Real-time correction products will be provided to users with valid Rover Accounts.
All rover users will be issued a Rover Account at no direct charge; however, ODOT reserves the right to charge a nominal Rover Account fee in the future to cover operations and maintenance of the ORGN only, not to cover development costs of the ORGN. In the event that ODOT must start charging for Rover Accounts, ORGN partners will continue to receive Rover Accounts at no charge.
A partner is defined as an individual, agency, or business that contributes substantially to the infrastructure of the Oregon Real-time GNSS Network. An individual, agency or business may qualify as a partner of the ORGN by providing a GNSS reference sensor and antenna and/or a site for a reference station for the ORGN.
In order to access the real-time correctors from ORGN, you will need a GNSS rover that is capable of receiving real-time correctors in RTCM 2.3 or RTCM 3.x format. Both formats are non-proprietary as it is the policy of the ORGN not to send out correctors in any manufacturer proprietary format; however, we do provide correctors in the Trimble CMR+ format.
Each Rover Account will be issued an NTRIP user name and password for authentication which allows the rover to log onto the ORGN server that streams real-time correctors. NTRIP is an acronym for "Networked Transport of RTCM via Internet Protocol" and is an application-level protocol for streaming Global Navigation Satellite System (GNSS) data over the Internet. NTRIP is a generic, stateless protocol based on the Hypertext Transfer Protocol.
You must also have a cellular modem or data-capable cell phone that is connected to your rover and you must purchase a data service plan from a cellular provider. Both CDMA (example: Verizon, Sprint) and GSM (examples: Cingular, Unicel) cellular formats are capable of accessing the ORGN server that streams RTK correctors. You should pick a cellular provider based on which provider provides the best data service coverage in the area where you will be working most.
The rover user will be responsible for purchasing, configuring, and maintaining the appropriate GNSS rover, cell modem, and cellular data service. ORGN_Support will provide general support, but cannot provide support for configuring and using specific GNSS equipment, specific cellular modems, or data service. Please contact your GNSS equipment manufacturer or vendor for GNSS support and your cellular provider for cellular service support. We will post support documents for specific equipment and FAQ's as they become available.
