從兵器工業集團獲悉，具備北斗三號短報文通信能力的大眾手機即將面市，將重新定義手機功能應用，有效支持人民生命安全財產保障。
北(bei)斗(dou)(dou)短報文功能，簡單地說就(jiu)是(shi)在無通(tong)信網絡的情況下，通(tong)過北(bei)斗(dou)(dou)衛(wei)星系統(tong)進(jin)行雙向信息發送、接收，是(shi)北(bei)斗(dou)(dou)衛(wei)星導航(hang)系統(tong)的獨家“絕(jue)活”。近年來，北(bei)斗(dou)(dou)系統(tong)對經濟(ji)社會發展(zhan)的輻射帶動作用顯著增強，應用深度廣度持續拓展(zhan)，已進(jin)入規(gui)模應用市場化(hua)、產(chan)業化(hua)、國際化(hua)發展(zhan)關鍵階段。 除了(le)(le)短報文功能(neng)(neng)，以(yi)北斗(dou)系統(tong)為(wei)基(ji)礎研發(fa)的手機導航也(ye)實(shi)(shi)現了(le)(le)道路級識別(bie)的精度，在(zai)車(che)輛(liang)(liang)行駛過(guo)程中(zhong)，導航系統(tong)不僅可以(yi)準(zhun)確(que)顯(xian)示目前(qian)車(che)輛(liang)(liang)所處的車(che)道位置(zhi)，甚(shen)至地(di)面的實(shi)(shi)線(xian)和虛(xu)線(xian)也(ye)能(neng)(neng)準(zhun)確(que)進行標識。 2021年5月(yue)，兵(bing)器工業集團(tuan)在北(bei)(bei)(bei)京舉辦北(bei)(bei)(bei)斗三(san)號短(duan)報(bao)文通(tong)信(xin)融入大眾手機階段成果展示(shi)會(hui)，現(xian)場演(yan)示(shi)普通(tong)智能手機直接與距地面(mian)約3.6萬公里高(gao)度的北(bei)(bei)(bei)斗衛星通(tong)信(xin)，成功完成短(duan)報(bao)文信(xin)息互通(tong)，標(biao)志著北(bei)(bei)(bei)斗短(duan)報(bao)文通(tong)信(xin)由(you)傳統專用(yong)(yong)終端應用(yong)(yong)，邁入面(mian)向(xiang)大眾手機直接提供(gong)(gong)服務(wu)的新(xin)階段，為(wei)北(bei)(bei)(bei)斗系(xi)統提供(gong)(gong)更優(you)質、更便捷、更佳用(yong)(yong)戶(hu)體驗的短(duan)報(bao)文通(tong)信(xin)特(te)色(se)服務(wu)奠定(ding)堅實技術基礎。 北(bei)斗(dou)三號(hao)(hao)(hao)短(duan)(duan)(duan)報(bao)(bao)(bao)文(wen)(wen)(wen)(wen)通(tong)(tong)信(xin)(xin)在北(bei)斗(dou)二號(hao)(hao)(hao)的(de)基礎上(shang)進行(xing)(xing)了(le)升級換代，提(ti)高(gao)了(le)系統(tong)服務(wu)容量(liang)，降低了(le)終端發射功率。經北(bei)斗(dou)三號(hao)(hao)(hao)系統(tong)建設(she)(she)(she)任務(wu)擇(ze)優(you)，由兵器工(gong)業(ye)集(ji)團(tuan)聯合中(zhong)國移動、中(zhong)國電(dian)科等(deng)單(dan)位，承擔建設(she)(she)(she)了(le)北(bei)斗(dou)三號(hao)(hao)(hao)短(duan)(duan)(duan)報(bao)(bao)(bao)文(wen)(wen)(wen)(wen)通(tong)(tong)信(xin)(xin)民用應(ying)用服務(wu)平臺。目的(de)是推(tui)進北(bei)斗(dou)短(duan)(duan)(duan)報(bao)(bao)(bao)文(wen)(wen)(wen)(wen)與移動通(tong)(tong)信(xin)(xin)融合，實現短(duan)(duan)(duan)報(bao)(bao)(bao)文(wen)(wen)(wen)(wen)由面(mian)向(xiang)行(xing)(xing)業(ye)服務(wu)向(xiang)面(mian)向(xiang)大眾服務(wu)的(de)拓展轉型(xing)。北(bei)斗(dou)短(duan)(duan)(duan)報(bao)(bao)(bao)文(wen)(wen)(wen)(wen)通(tong)(tong)信(xin)(xin)進入大眾手(shou)機，創(chuang)新移動通(tong)(tong)信(xin)(xin)編碼和(he)高(gao)靈敏度信(xin)(xin)號(hao)(hao)(hao)捕(bu)獲(huo)等(deng)多(duo)項(xiang)技(ji)術(shu)，攻(gong)克大眾手(shou)機體積(ji)約束強、功耗(hao)要求高(gao)等(deng)關鍵(jian)瓶頸，實現手(shou)機“不(bu)換SIM卡、不(bu)換手(shou)機號(hao)(hao)(hao)、不(bu)增加額外設(she)(she)(she)備”即可(ke)同時享受北(bei)斗(dou)短(duan)(duan)(duan)報(bao)(bao)(bao)文(wen)(wen)(wen)(wen)和(he)移動通(tong)(tong)信(xin)(xin)服務(wu)。
