The Future of GNSS RTK Services & Implications for CORS Infrastructure
A crucial question by GPS receiver network operators relate to ways to recoup network infrastructure investment by establishing profitable service businesses for the data generated by the receivers. One approach is to try to find a core of users who are prepared to pay for the “real-time kinematic” (RTK) services. But this is only feasible if the number of users, and the fees charged, are suffi...
متن کاملImplementing network - RTK : the SydNET CORS infrastructure
As is well known, the limitation of single-base real-time kinematic (RTK) GPS carrier phase-based techniques is the constrained distance between base receiver and the rover receiver due to distance-dependent measurement biases. For high productivity GPS surveying techniques, requiring very fast on-the-fly ambiguity resolution, the baseline length is generally restricted to less than 10km. Howev...
متن کاملSystem Architecture for Server-Based Network-RTK using Multiple GNSS
Improved accuracy and reliability of the real-time user coordinates is expected if GNSS data is processed using the network-RTK technique. Some implementations of conventional network-RTK, e.g. Virtual Reference Station (VRS) techniques, require bi-directional communications via GSM/GPRS since the network server transmits network-corrections to a user, while the user receiver is required to tra...
متن کاملThe Latest Development of a State-wide GNSS Network-based RTK System in Australia
This paper describes the latest developments of an Australian Research Council (ARC) project involving researchers from RMIT University, UNSW, University of Melbourne, Victorian Department of Sustainability and Environment (DSE) and the New South Wales (NSW) Department of Lands (DoL). The aim of the project is to enhance the utility of continuously operating reference station (CORS) networks in...
متن کاملHow will all the new GNSS signals help RTK surveyors?
In the next few years, surveyors using high productivity, real-time kinematic (RTK) positioning and indeed all other precision positioning users will be faced with a barrage of new global navigation satellite system (GNSS) signals from GPS, GLONASS, GALILEO and possibly COMPASS/Beidou2 as well as Satellite Based Augmentation Systems (SBAS) signals and Regional Navigation Satellite Systems (RNSS...
