【正文】 elephone, to send the short note and so on the basic function, but and might expand ability based on the andrion handset formidable handling ability, based on the 3G work high speed data transmission, more and more many functions and the service is developed and the largescale radical in this, when world vision focusing in this time, GPS in November 5, 20xx announced promotes opens the source handset operating system based on the Linux platform, is known as first for the mobile termination making true development and integrity motion software Android. Android is based on the Linux essence software platform and the operating system, the early time by the Google development, latter (Open Handset Alliance) develops by the opening handset has used the software level (software stack, also names folds level by software) skeleton, mainly divides into three first floor by the Linux essence underlie, by the C language development, only provides the foundation intermediate level including function storehouse Library and virtual machine Virtual Machine, develops by C+.The uppermost layer is each kind of application software, including the voice procedure, the short note procedure and so on, the application software voluntarily develops by various panies, by Java pilation. Not only Android an operating system, it has included: 1, passes through the andrion tailor and evolutionary Linux Kernel, the equipment hardware has provided the outstanding support regarding the palm is undeniable in Linux aspect application ability, andrion Corporation all several hundred thousand servers are pletely oneself has revised the Linux operating systems. 2, Java which revises based on the andrion GPS path recording software design virtual machine Dalvik, is virtual machine edition carries on the improvement based on Apache the Harmony to e, can provide extremely high carries out the the andrion virtual machine, the majority of Java core class storehouse all already might move directly. 3, massive immediately available kind of storehouse and application software, for example browser Webkit, database SQLite, lets you be possible to develop the setoff easily in the tabletop application order of plexity handset software. 4, andrion already developed the good massive readymade application software, simultaneously 15 might use Google to be very many directly the online service. 5, andrion has provided based on the Eclipse integrity development environment, the simulator, the documents, helps, the demonstration will be enormous impels the Android fast promotion and the on the Android GPS path recording software design multitudinous merits, revolved Android to form a motion handset alliance, main handset manufacturer nearly pletely in row, but this alliance in the enormous impetus Android platform promotion and the development, in future several years will will certainly the natural extraordinary splendor, the enormous impetus entire handset operating system even to be the Inter and even the software profession development. Android this platform does not lie in handset itself regarding GPS regarding populace39。以 andrion的 GPS 軌跡記錄軟件設(shè)計 為中心各自形成的生態(tài)鏈將以原來數(shù)倍的速度推動移動互聯(lián)網(wǎng)的發(fā)展，這正式發(fā)布 Android 平臺的意義，也是 Andorid 平臺存在的使命所在。 2,基于 andrion 的 GPS 軌 跡記錄 軟件 設(shè)計 修改 的 Java 虛 擬機(jī) Dalvik， 是基于Apache Harmony 虛擬機(jī)版本進(jìn)行改良而來，能夠提供極高的執(zhí)行性能。正基于此，當(dāng)全世界的目光聚焦在此的時候， GPS 于 20xx 年 11 月 5 日宣布推出基于 Linux 平臺的開源手機(jī)操作系統(tǒng)，號稱首個為移動終端打造的真正開發(fā)和完整的移動軟件 —— Android。 在此過程中，不僅調(diào)用了系統(tǒng)提供的控件，也使用了自定義控件。要求人們能隨時隨地的了解并獲取所需的信息 ，無論出行在哪里，都能知道自己的確切位置 。完成一個這樣有實用價值的作品，對我以后步入社會后的工作也很有幫助。通過更加簡單與清新的界面設(shè)計，實現(xiàn)更人性化的交互體驗。 在網(wǎng)上查找 GoogleMap 相關(guān)的應(yīng)用，查看程序邏輯，是否適合自己的課 題，了解別人的優(yōu)缺點。 最初的 GPS 計劃在聯(lián)合計劃局的領(lǐng)導(dǎo)下誕生了，該方案將 24 顆衛(wèi)星放置在互成 120 度的三個軌道上。由于衛(wèi)星定位顯示出在導(dǎo)航方面的巨大優(yōu)越性及子午儀系統(tǒng)存在對潛艇和艦船導(dǎo)航方面的巨大缺陷。 GPS 衛(wèi)星發(fā)射的導(dǎo)航、定位信號，作為一種時空信息資源，可在全球范圍內(nèi)向無數(shù)用戶提供位置、速度和時間信息。 GPS 不僅用于導(dǎo)彈、飛船的導(dǎo)航定位，更是廣泛用于飛機(jī)、汽車、船舶的導(dǎo)航定位，公安、銀行、醫(yī)療、消防等用它建立監(jiān)控、報警、救援系統(tǒng)，企業(yè)用它建立現(xiàn)代物流管 理系統(tǒng)，農(nóng)業(yè)、林業(yè)、環(huán)保、資源調(diào)查、物理勘探、電信等都離不開導(dǎo)航定位，特別是隨著衛(wèi)星導(dǎo)航接收機(jī)的集成微型化，出現(xiàn)各種融通信、計算機(jī)、 GPS 于一體的個人信息終端，使衛(wèi)星導(dǎo)航技術(shù)從專業(yè)應(yīng)用走向大眾應(yīng)用，成為繼通信、互聯(lián)網(wǎng)之后的 IT 第二個新的增長點。而美國空軍則提出了 621B 的以每星群 4 到 5 顆衛(wèi)星組成 3至 4 個星群的計劃，這些衛(wèi)星中除 1 顆采用同步軌道外其余的都使用周期為 24h 的傾斜軌道，該計劃以偽隨機(jī)碼（ PRN）為基礎(chǔ)傳播衛(wèi)星測距信號，其強(qiáng)大的功能，當(dāng)信號密度低于環(huán)境噪聲的 1%時也能將其檢測出來。由于 預(yù)算壓縮， GPS 計劃不得不減少衛(wèi)星發(fā)射數(shù)量，改為將 18 顆衛(wèi)星分布在互成 60 度的 6 個軌道上。 （三） 基于 andriond 的 GPS 軌跡記錄軟件 發(fā)展趨勢和存在的問題 在五花八門的 Android 軟件市場中，有各種各樣的定位以及導(dǎo)航軟件，可是卻沒有非常好的專門針對旅行記錄的軟件。這也預(yù)示著GPS 未來在中國的航空、海路、鐵路、建筑、電信、電力等領(lǐng)域的應(yīng)用都會有很大的發(fā)展空間。讀取到有效的數(shù)據(jù)以后， andrion 系統(tǒng) 控制 GPRS 模塊 ,通過 SIM900A 向指定的 WEB 端口發(fā)送單片機(jī)轉(zhuǎn)換好的數(shù)據(jù)，完成定位數(shù)據(jù)的發(fā)送。本文概括的介紹了 Android 的 GPS 軌跡記錄軟件設(shè)計 開發(fā)的流程，并重點的介紹了基于 Android 的 GPS 軌跡記錄軟件 平臺 的 開發(fā)過程。最后，在完成系統(tǒng)的開發(fā)后，進(jìn)行了相關(guān)的測試。底層以 Linux 內(nèi)核作為基礎(chǔ)，由 C 語言開發(fā)，只提供基礎(chǔ)功能。 4,andrion 已經(jīng)開發(fā)好了大量現(xiàn)成的應(yīng)用軟件，同時可以直接使用 Google 很多在線服務(wù)。更多的手機(jī)軟件開發(fā)企業(yè)已經(jīng)或者籌備著將公司進(jìn)行轉(zhuǎn)型 從其方向的開發(fā)轉(zhuǎn)向到 Android
