What are Multiple Reference Frames Mountpoints?

Multiple Reference Frame (MRF) Mountpoints allow users to get to the Reference Frame and Epoch they need to conduct field operations in real-time. 

Multiple Reference Frames for High Dynamic Areas

For example, in California due to our semi-annual adjustment cadence, a customer may have the need to go from Current Class of coordinates - NAD83(NA2011) Epoch 2017.750 to the Last Class of coordinates - NAD83(NA2011) Epoch 2017.250 to finish a project.

Previously, this required the customer to perform a new transformation, localization or calibration on the site.  Now with MRF Mountpoints, the customer simply has to change their RTK profile to a new mountpoint and they will immediately receive a correction utilizing the 'old' NAD83(NA2011) Epoch 2017.250 coordinates.

Multiple Reference Frames for Legal Requirements

Additionally, in some areas there are legal requirements to tie to a specific Reference Frame and Epoch.  With MRF Mountpoints, we now have the ability to allow a customer to select the mountpoint that best fits to their needs.  For example, in British Columbia there are different requirements for Victoria Island and the BC Mainland. 

Previously, this required the customer to perform a new transformation, localization or calibration to adhere to the statutes.  Now with MRF Mountpoints, the customer simply has to change their RTK profile to a new mountpoint and they will immediately receive a correction utilizing the either NAD83(CSRS) Epoch 1997.00 or NAD83(CSRS) Epoch 2002.00.

Multiple Reference Frames for Legal Requirements

 To relate the Multiple Reference Frame to the coordinate class of the station you are using, you will need to refer to the SmartNet Site Database.  Here you will find the following coordinate classes referenced

In High Dynamic Areas

  • Current
  • Last
  • Common 

In Legal Requirement Areas

  • Current
  • Alternate

In Standard Areas

  • Current is equal to Common (they are the same)
