This article addresses the issue of raising the level of identification of observations with
either single or more split functional models in the squared M split (q) estimation process …

The paper undertakes the subject of spatial data pre-processing for marine mobile
information systems. Short review of maritime information systems is given and the focus is …

Vessel traffic service (VTS) is important to protect the safety of maritime traffic. Along with the
expansion of monitoring area per VTS operator in Tokyo Bay, Japan, inexperienced …

Abstract The Vessel Traffic Service (VTS) systems belong to the fundamental tools used in
ensuring a high level of safety across sea basins with heavy traffic, where the presence of …

The article presents the issue of determining a proper number of competitive functional
models in the square M split (q) estimation. It is assumed in the theoretical fundamentals of …

Outlying observations are undesirable but possible elements of geodetic measurements. In
such a context, the primary and trivial solution is to repeat “suspected” observations. The …

The main aim of this paper is to assess the possibility of using non-conventional geodetic
estimation methods in maritime navigation. The research subject of this paper concerns …

The second half of the 20 th century has made its mark on world history as the era of
information technology and conquest of space. Since 1974, when the first test NAVSTAR …

Satellite measurement techniques have been used for many years in different types of
human activity, including work related to staking out and making use of rail infrastructure …

Abstract Maritime Differential GPS systems (283.5-325 kHz) are today the basic method for
determining the position of vessels in coastal navigation, entering into seaports as well as …
