High-Precision Single-Frequency GPS Point Positioning
The objective of the research described in this paper is to develop a Kalman filter-based functional model for single-frequency positioning which is suitable for low dynamic platforms such as cars or boats. No external sensors are used and the precise velocity information comes from the time-differenced carrier-phase measurements. The Kalman filter combines these measurements with undifferenced...
متن کاملEvaluation of High-Precision, Single-Frequency GPS Point Positioning Models
In this paper we evaluate the performance of singlefrequency, single-point positioning processors with an emphasis on ionospheric delay handling. A number of least-squares processors with singlefrequency code-only and code-and-carrier-phase observables were developed. Processing model hierarchy is based on measurement error handling, starting with a basic code-based navigation solution and prog...
متن کاملA High-Precision, Magnetically Levitated Positioning Stage
High accuracy positioning stages with multiple degrees-of-freedom, or microsteppers, are ubiquitous in industrial manufacturing. These devices are used in probing and inspection systems, in the assembly of disk drive heads, and in semiconductor manufacturing. In semiconductor manufacturing, microsteppers are employed to accurately move silicon wafers in the photolithography process. To guarante...
متن کاملWUB-IP: A High-Precision UWB Positioning Scheme for Indoor Multi-user Applications
High-precision positioning scheme, an important part of the indoor navigation system, can be implemented using an ultra-wide band (UWB) based ranging system. Recently, solutions for precise positioning in dense multi-path and nonline-of-sight (NLOS) conditions have attracted a lot of attention in literature. On the other hand, it is expected that Waveform Division Multiple Access (WDMA) technol...
متن کاملNoise Characteristics in High Precision GPS Positioning
In this contribution we present the results of three different studies in which the method of least-squares variance component estimation (LS-VCE) was used to infer the stochastic properties of GPS data. The three studies cover the GPS geometry-free model, the GPS coordinate time series model, and the GPS zero-baseline model. In the GPS geometry-free model, LS-VCE is applied to assess the preci...
