主题：【原创+文摘】免费的Google Maps Naviga -- 正宗鲁皮皮
首先看一看谷歌最近新推出的Maps Navigation的简介：
其对业界的影响马上显现：
Google Maps Navigation仅仅是Android 2.0系统里的一个应用，但它将Google的诸多技术整合在一起，包括Google Maps，Google Street View、语音识别、交通流量、卫星视图和强大的搜索，想想你只需要对着手机喊一句“离三里屯最近的必胜客”，手机就会一步一步的告诉你该怎么走，并在地 图、卫星图甚至是街景图上显示出路线图，是一种怎样神奇的体验？
Google Maps Navigation当然不会只限于Android系统，但Google Maps Navigation for iPhone能不能有还要取决于Apple的态度了。TechCrunch建议Google能屈尊在下雪天脱光光含泪361度转体俯卧撑跪求Apple能允许Google Maps Navigation进入App Store免费下载，我认为这个建议很靠谱！
通过CyanogenMod事件， 我们可以看出Google自有知识产权的Android应用并不能说是完全免费的，手机厂商需要为此付费给Google，当然如果山寨厂商通过非法手段将 未授权的Google应用也集成到Android系统里，那就是另外一回事了。Android系统确实免费，但不包括其中Google自有知识产权的应用 程序，这当然也包括Google Maps Navigation for Android 2.0。
还有命更苦的， 大家可以看一看这家公司，http://www.telenav.com/。Telenav对于一些河友也许还比较陌生，但在北美的同仁有些应该已经知道这家公司了，在智能手机上跑的一个导航服务就叫Telenav，其简介如下：
Find whatever you need wherever you are. Locate, call or navigate to rated and reviewed restaurants, hotels, ATMs, Wi-Fi hotspots and more from a directory of over 10 million businesses. No more expensive 411 calls.
Avoid traffic jams with real-time traffic alerts and intelligent rerouting.
Pre-plan trips online at My TeleNav. And by downloading an Internet browser plugin you can easily save addresses from any Web page to your phone.
Get automated updates of full-color 3D maps and business listings.
说它命苦是因为Telenav刚在11月2号申请IPO:
November 2, 2009 — 10:21am ET | By Jason Ankeny
Location-based solutions provider TeleNav filed plans with U.S. regulators to raise as much as $75 million in a proposed initial public offering. No estimated timetable for the IPO (managed by JP Morgan and Deutsche Bank Securities) was disclosed. According to the filing, TeleNav's voice-guided navigation service boasted more than 11 million paid subscribers worldwide at the end of Q3 2009--operator partners in the U.S. include AT&T and Sprint.
The timing of the TeleNav IPO is somewhat surprising given that the filing follows just days after web services giant Google announced the pending launch of Google Maps Navigation, a free turn-by-turn navigation app debuting on its Android mobile operating system. "Obviously, we like the price of free and consumers like that as well," Google CEO Eric Schmidt said during a preview of the service, adding the company can figure out how to make money from the product later. Many pundits are now questioning the continued viability of premium navigation apps like TeleNav, or at least casting grave doubts about their current monthly subscription-based models.

对于谷歌的免费服务，Telenav如何应对呢？
Probably both. TeleNav’s public S-1 filing with the SEC today has a lengthy Risks section that includes this clause:
“Google recently announced that it would offer free voice guided, turn by turn navigation as part of its release of Google Maps Navigation for mobile devices based on the Android 2.0 operating system platform. Competition from these free offerings may reduce our revenue and harm our business.”
The company’s currently in a quiet period after its IPO filing, so they’re not able to comment. But here’s the question I’d like to ask the founders and funders: Had you known Google would launch today, would you still have started TeleNav?
文摘完了，该谈谈鲁皮的几点看法：
1. 谷歌地图导航（Google Maps Navigation）对卫星导航芯片的生产厂家影响不大。除非它能不用卫星导航芯片。而众所周知，基于TOA的成本低廉的定位方案早已有时，但卫星导航芯片依然有自己的优势。
2.很难说PND市场就一定会被谷歌一统天下，因为我们必须考虑到在北美市场这项“免费”的导航应用必须基于手机的数据服务，而这项服务价格不菲。在美国买一个自主的PND也就是150美元左右，所以综合成本优势并不明显。毋庸置疑，Garmin等厂家的市场会被蚕食。最大的输家将是Telenav公司，估计又有一些硅谷的工程师们寝食难安了:)
3.基于手机的LBS应用才是以后的王道，现在谷歌的这些trick只不过是开始。不过，谷歌的举动会对整个基于手机的卫星导航芯片产业是个促进。
4.坊间已经有人放出话来，说谷歌此举有垄断行业之嫌，具体如何发展，静观其变。
搬个小凳看戏。
原名为“免费的Google Maps Navigation及其影响”
就是数据流量要收费，好像一月１０刀－－对于everything included得用户好像免费。
It says on the site that Sprint's navigation app uses Telenav as a back-end
确实，如果可以选，我肯定装ｇｏｏｇｌｅ的。

两相对比，TeleNav真是无奈的很。
不过放开心，30年河东，30年河西。当年APPLE还跟MS借过钱，现在的MS，不提了。
首先啊，这玩意要流量，这么算起来可是一点都不免费，大家用GPS的时候都是在路上，可没有免费的WIFI。
其次像交通流量啊这些数据获取，国家可以和美国学可以找一个“国家安全”的理由禁用掉。
精确度比Garmin或者TomTom这样专业做导航的差距很大,靠Google的地址数据导航有绕死的危险...
不过只要航拍/卫星图和街景能用,那就连地址都不需要了.不过这样对无线通讯带宽要求比较高...
拭目以待吧.
我对里面的思路与算法很感兴趣，能多讲些Map Service方面的东西吗，我想试试手机方面的地图应用。
国家这东西，也是一堆人组成的。
有搞定的可能，也有搞不定的可能。
他们好像已经和地图公司终止合同了，
现在要用他们自己的数据。
反正我们这里新建的楼盘GOOGLE MAP上都找不到，我相信GOOGLE
NAVIGATOR也找不到。
