Montana State Reference Network
Ready for Subscribers
Montana State Library is excited to announce the launch of the Montana State Reference Network (MTSRN) website. This site can be used to learn more about the MTSRN. On April 1, the State Library will begin to collect subscriptions.
What is the Montana State Reference Network?
The Montana State Reference Network is the state-owned real time positioning network that provides centimeter or better accuracy in latitude, longitude, and 2 to 5 centimeter accuracy in ellipsoid height at any given time.
This network is operated with the cooperation of partners that include tribal nations, the Montana Department of Transportation, Montana State Library, counties, educational institutions, and private entities who maintain, operate, or otherwise contribute to the operation of this statewide array global navigation satellite systems (GNSS) reference stations.
How does it work?
As the name implies, the MTSRN is a network of reference stations that collect GNSS observations and send them in real time to a central processing unit sitting in a cloud server where the processor combines the observations and compute a network (or subset) solution. From this network solution the observations errors and corrections are computed and broadcast to rovers (that are logged in to MTSRN NTRIP Caster via internet) within the bounds of the network by mimicking a virtual reference station (VRS) nearby as if the rover is getting correction with reference to the VRS. The user receives centimeter accuracy positional coordinates (latitude, longitude, and ellipsoid height) in the current horizontal datum, NAD 83 (2011), 2010.0. Users can receive orthometric height in the current vertical datum, NAVD 88 by using a current geoid model such as GEOID18 in the receiver.
How does the MTSRN benefit Montana?
RTNs provide machine guidance for grading or superelevation and benefits construction and transportation for critical engineering infrastructure, land surveying, precision agriculture, energy & utility, mining, drones, robotics, public safety and more.
How can I access this data?
The State Library is excited to start offering subscriptions to access real-time GPS data to people and industries across Montana.
Subscriptions will be available beginning April 1.
