Kalman-filter-based Gps Ambiguity Resolution for Real-time Long-baseline Kinematic Applications
Resolving the GPS carrier-phase ambiguities has been a continuing challenge for sub-centimeter-level high-precision GPS positioning. In kinematic and long-baseline applications, the challenge turns out to be even greater due to the substantial problems in the observation time series – the decorrelation of biases, the quasi-random behavior of multipath and the correct interpretation of receiver ...
متن کاملEstimation of the Stochastic Model for Long-Baseline Kinematic GPS Applications
We propose a new approach for the stochastic model for long-baseline kinematic GPS positioning which can be derived directly from the observation time series under a simple assumption. The performance of our approach was compared with those of existing approaches for the stochastic model – the elevation-angle dependent function approach, the signal-to-noise ratio or alternatively the carrier-to...
متن کاملGPS/Pseudolite/SDINS Integration Approach for Kinematic Applications
This paper discusses the introduction of pseudolites (ground-based GPS-like signal transmitters) in existing integrated GPS/INS systems in order to provide higher availability, integrity and accuracy in a local area. Even though integrated GPS/INS systems can overcome inherent drawbacks of each component system (line-ofsight requirement for GPS, and INS errors that grow with time), performance ...
متن کاملGPS in Pioneering Dynamic Monitoring of Long-Period Structures
Global Positioning System (GPS) technology with 10–20-Hz sampling rates allows scientifically justified dynamic measurements of relative displacements of long-period structures. The displacement response of a simulated tall building in real time and permanent deployment of GPS units at the roof of a building are described. To the authors’ best knowledge, this is the first permanent deployment o...
متن کاملInvestigation of Long Period Noise at Lasa
The long-period noise in the 20 to 40 second period range limits the identification level at which the surface-wave, body-wave discriminant can be anplied at the Large Aperture Seismic Array (LASA). Therefore, an investigation was made to determine die sources and properties of this noise. Only the long-period vertical array ^.t LASA was considered. Both conventional and high-resolution frequen...
