Targeting Orbit Recording Device Based On GPS Design And Implementation

Targets are the targets that are often used in the development,design,design,missile sampling and troop combat training.It is an indispensable and important equipment for the assessment of the air defense weapon system.It is important for the improvement and upgrading of the air defense weapon system.Test assurance.Targeting in the movement characteristics such as flight height,speed,overload and so on can be more realistic description of the aircraft characteristics.The main features of the target system are: fast,good mobility;air defense weapons combat effectiveness directly depends on the level of development of target technology.In the process of the development of the target,there is always a "good" and "affordable" between the fundamental contradictions,on the one hand,with the rapid development of modern defense technology,air defense weapons need to combat the actual combat conditions in combat On the other hand,because the target is a non-combat equipment,and is a one-time use of consumables,target development and investment of human resources and limited resources,restricting the target The rapid development of bomb technology.Air force,army and other arms training,the need for a large number of target bombs,the existing target does not have the control function,can not draw accurate target trajectory,the evaluation of the training results have a certain impact,especially the training force did not find the target,It is easy to analyze the reasons,to improve the training results is very useful.The change of the attitude angle of the antenna is realized by two stepping motors,that is,the pitch angle change and the rotation change,which constitute the basic frame of the experimental platform.The high-dynamic GPS navigation and positioning technology is used to record the flight path of the target.The radio station real-time transmission of the target position information,the above three parts to complete the simulation of the target part of the ground;wireless data transmission station will receive the location signal to the computer system to rebuild the track.The above constitutes the entire experimental platform hardware equipment,can be a good simulation of the state of the target flight,for the subsequent data collection and data processing to lay a solid foundation.The software part is through the preparation of C language to achieve the stepper motor control;use matlab software to complete the data processing part,draw the target movement of the trajectory.This paper first introduces the composition and working principle of GPS navigation and positioning system,and uses the GPS receiver to obtain the position information of the target.The stepping motor is used to simulate the positioning of the GPS antenna to verify the GPS receiver The authenticity and reliability of the information,the experimental verification based on GPS and the Big Dipper and other navigation equipment can achieve the target track of the real-time recording and transmission,to be required to locate the search time,data refresh signal field strength and other parameters,from which we can Get some problems in the positioning process,pave the way for the follow-up research.
