[EN]
Robust estimation has proved to be a valuable alternative to the least squares estimator for the cases where the dataset is contaminated with outliers. Many robust estimators have been designed to be minimally affected ...
[EN] Least-squares adjustment yields the most likely solution for a set of redundant data provided the mathematical model is correct and there are only random errors in the observations. When systematic or gross errors ...

[EN] The paper presents two algorithms for the computation of intersection of geodesics and minimum distance from a point to a geodesic on the ellipsoid, respectively. They are based on the iterative use of direct and ...
[EN] Robust estimators are often lacking a closed-form expression for the computation of their residual covariance matrix. In fact, it is also a prerequisite to obtain critical values for normalized residuals. We present ...
Baselga Moreno, Sergio; García-Asenjo Villamayor, Luis(Cambridge University Press, 2008-07)
[EN] In the last decades, robust estimation has been widely applied to overcome the presence of gross errors in observations. Recently it has been shown that robust estimation, if computed appropriately, is able to cope ...

The present paper focuses on the theory of outlier detection in least-squares adjustment. Although the case of a single outlier can be efficiently handled, extensions of the testing theory to the multiple outlier case seem ...
[EN] Multipath is the most limiting factor in many GNSS positioning applications, where it inevitably degrades the attainable precision. Among the different proposals to identify observations affected by multipath, Strode ...
[EN] A Lambert Conformal Conic (LCC) projection with two true-scale parallels of latitudes phi(l)and phi(u)can be recast in a LCC projection with one standard parallel of latitude phi(0)and scalek(0), having the practical ...

[EN] Different approaches have been proposed to determine the possible outliers existing in a dataset. The most widely used consists in the application of the data snooping test over the least squares adjustment results. ...

Knowledge of the actual refraction coefficient is essential in leveling surveys and precise electromagnetic distance measurement
reduction. The most common method followed by the surveyor for its determination is based ...

Baselga Moreno, Sergio(American Society of Civil Engineers, 2011)
The problem of determining the required precision in observations in order to obtain a desired precision in final parameters, classically known as the second order design problem, is revisited in this paper and proposed ...
Distance determination in the open air with submillimetric accuracy is a challenging task
usually carried out with the use of submillimetric distancemeters and costly observation
campaigns. The present paper represents ...
The potential use of GPS technology for precise length determination is currently a topic of
extensive research. A prior work was dedicated to submillimetric length determination over
short baselines and under ideal ...
