Field digitized drawing board application of modern microelectronics and sensor technology to quickly and accurately using topographic maps . It utilizes touch sensing technology to accurately measure the absolute or relative coordinates of any point in the drawings , and reuse of software programming techniques , fast solutions to calculate the distance and bearing between any two points , and can result to the command system , very greatly simplifies operating procedures using topographic maps , and improve the speed and accuracy of topographic maps , digital operation , digital communication and transmission of information . Compared with ordinary drawing board , field digitized drawing board operation is simple , full-featured , economical and durable . Take advantage of it to the job , not only can quickly obtain high - precision map coordinates , and on this basis , implementation artillery reconnaissance and security, the protection of geodetic firing computing field operations under conditions of informatization , improve the effectiveness of artillery combat laid a solid foundation. This article direct jobs in the amount of geodetic coordinates take the model to change the practices of geodetic coordinates topographic maps on the approximate amount taken to improve the accuracy of the geodetic coordinates measure ; perfect pass , as the case judgment model can provide users with more multi- parameter field judge . According to the model of the reconnaissance operations , design , program flow , and the completion of the program writing and debugging . Comparison test was part of the job of reconnaissance operations . Direct jobs in the reconnaissance section from the intersection job , double concept rendezvous jobs and Moroto computing jobs are traditional jobs comparison test , and the test results of performance analysis . Establishment of a database , to achieve the convenience of the operation of the various types of data . The unit of observation , artillery position coordinates , elevation , and target coordinates , attributes and other data storage and call ; valuable target coordinates for other Callray unit transmission , properties, and other data , the sharing of information resources . Application of the digitizing tablet were studied. Combined with the method of operation of each job in the digital drawing board , and the end of this article want , study the comprehensive application of the digital drawing board , hastily under the conditions in the digital drawing board simple method to determine shooting began firing .
