Ionospheric Effects on Network-RTK
Ionospheric Effects on Network-RTK A part of the atmosphere is ionized by the UV radiation from the Sun. This part is often referred to as the ionosphere. The resulting free electrons influence the GNSS signals as they propagate through the ionosphere. We have studied how the spatial variations of electron density in the ionosphere affect measurements with network-RTK. The aim is to predict wha...
متن کاملPrecise Real-Time Positioning Using Network RTK
In the classic RTK method using a single reference station the rover needs to work within a short range from the reference station due to the spatial decorrelation of distance-dependent errors induced by the ionosphere, troposphere and orbital errors. The operating range of RTK positioning is thus dependent on the existing atmospheric conditions and is usually limited to a distance of up to 10-...
متن کاملSpeeding Up CORS Network RTK Ambiguity Resolution
An efficient way for the real-time GNSS data processing of CORS stations is to make use of a Kalman filter implementation. Using dual-frequency un-differenced carrier phase and code data as observations, the state vector consists of troposphere zenith delays, differential ionosphere delays, receiver and satellite clock errors and phase ambiguities. Satellite positions are computed in real time ...
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 کاملNetwork-based RTK Positioning Using Integrated GPS and GLONASS Observations
With the recent rapid revival of the GLONASS constellation, it is possible for the GLONASS system to provide Full Operational Capability (FOC) service before the end of 2011. CDMA signals are now additionally modulated onto the first GLONASS-K satellite which was launched on February 26, 2011. It is envisaged that GNSS users will benefit from more visible satellites, better precision and higher...
