Force Multiplier

约翰Hugerich还记得使用基站and setting up a local network for every stockpile calculation and flood elevation. The process was tedious and time-consuming, and the project manager of Hugerich Construction, based in New Jersey, USA, often wished for a faster and easier way to get the job done.

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。

Using a network saves time since it precludes the setup of separate base stations, and it avoids the risk of having control fail due to a damaged or stolen base. It also eliminates potential errors due to the incorrect setup or replacement of the base station if it gets bumped or knocked down in the course of the project. For contractors, it provides the ability to go to a job they’re preparing to bid, perhaps while their base is in use elsewhere, and quickly check elevations and quantities to protect profit margins.

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。

The increased availability combined with the benefits of using a network is driving construction contractors to sign up for subscriptions in record numbers. HxGN SmartNet saw subscriptions by contractors double in the second half of 2016, and 2017 is already on track to eclipse those figures.

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.”

Micah Sawyer of Chase Excavating in Maine, USA agrees, noting that using HxGN SmartNet has streamlined layout for his company. “It’s fast and easy, and it makes us more productive on our jobs,” he says.

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.

HxGN SmartNet, based on Leica Geosystems GNSS technology, is the GNSS correction service built on the largest reference station network in the world that brings the highest precision results. HxGN SmartNet continues to provide trusted GNSS data over more than 4,000 reference stations worldwide. The new naming of HxGN SmartNet reflects the ability of combining Leica Geosystems technology with other Hexagon businesses. Login procedures will not change, and users will be able to continue their service seamlessly.
