Blackberry 黑莓全球定位系统标准

我正在为BB开发一款具有GPS功能的应用程序。但问题是，GPS标准因运营商和设备而异。那么，有人知道可以使用哪些不同的标准吗？我试图使用不同的链接BB支持论坛，但我没有得到任何保证的方式，这应该适用于每一种情况。提前谢谢

谢谢,；

无编辑：抱歉，刚才注意到您的问题是关于承运人的标准。。。所以这不是确切的答案

我不是黑莓GPS标准方面的专家，我的答案是基于我使用过几次它

根据我的经验，GPS标准是基于一组要求精度、功耗和成本的，您可以将这些输入标准对象。例如，这里是我从网上得到的一些代码

 /**
     * assisted: Use this mode to get location information from satellites using a PDE. This mode allows a BlackBerry device
     * application to retrieve location information faster than the autonomous mode and more accurately than the cell site mode.
     * To use this mode requires wireless network coverage, and the BlackBerry device and the wireless service provider must
     * support this mode.
     */
    private Criteria getAssistedCriteria(int powerConsumption) {
        Criteria criteria = new Criteria();
        criteria.setHorizontalAccuracy(100);
        criteria.setVerticalAccuracy(100);
        criteria.setCostAllowed(true);
        criteria.setPreferredPowerConsumption(powerConsumption);
        return criteria;
    }


    /**
     * autonomous: Use this mode to get location information from the GPS receiver on the BlackBerry device without assistance
     * from the wireless network. This mode allows a BlackBerry device application to retrieve location information that has highaccuracy,
     * and does not require assistance from the wireless network. However, the speed at which this mode retrieves
     * location information is slower than the other modes.
     */
    private Criteria getAutonomousPosCriteria() {
        Criteria criteria = new Criteria();
        criteria.setCostAllowed(false);
        return criteria;
    }

    /**
     * cell site: Use this mode to get location information from cell site towers. This mode allows a BlackBerry device application
     * retrieve location information faster than the assisted and autonomous modes. However, the accuracy of the location
     * information is low-level and does not provide tracking information such as speed or route information. Using this mode
     * requires wireless network coverage and that both the BlackBerry device and the wireless service provider support this mode.
     */
    private Criteria getCellSiteCriteria() {
        Criteria criteria = new Criteria();
        criteria.setHorizontalAccuracy(Criteria.NO_REQUIREMENT);
        criteria.setVerticalAccuracy(Criteria.NO_REQUIREMENT);
        criteria.setCostAllowed(true);
        criteria.setPreferredPowerConsumption(Criteria.POWER_USAGE_LOW);
        return criteria;
    }

看看这个JavaDoc中的表：

我现在也在处理这个问题。。。如果您没有看到它们，这两个链接对我很有帮助：最近在Verizon论坛上的一些讨论-看起来它们只支持独立模式：
