Evaluation of Ionospheric Delay Effects on Multi-GNSS Positioning Performance
Ionospheric delay is a significant error source in multi-GNSS positioning. We present different processing strategies to fully exploit the ionospheric delay effects on multi-frequency and multi-GNSS positioning performance, including standard point ...

Positioning with stationary emitters in a two-dimensional space-time [PDF]
The basic elements of the relativistic positioning systems in a two-dimensional space-time have been introduced in a previous work [Phys. Rev. D {\bf 73}, 084017 (2006)] where geodesic positioning systems, constituted by two geodesic emitters, have been ...

Accuracy of a magnetic resonance imaging‐based 3D printed stereotactic brain biopsy device in dogs [PDF]
Background: Brain biopsy of intracranial lesions is often necessary to determine specific therapy. The cost of the currently used stereotactic rigid frame and optical tracking systems for brain biopsy in dogs is often prohibitive or accuracy is not ...

The positioning performance of low-cost GNSS receivers in the Precise Point Positioning method [PDF]
Satellite-based positioning, which started being developed in the mid-1960s for military purposes, is now used in almost every area. For the studies single and/or double frequency receivers are used.

Multi-Frequency Precise Point Positioning using GPS and Galileo data with smoothed ionospheric corrections [PDF]
The poor signal visibility and continuity associated with urban environments together with the slow convergence/reconvergence time of Precise Point Positioning (PPP), usually makes PPP unsuitable for land navigation in cities.

Research Article. Improved Dual Frequency PPP Model Using GPS and BeiDou Observations
This paper introduces a new dual-frequency precise point positioning (PPP) model, which combines GPS and BeiDou observations. Combining GPS and BeiDou observations in a PPP model offers more visible satellites to the user, which is expected to enhance ...

Analysis of the time series of station coordinates - a comparison of the network and PPP approach [PDF]
Based on the example of fourteen selected permanent GNSS stations of the EPN (EUREF Permanent Network) the differences of time variations of coordinates – velocities – resulting from the network and PPP (Precise Point Positioning) solution are studied.
