厂商解读:凯立德

[Source: 易观 ]

凯立德成立于1997年,最初以开发大型国土资源管理系统为主要业务,随后也推出地理信息系统行业应用服务,并在这些项目服务中开始地图数据的采集业务,1999年开始开发导航引擎软件。在便携式导航领域,凯立德向硬件厂商提供地图数据、引擎一体化方案,目前为e路航、奥可视、神行者等PND品牌提供导航软件。易观分析认为,凯立德在PND导航领域的主要优势有:

1、地域优势。国内大部分PND生产企业位于广东省,作为唯一一家总部位于深圳的导航地图企业,凯立德在与PND硬件厂商的合作中具有地域优势,这一优势为凯立德赢得了大量的PND中小品牌客户。
2、软件易用性。凯立德导航软件的地图数据与引擎底层联系紧密,这一方面是导致凯立德只能提供数据、引擎一体化方案的原因,一方面也使得软件的速度较快。同时凯立德软件的UI设计也比较便于新手使用。
3、用户认知度。除了向硬件厂商提供软件使用许可以外,凯立德导航软件也有面向终端用户的零售模式,这是用户对该软件品牌比较了解的原因之一。另外,与电视直销品牌的合作,也提高了最终用户对凯立德品牌的了解。

上述这些优势使得凯立德导航软件具有较大的用户存量,但是以下几个问题也困扰凯立德的发展:

1、定位相对低端。由于大部分合作伙伴均为中小品牌,凯立德的品牌定位显得相对低端,特别是Mio与凯立德合作终止以后,凯立德比较缺乏大品牌客户。近期竞争对手对知识产权纠纷的过度宣传,也使得凯立德在品牌形象建设方面显得有些被动。

2、盗版产品泛滥。市面上有大量PND产品安装盗版凯立德导航软件,这使得凯立德导航软件尽管拥有数量巨大的用户,但并不能为其带来实质收入。

Archos 605 GPS

Finalement, le 605 GPS nous laisse un goût de logiciel inachevé. Des lenteurs occasionnelles, des itinéraires qui passent par des voies piétonnes, un récepteur TMC qui ne capte pas d’info-trafic, des choix étranges dans les menus, sont autant de défauts que l’on retrouvait sur les premières générations de GPS. Les concurrents ont aujourd’hui corrigé la plupart de ces erreurs de jeunesse, et il faudra au 605 GPS passer par là pour venir concurrencer les PND  »purs et durs » sur leur terrain de prédilection. Après une amélioration du logiciel, le 605 GPS pourrait devenir un GPS très intéressant quand on connaît les prouesses dont il fait preuve en usage multimédia.

Il n’est pas pour autant mauvais et saura vous mener sans encombre d’un point A à un point B. Il se destine à ceux qui cherchent un bon lecteur multimédia qui sert occasionnellement de GPS, mais pas à ceux qui cherchent un bon GPS qui fait aussi office de lecteur multimédia. (>>more)

MTK动作缓 MStar/威航领跑GPS价格战

[source: 国际电子商情]

联发科技(MTK)去年正式进入GPS市场,让众多粉丝无比兴奋。这些粉丝希望MTK能像在手机芯片市场的成功一样,带领其众多客户在GPS市场快速赚到钱。 然而,时间几乎过去一年,其众多粉丝开始失望。因为,到目前为此,MTK的GPS方案在价格上没有任何竞争力,反而是另外两家台湾厂商MStar和SkyTraq(威航科技)走得更前一些。 Read the rest of this entry »

Perspectives by Eric Gakstatter

This may be the most important column I’ve ever written. It’s certainly the most expensive. At $40,000 worth of equipment for this writer, multiplied by 17,346 readers, we’re talking $694 million. And that’s not nearly the full extent of industry impact; the Department of Commerce has some figures that I will quote later.

Is Dual-Frequency GPS — As We Know It — Becoming Obsolete?
On Friday, May 16, 2008, the Office of Space Commercialization issued a Notice for Public Comment. In it, the U.S. Department of Defense (DoD) proposes to discontinue supporting P(Y) codeless/semi-codeless on both GPS L1 and L2 frequencies on modernized satellites (Block IIR-M, Block IIF and Block IIIA/B/C) beginning December 31, 2020. After 2020, legacy dual frequency receivers may still work, but the DoD would no longer assure that P(Y) power levels and the navigation message would remain the same. Therefore, the civil GPS community has no assurance that legacy dual frequency receivers will operate as before.

Essentially, this means that every dual frequency receiver designed in the 1980′s, 1990′s and many in the early 2000′s would become virtually obsolete. In the interest of disclosure, that includes my own legacy real-time kinematic (RTK) system.

I caution you … it is very easy to rush to judgment regarding this proposal. When I first read it, my first response was « Whoa, dude, no way! » However, it’s important to take a deep breath and work your way through the logic. Your conclusion may be the same as your initial response, but at least you’ve thought it through. That being said, you must also realize that this is the first action, in the history of GPS, which will render a massive amount of GPS equipment obsolete. read more>>
