Force Multiplier

约翰·休列里奇（John Hugerich）仍然记得使用基站，并为每个库存计算和洪水高程建立本地网络。这个过程繁琐且耗时，而总部位于美国新泽西州的Hugerich Construction的项目经理通常希望以更快，更轻松的方式完成工作。

那是两年前。今天，休列里奇几乎完全依靠HxGN SmartNet需要RTK校正的任务网络。

他说：“它使您可以在那里获得校正数据和所有国家飞机协调，因此它使生活变得更加轻松。”“仅仅能够耗尽工作岗位并获得快速库存数量或仔细检查现有的估计值，这对竞标工作和按时并按预算完成工作是非常有帮助的。”

Hugerich并不孤单。随着承包商寻求提高效率和生产力的方法，越来越多的公司正在用网络订阅代替一些基站，并从这种方法中获得好处。

提高可访问性，可靠性和效率

长期以来，测量师已经使用GNSS网络来节省时间和金钱，并消除了潜在的错误来源。网络用户没有携带GPS或GNSS，而不是在两个GPS接收器（一个基础和一个倒车）上拖着两个电池和电缆，两个无线电，一个三脚架和一个杆子，而是为每个项目设置自己的本地基础，而是为每个项目设置自己的本地基地带有调制解调器或手机的接收器（漫游者），并使用该设备快速访问永久参考站网络。来自这些永久电台的组合数据用于生成RTK校正，并在远距离远远远远不超出可能的距离上提供准确的定位。

使用网络节省了时间，因为它阻止了单独的基站的设置，并且避免了由于损坏或被盗而导致控制失败的风险。它还由于项目在项目过程中被撞到或撞倒时，由于基本站的设置不正确或替换而导致的潜在错误。对于承包商来说，它提供了能够从事他们准备出价的工作的能力，也许是在其他地方使用的基地，并迅速检查高程和数量以保护利润率。

在过去,获得一个可靠的、准确的network on a construction site was not a given. Contractors using GPS were almost always forced to set up their own local base stations to ensure accuracy. Over the last few years, however, substantial technology investments by the networks over the last several years, along with an increase in service capabilities, have made networks an attractive alternative for contractors seeking to take their productivity to the next level.

例如，北美的HXGN SmartNet被许多承包商和测量师视为最可靠的RTK校正网络，仅在过去两年中就添加了许多新的支持工具和数百个新的参考站。现在，它拥有1300多个站点，可为44个州和八个加拿大省提供GNSS校正数据覆盖范围，GPS和GLONASS覆盖范围，并且它继续迅速扩大。

增加的可用性与使用网络的好处相结合，正在推动建筑承包商以创纪录的数字注册订阅。HXGN SmartNet在2016年下半年看到了承包商的订阅，而2017年已经有望超越这些数字。

For most contractors, it’s the simplicity and speed of the network that is the most appealing. “I can hand a receiver to one of my operators and give him a quick tutorial on what he needs to do, and then go back to the office,” says Hugerich. “Once he’s onsite and gives me his coordinates, I can double check remotely to make sure everyone is on the same coordinates and that everything is running the way it should be. Ease of use is a really big thing.”

美国缅因州的蔡斯（Chase）发掘的米卡·索耶（Micah Sawyer）同意，指出使用HXGN SmartNet简化了他的公司的布局。他说：“这是快速而轻松的，这使我们在工作方面更有生产力。”

伙伴关系方法有助于确保成功

Advances in how networks serve the construction market are also contributing to the rise in network subscriptions. For example, base stations are still required for most machine control finishing operations to ensure vertical accuracy. HxGN SmartNet, however, recently rolled out a convenient site licensing option that allows contractors to purchase a single license for multiple rovers and machines on a project. With each site license, the service works closely with the contractor to densify the network so that the accuracies needed by machine control are achieved. The savings from not having to purchase a base station and repeaters provides a significant advantage. The larger the project, the greater the gains in efficiency.

Overall, the benefits of network subscriptions combined with the quality of service are leading to increased confidence and widespread adoption by contractors. “The increased efficiency of using a network really makes this the next logical step in construction,” Sawyer says.
