a detail analysis and offered a new method having a certain practical value in order to prevent mistake of the angle and to increase reliabilty of the result.
A method of the establishment and operation of aclosed non-orientatonal EDM traverse is discussed in this Paper. Analysis to the new additional check factors is gi-ven, estimation formulation for the weakest point of the traverse is reached, and theoretical basis of the establishment of this kind of traverse is provided.
An improyed plan for the 4th triangulation network in Dinghal region is introduced here. After the modification, the strength of the new network is obviously increased, the accumulated error effectively controlled, the checking condition added and the point accuracy raised.
