PBO is aware of the issue and is working on the problem.
DATUM REALIZATION FOR THE OREGON REAL-TIME GNSS NETWORK
On Friday, 8 March 2013, the Oregon Real-time GNSS Network (ORGN) was transitioned to a new datum realization: NAD 83(2011) epoch 2010.00. Please visit our ORGN Coordinates page for more in depth information on this transition.
GLONASS and the Oregon GNSS Network
Please see our GLONASS web page for information about GLONASS and the Oregon Real-time GNSS Network.
The Oregon DOT Geometronics Unit is operating and expanding the Oregon Real-time GNSS Network, a network of permanently installed, continuously operating GNSS reference stations.
The ODOT Geometronics Unit is responsible for enhancing and maintaining the vertical and horizontal geodetic control infrastructure across the state of Oregon. The establishment and operation of the ORGN in Oregon helps us accomplish this mission.
This GNSS network consists of GNSS Continuously Operating Reference Stations (CORS) that provide real-time kinematic (RTK) correctors
to field GNSS users over the internet. GNSS users that are properly equipped to take advantage of these correctors can survey in the field to the one centimeter horizontal accuracy level in real-time. RINEX files
are also available for use in post-processing.
SCOPE OF NETWORK
Currently GNSS corrector coverage by the ORGN consists of several sub-networks, or clusters of stations in Oregon. Each sub-network consists of GNSS stations spaced at 70 km, more or less.
The Oregon Real-time GNSS Network is operated and controlled by ODOT using specialized GNSS network software (Leica GNSS Spider) running on servers at the Oregon Department of Transportation in Salem. The GNSS network software is used to configure and monitor the quality of data from the reference stations, compute GNSS correctors, and then provide GNSS correctors to field GNSS users. Correctors will be provided in real-time via internet connectivity. GNSS data from reference stations will also be archived and available on-line in RINEX file format for users that need to post-process their field GNSS data.
The ODOT Geometronics has partnered with other state and local government agencies, as well as educational institutions and private industry, to develop the ORGN. Our partners have contributed some of the facilities and GNSS equipment for the ORGN. In turn, ODOT Geometronics has purchased and is operating the GNSS network software that controls the network of CORS stations from central computers. The ODOT Geometronics Unit and ODOT regions have also provided many station sites and installed many GNSS sensors for the ORGN.
