【正文】 M 系統(tǒng)的短信技術(shù)來實現(xiàn)箭載可回收產(chǎn)品的搜尋定位。當然在利益的驅(qū)使之下，許多的新業(yè)務(wù)及功能都是為了滿足用戶的移動定位需求，面對國內(nèi)人數(shù)超過 5 億的用戶群體，移動定位技術(shù)的快速發(fā)展也就顯 得迫在眉睫了。 自從美國國防部 1973 年提出 GPS 全球定位系統(tǒng) (Global Positioning System)，經(jīng)過二十余年的分階段建設(shè)，終于在 1993 年初具運行能力，現(xiàn)在已經(jīng)全面運行。箭載的各種存儲器都是需要返回陸地的，其內(nèi)部數(shù)據(jù)是我們認識太空環(huán)境的有力證明。 關(guān)鍵詞 ： GPS， GSM，定位，基站，短消息 The designe Of Position Searching Device based on GPS and GSM short message Abstract With increasingly close ties between the GSM work and GPS technology, the short message service of GSM system quickly became a new channels of establish munication link and data transmission in the application of the GPS positioning system. In order to solve the problem that the recyclable products is difficult to find,the Information Monitoring System Through GPS positioning and GSM base station location to get the exact latitude and longitude information and base station information, and then the information will be sent in the form of GSM short message . This paper describes the develop status and trends of domestic and international positioning first, and introduces the knowledge of GPS positioning and the knowledge of GSM, and then gives the ponents and the performance indicators of the monitoring system based on two methods of GPS positioning and GSM base stations positioning. In this paper, there ie a detailed description of parts of the module of the hardware, Including the power module circuit, GPS module circuit, GSM module circuit and microcontroller control module. One of the GPS module for receiving GPS latitude and longitude information, GSM module to send short messages via AT mands and queries GSM base station location information, the control of two modules to achieve through the microcontroller serial munication. In addition, by the watchdog program, serial munication program, GPS data extraction procedures and the GSM short message sending procedures for the preparation of the positioning device to plete the overall design process, and then details the key part of the positioning device debugging, includingthe AT mand port Communications testing, antenna testing, missioning. Protection against the problem of monitoring system, the paper first choice and design from the chip up to consider, then describes the process of protection issues that need attention.
