The Development Of Control Sotfware In SLR System

Laser ranging technique is comprehensive, which concerns in differentresearching fields, such as laser, electronic, glimmer director, automaticcontrol, precision optical machinery, astronomical survey, orbit calculationof satellites and so on. SLR is one of the most important means in space geodetic,it is a key application in precise orbit determination, precision time comparison,accurate determination of earth rotation parameters and terrestrial referencesystem. The development of technology continuously promotes the laser rangingtechnique. Because laser ranging has advantages of high precision, wellstability, a large number of data, the application of laser ranging techniqueis more and more extensive.In this article is to ChangChun Satellite Observatory Station’s distancemeasurement as the background. In the light of observation system of controlsoftware for basic needs and the realization of a detailed introduction. First,introduced the principle of laser ranging, development, present situation andsystem composition. Then the requirement analysis of this software and the mainalgorithm. At the same time the paper also introduced the laser ranging controlsoftware modular and software design. As well as software realization processpart of the code.The satellite laser ranging distance measurement control software is aspecial one for user operation. It can assist surface observation stations tocontrol the hardware equipments of SLR system, and make them coordinate workquickly, effectively and stably. This ensure that each hardware work real-timeand stabilization in high repetition frequency KHz SLR. The software runsindependently, which is divided into time, data process, instrument setting andhelp files for four sections. The satellite laser ranging distance measurementcontrol software is running under the WindowsXP operating system. To completed KHz satellite laser ranging control. It has a beautiful user interface. Autocompletion of the data collection and control, Automatic identification ofeffective data, Automatic data storage file, It also can under a multiple usersystems in a high speed at a real time control and data collection. For laserranging staff engaged in scientific research staff to provide convenientconditions and good foundation.
