Analyze Business Models for Implementation and Operation of a Statewide GNSSRTN
(Montana Department of Transportation (SPR), 2022-10) Al-Kaisy, Ahmed; Teixeira, Rafael; Raza, Sajid; Meyer, Benjamin
The Global Navigation Satellite System (GNSS), commonly known as the global positioning system, has become one of the fastest growing emerging technologies delivering location services to various sectors. The applications of geospatial data span every sphere of modern-day science and industry where geographical positioning matters. The list includes navigation, agriculture, surveying, construction, transportation, forestry, mining, and many others. The accuracy and precision of geospatial data using the GNSS Real-Time Network (RTN) technology enable advanced applications in many fields where geospatial data is used; and open the doors for new applications such as the emerging autonomous systems in transportation, mining, and agriculture. This research project is intended to provide information that would help the state’s efforts in the planning and implementation of the Montana GNSS-RTN system. Four major tasks were completed for this project, namely; state-of-the-art review, state-of-the-practice assessment, characterizing Montana existing GNSS-RTN infrastructure, and identifying and cataloging viable business models for statewide GNSS-RTN systems.
GNSS-RTN Role in Transportation Applications: An Outlook
(American Society of Civil Engineers, 2022-08) Raza, Sajid; Al-Kaisy, Ahmed; Teixeira, Rafael; Meyer, Benjamin
Geospatial location service is not only used in measuring ground distances and mapping topography, but has also become vital in many other fields such as aerospace, aviation, natural disaster management, and agriculture, to name but a few. The innovative and multi-disciplinary applications of geospatial data drive technological advancement toward precise and accurate location services available in real-time. Although the RTN technology is currently utilized in a few industries such as precision farming, construction industry, and land survey, the implications of precise real-time location services would be far-reaching and critical to many advanced transportation applications. The GNSS real-time network (RTN) technology, introduced in the mid-1990s, is promising in meeting the needs of automation in most of the advanced transportation applications. This article presents an overview of the GNSS-RTN technology, its current applications in transportation-related fields, and a perspective on the future use of this technology in advanced transportation applications.
The Role of GNSS-RTN in Transportation Applications
(MDPI AG, 2022-07) Raza, Sajid; Al-Kaisy, Ahmed; Teixeira, Rafael; Meyer, Benjamin
The Global Navigation Satellite System—Real-Time Network (GNSS-RTN) is a satellite-based positioning system using a network of ground receivers (also called continuously operating reference stations (CORSs)) and a central processing center that provides highly accurate location services to the users in real-time over a broader geographic region. Such systems can provide geospatial location data with centimeter-level accuracy anywhere within the network. Geospatial location services are not only used in measuring ground distances and mapping topography; they have also become vital in many other fields such as aerospace, aviation, natural disaster management, and agriculture, to name but a few. The innovative and multi-disciplinary applications of geospatial data drive technological advancement towards precise and accurate location services available in real-time. Although GNSS-RTN technology is currently utilized in a few industries such as precision farming, construction industry, and land surveying, the implications of precise real-time location services would be far-reaching and more critical to many advanced transportation applications. The GNSS-RTN technology is promising in meeting the needs of automation in most advanced transportation applications. This article presents an overview of the GNSS-RTN technology, its current applications in transportation-related fields, and a perspective on the future use of this technology in advanced transportation applications.
