Precise Point Positioning with Partial Ambiguity Fixing
Reliable and rapid ambiguity resolution (AR) is the key to fast precise point positioning (PPP). We propose a modified partial ambiguity resolution (PAR) method, in which an elevation and standard deviation criterion are first used to remove the low ...

Reliable GPS Integer Ambiguity Resolution [PDF]
To operate, guide and control vehicles in low visibility conditions, it is critical that the states of the vehicle are accurately estimated, which includes the three dimensional position, velocity, and attitude.

Precise Point Positioning Integer Ambiguity Resolution with Decoupled Clocks
Precise Point Positioning (PPP) integer ambiguity resolution has been a challenging topic during the past five years. So far, three PPP integer ambiguity resolution methods – the singledifference between satellites method, the decoupled clock model and

Why Uncertainty Matters - Discounting under Intertemporal Risk Aversion and Ambiguity [PDF]
Uncertainty has an almost negligible impact on project value in the economic standard model. I show that a comprehensive evaluation of uncertainty and uncertainty attitude changes this picture fundamentally.

GLONASS CDMA L3 ambiguity resolution and positioning [PDF]
A first assessment of GLONASS CDMA L3 ambiguity resolution and positioning performance is provided. Our analyses are based on GLONASS L3 data from the satellite pair SVNs 755-801, received by two JAVAD receivers at Curtin University, Perth, Australia. In

A Comparison Between Hard- and Soft-Constrained RTK Positioning With Multiple Reference Antennas
Real-time kinematic (RTK) ambiguity resolution can be improved by engaging multiple reference antennas. The baseline information between the antennas can be taken as true values and used as a hard-constraint; or it can be regarded as weighted, a priori ...

Extended GNSS ambiguity resolution models with regularization criterion and constraints
This paper firstly presents an extended ambiguity resolution model that deals with an ill-posed problem and constraints among the estimated parameters. In the extended model, the regularization criterion is used instead of the traditional least squares ...

Projective resolutions of associative algebras and ambiguities
The aim of this article is to give a method to construct bimodule resolutions of associative algebras, generalizing Bardzell's well-known resolution of monomial algebras. We stress that this method leads to concrete computations, providing thus a useful tool for computing invariants associated to the algebras. We illustrate how to use it giving several

Variable duration fixed failure rate ambiguity resolution
In global navigation satellite system ambiguity resolution, it is common to use a configurable acceptance test, like the popular ratio test, to control the failure rate.

Comparison of Ambiguity Resolution Approaches for Reconstructing Charged Particle Tracks
The key task of most high-energy physics experiments is to reconstruct the trajectories of charged particles, the so-called tracks. The first stage of event reconstruction is the search for candidate tracks, often performed by applying the Kalman filter.
