Reference Stations

GNSS Reference Station Networks: The Missing Piece for Surveying & Construction

Why Leica GNNS Network RTK?

Leica Networks employ the unique networking software SpiderNET, that allows end users to benefit from the entire GPS network at once. Unlike traditional systems that employ simple baseline corrections from one Reference Station, SpiderNET gives the user a an atmospheric corrected signal. This is possible because SpiderNET computes the user’s position from within the total network.

Imagine all of the following capabilities with the hassle, expense and vulnerability of an on-site GNSS Base Station:

Construction & Building

Reference Station Networks provide increased production, efficiency and control to many phases of construction projects including:

  • Construction Stake Out and Lay Out
  • Site and Road Excavation and Grading
  • Machine Control of Graders, Dozers and Excavators
  • Easily Updated and Calculated Job Quantities and Material Volumes
  • Minimized Downtime waiting on Grade Stakes
  • Faster Job Completion with a Increased Accuracy

Homeland Security & Structural Monitoring

Reference Station GNSS infrastructure provides the ability to monitor critical structures. Leica Geosystems is the leader in structural monitoring solutions. Rapid notification of critical changes due to attack or disaster could potentially save thousands of lives and provide strategic information to better manage such an event.

Real Time streaming of data from a structure or site

Latest Monitoring and Analysis Technology

Suited for many structure types including Buildings, Bridges, Towers and Dams

GIS (Geographic Information Systems)

GIS Data Collection Initiatives are performed more accurately and efficiently with Reference Station GPS Infrastructure.

  • Most accurate Differential correction available. (much better than WAAS or CGB)
  • Data Integration within a Network allows for seamless GIS coordinate collection and data sharing
  • Easy Upgrade Path from GIS to Survey for high accuracy Data Collection such as elevation information.

Natural Disaster Recovery

During a Natural Disaster utilities can be disrupted and outages can prolong the suffering of residents of the affected area for days, weeks or even months. Often, critical utility structures such as valves, manholes and fire hydrants need to be located to protect or redirect the utility system.

GNSS Reference Station infrastructure provides Utility Officials and Technicians accurate data to pinpoint these vital structures. Often the location of these items can be severely or hidden altered by mud, snow or debris. Utilization of GPS in conjunction with RTK may be the quickest and sometime only way to find these locations.


Reference Station GPS provides increased production and efficiency to many phases of the surveying projects. All of the following capabilities without the hassle and expense of individual GPS Base Stations.

  • Perform centimeter level accuracy RTK surveys with one Rover
  • Double surveying capacity by converting existing Baser into a Rover
  • Eliminate human error in Base setups
  • Reduce dependency on Ground Control Monuments
  • Greatly extend RTK Range over standard UHF radio setups
  • Peace of mind that the Network is accessible and monitored 24/7 by SpiderNET
